Re: HCFC Ban in the EU Effective 1/1/01?

2000-12-22 Thread TinBear

William,

This is a truly valuable forum!!!

Thanks for your prompt email response. Perhaps the updated version is EC No. 
2037/2000.

I was sent a copy of Regulation (EC) No 2037/2000 of the European Parliament 
and the Council of 29 June 2000 on substances that deplete the ozone layer 
and Article 5 of that document does seem to state that HCFCs in refrigeration 
and air-conditioning equipment produced after 31 December 2000 is prohibited 
effective 1 January 2001.

Regards.

Dear Tin

There is indeed a ban on new equipment entering the EU from 01.01.2001.  The
original EU Regulation, which implements the requirements of the Montreal
Protocol, was called EC 3093/94.  this has since been replaced with an updated
version but I do not have the reference to hand.

Although the ban comes into force in 2001 it has already been implemented in
Sweden and Denmark in 1998 and Germany in 2000.  The ban only applies to new
equipment.  It does not apply to second hand or used equipment as long as the
date of manufacture is before the cut off date.

If you need any more detailed information give me a call or send an email.

Environmental Professionals,

Is anyone familiar with a Common Position EC #19/1999, Official Journal of
European Commision, 4/5/99.

I was told that the EC#19/1999 is a European regulation that prohibits the
shipment of equipment containing HCFC into the EU after January 1, 2001.

I am curious whether this EC #19/1999 is truly a European Regulation or
Directive and if so, does it really prohibit HCFC to be shipped into the EU
after January 1, 20001.

Re: Getting Started

2000-10-02 Thread TinBear

Chris,

I am interested in knowing the basis of your response to items 1 and 2, as it 
is contrary to my understanding of the EMC Directive.

Specifically, it was my understanding that unless the manufacturer is following 
ALL of the requirements specified in Standard(s), that they must follow the TCF 
route and obtain a report or certificate from a Competent Body, as outlined per 
Article 10(2) of the EMC Directive states that In the case of apparatus for 
which the manufacturer has not applied, or has applied only in part, the 
standards referred to in Article 7(1) or failing such standards, the 
manufacturer or his authorized respresentative established within the Community 
shall hold at the disposal of the relevant competent authorities, as soon as 
the apparatus is placed on the market, a technical construction file. This file 
shall describe the apparatus. and include a technical report or 
certificate, one or other obtained from a competent body.

If a manufacturer uses their engineering rationale to waive all of the EMC 
testing specified in standards, they have only applied part of the standard and 
as such, the EMC Directive would require that the rationale and the TCF be 
reviewed by a European EMC Competent Body.

Furthermore, I believe that UK's DTI is consistent with EMC Directive's 
philosophy outlined in Article 10(2).  In the October 1992 DTI's Guidance 
Document on the Preparation of a Technical Construction File as required by EC 
Directive 89/336, Section 1.3 outlines the Circumstances where the TCF might 
be used, ii) For apparatus where harmonized standards exist but the 
manufacturer applied that standard in part only, eg where a manufacturer can 
justify that a particular type of apparatus complies with the protection 
requirements of the Directive without performing tests to any or all of the 
phenomena described in the relevant harmonized specifications.

I am interested in learning whether UK has established an updated position 
which allows manufacturer to waive testing (altogether) and still self-declare 
conformity to the EMC Directive through the standards route?

Regards

Tin

 I'm just getting started in the world of EMI and would like to ask a few
 questions.  I'm not sure if I should be going the TCF route or the Standards
 Route.  The company that I work for manufactures products which have many
 variants.
 
 
 1)  Is it EC law that a manufacturer must perform EMI testing before
 applying the CE mark?

No.  In the UK, the Electromagnetic Compatibility Regulations don't require 
testing if you follow the Standards Route.  But you must make the Declaration 
of Compliance before you use the CE mark and be able to provide evidence of 
compliance to the regulatory authorities when challenged.  This can be test 
results, or detailed analysis, or statements etc.  Again, 'testing' per se is 
not a particular requirement.  For instance,  a simple resistive convection 
heater could be stated to Comply because there are no non-linear elements to 
produce or be affected by EMI.  No need to test.  Having said that, testing 
is the only absolutely certain way of proving compliance.  And don't forget 
that the Regulations are Criminal Law!
 
 2)  If a manufacturer follows the Standards Route, does EC law require each
 variant to be tested? 

No.  There is nio statutory need to test.  But you need to provide firm 
evidence, when asked, that the variant is not significantly different in EMC 
terms to the original subject of the Compliance Declaration.  A detailed 
technical statement would suffice, but must be accurate and traceable.  
Again, we are taking Criminal Law here!
 
 3)  If, when testing, the limit is exceeded, can the CE mark still be
 applied?

No.  The CE mark means that ALL relevant Directives have been complied with.  
If EMC limits are exceeded when using the Standards Route then it doesn't 
comply with the EMC Directive.  If the product can't be produced without 
exceeding the limits, then the TCF route to compliance should be used.
 
 4)  Are the services of a Competent Body required in order to put together a
 TCF or can the manufacturer do that on his own?

A TCF is only valid when qualified by a Competent Body.  A manufacturer can 
build his own TCF, or an external Test House/Competent Body can build it, but 
at the end of the day the Competent Body signs/takes responsibility for it.  
Think of a TCF as a new EMC standard which relates ONLY to that particular 
product.  A simple rule is 'if it complies with the Standards then use the 
Standards Route, if it doesn't then use the TCF route.

Hope is useful.

Re:GFCI equivalent in Japan

2000-03-22 Thread TinBear

Tony,

You raised a very good discussion. I have also seen a few Japanese customer 
specifications (and even some European customer specifications)with 30 mA GFCI, 
usually with a 0.1 second trip time.

Based on my research, the 30 mA GFCI, 0.1 second is based on JIS C 8371 
Residual Current Operated Circuit Breaker.   

Now, whether or not 30 mA GFCI would be considered to be suitable for personnel 
protection depends a lot on who you speak with?   

If you ask the compliance safety engineers in the U.S., they'd say Nope, 30 mA 
GFCIs are not for personnel protection, at least not per UL 943, which defines 
shock hazard as A shock hazard is considered to exist at a part of a 
ground-fault circuit-interrupter if: A) There would be current of 6 mA or more 
in a resistance of 500 ohms connected between the part in question and the 
grounded supply conductor, and B) The device would not operate to open the 
circuit to the 500-ohm resistor within the time allowed in paragraph 23.1..   

For the Japanese (and even some Europeans), 30 mA, 0.1 sec. Residual Current 
Devices may very well be considered suitable for personnel protection because 
the trip current and trip time fall within Zone 2 of IEC 479-1, Usually no 
harmful physiological effects.

Being trained under the U.S. philosophy, I probably will not admit publicly 
that 30 mA GFCIs is adequate for personnel protection; although it is 
comforting to know that if someone should expose themselves to a line to ground 
condition, that the 30 mA, 0.1 sec. GFCI should technically trip before any 
harmful physiological effect results, at least per IEC 479-1.

Disclaimer: Electric shock is a very tricky science, it is not only dependent 
upon current and exposure time, but body impedance, frequency, location of body 
exposure, etc.

Re: Warning label sizing.

1999-10-01 Thread TinBear

Kyle,

My response would be .08 inch minimum type size for the letter height in 
the laser label. per the Informative Annex B of ANSI Z535.4.


RATIONALE/BASIS:
Section 4.7.1 of the American National Standard Z136.1-1993, Safe Use of 
Lasers states Design of Signs.  Sign dimensions, letter size and color, 
etc., shall be in accordance with American National Standard Specification 
for Accident Prevention Signs, ANSI Z535 Series (latest revision thereof).  
Figures 1a and 1b show sample signs for Class 2, Class 3a, Class 3b and Class 
4 laser or laser systems.

ANSI Z535.4-1998 Product Safety Signs and Labels has a section in 
Informative Annex B.3.2.13 addressing 'minimum letter height calculations'.  
B3.2.13 Minimum letter height calculations.  Type size is defined in 
points, a term that was used to describe the space required for lead type 
characters.  Point sizes measure from the top of the capital letters to the 
bottom of the lower case letters with descenders (e.g., the bottom of the 
letter g or j etc.).  One point equals 0.01384 inches, or approximately 
1/72 of an inch.  Although type faces vary slightly, a practical guide for 
defining type size is based on using the capital letter H for measurement 
purposes.  Since the character H has no descender, it is possible to use a 
conversion factor of 0.01 inches - 1 point of type size.  Thus, 12 point type 
yields a capital H approximately 0.12 inches high.  For metric purposes, 
use a conversion factor of 3.9 points = 1 mm of height for a capital H.

Recommended Letter Heights For Favorable Reading Conditions:
2 Feet or Less: Viewing Distance (in.)/150
2 To 20 Feet: Viewing Distance ((ft.-2) X (.03)) +.16
Over 20 Feet: Viewing Distance (ft.)/28.6

Recommended Letter Heights For Unfavorable Reading Conditions (All Distances):
Viewing Distance (ft.)X 0.84

Table - Examples of word message letter heights and minimum safe viewing 
distances.  

(Note:  Only the first row is reflected below).
Minimum Safe Viewing Distance - 1 Foot or less
Minimum Letter Height for Favorable Reading Conditions - .08 inches
Recommended Letter Height for Favorable Reading Conditions - .08 inches
Recommended Letter Height for Unfavorable Reading Conditions - .084 inches
(Note:  Only the first row is reflected above).

*.08 inch type is the suggested minimum type size for use on product safety 
signs.

Re: LVD and notified bodies

1999-09-02 Thread TinBear

Kevin,

I had that same issue with I was working with the EMC Directive.   In fact, I 
had five very different EMC test plan signed-off by different EMC Competent 
Bodies.  The bottom line is that interpretations do vary between Notified 
Bodies.   The way they get around this issue, at least with EMC Directive, is 
that once a project has been started by one Competent Body, another one would 
generally not agree to take over the project.  In fact, we were required to 
submit a Declaration of Submittal to two of our Competent Bodies stating that 
the product submitted were not being submitted to any other Competent Body.

So my response to your question of Who rules?... It's whichever Notified 
Body you contracted to do the work.   Once a certificate is issued by one 
Notified Body, another Notified Body technically cannot challenge that 
certification.

In retrospect, I am quite in favor of this because it prevents a manufacturer 
from 'shopping around for the answers they want to hear'.Once the 
manufacturer selects the Competent or Notified Body, they should live by that 
decision or start with another, from scratch.  The Competent Body or Notified 
Body should not be expected to 'adopt' the philosophy of another Competent or 
Notified Body.

  Hi Jeff:
 
 
If a component abnormal test generates excessive and sustained smoke
(several minutes), but does'nt breach reinforced or double insulation, 
nor
emit flame from the enclosure, is it considered a failure?  Intuitively, 
it
seems like it would be, because of toxicity, but I have been unable to 
find
anything in the safety standards to support this.  I have checked EN 
60950,
EN 50178, UL 1012, and CSA C22.2 No. 107.1.
 
 For the purposes of product safety and compliance with safety
 standards, smoke is a permitted emission during fault testing.
 
 The safety issue is whether a safeguard is damaged or breached
 due to the heat which produced the smoke.  If insulation is not
 damaged (as per the hi-pot test), and excessive heat or flame 
 does not breach the enclosure (as per the cheesecloth test), 
 then the product is considered acceptable for the purposes of 
 product safety.
 
 Typically, product safety standards do not address the toxicity
 of smoke.  This is because all smoke contains toxic materials.  
 The only solution to smoke toxicity is to eliminate smoke, which
 means eliminating all overheating situations.  Which is nearly
 impossible.
 
 However, any smoke from a product is likely create fear and
 anxiety in the mind of the user and nearby persons.  Any smoke
 in a clean room will likely be cause for scrapping all stock in
 the clean room.
 
 While smoke always contains toxic materials (e.g., carbon monoxide),
 the concentration of the smoke (toxic material) in the volume of 
 the room together with the room ventilation determines whether or 
 not inhalation of the smoke is likely to cause an injury.  If the
 volume of smoke is small compared to the volume of the room, then
 it is likely the concentration of toxic material will be below the 
 TLV (threshold limit value) for that material.  
 
 So, it is a good idea (for the satisfaction of your customers) to
 eliminate or reduce any significant smoke emissions that might 
 occur during fault testing.

 Rich

Re: Laser pointers

1998-11-11 Thread TinBear
Since we are speaking of illegalities, there are in fact at least two
California Penal Code sections dealing with the use of the unlawful use of
laser devices:

California Penal Code 247.5.  Any person who willfully and maliciously
discharges a laser at an aircraft, whether in  motion or in flight, while
occupied, is guilty of a violation of this section, which shall be punishable
as either a misdemeanor by imprisonment in the county jail for not more than
one year or by a fine of one thousand dollars ($1,000), or a felony by
imprisonment in the state prison for 16 months, two years, or three years, or
by a fine of two thousand dollars ($2,000).  This section does not apply to
the conduct of laser development activity by or on behalf of the United States
Armed Forces.
   As used in this section, aircraft means any contrivance intended for and
capable of transporting persons through the airspace.
   As used in this section, laser means a device that utilizes the natural
oscillations of atoms or molecules between energy levels for generating
coherent electromagnetic radiation in the ultraviolet, visible, or infrared
region of the spectrum, and when discharged exceeds one milliwatt continuous
wave.

California Penal Code 417.25. (a) Every person who, except in self-defense,
knowingly draws or exhibits a laser scope, as defined in subdivision (b), that
projects a colored target on a person in a threatening manner against that
person with the specific intent to cause a reasonable person apprehension or
fear of bodily harm is guilty of a misdemeanor, punishable by imprisonment in
a county jail for up to 30 days.  For purposes of this section, the laser
scope need not be attached to afirearm.
   (b) As used in this section, laser scope means a portable battery-powered
device capable of being attached to a firearm and capable of projecting a
laser light on objects at a distance.

Re: Agency approvals on components in CE mar

1998-10-07 Thread TinBear
Jeff,

Mr. Eszlari asked, Is it true that European safety agency approval for
critical components may not be required for CE?  
Answer, No, it is NOT required (compulsory) for a manufacturer to use
European safety agency approval for critical components.   Having a
certificate from an accredited testing laboratory is always a good idea for
all of the reasons provided by Mr. Eszlari.   The bottom line is that the
manufacturer must be able to demonstrate that the product complies with the
essential requirements of the applicable Directives.   Standards provide a
'presumption of conformity', but it is not compulsory!   

Example: Annex V, 3(b) ... The manufacturer must carry out necessary research
or tests on components, fittings or the complete machine to determine whether
by its design or construction, the machine is capable of being erected and put
into service safely.Remember that the CE marking signifies that the
product meets the provisions of the applicable Directives.   Unless it
specifically states that components require European safety agency, it is NOT
a requirement.

 It is true that a European safety agency approval for critical components
 may not be required for CE, but please be aware that if you purchase such
 a component you should check the declaration and be sure the component was
 tested according to the correct standard with all amendments. You may also
 want to request a copy of the test report for your file.
 
 By purchasing European safety  agency approved components you can be sure
 the component was tested according to the correct standard, and can back it
 up with the component license. Also, if a customer happens to require a
 European safety mark on your product, they will either ask for the
 component licenses or have to spend quite a bit of time reviewing the
 declarations and reports.
 
 Hope this helps in your decision.

Re: CE technical file format

1998-06-10 Thread TinBear
Gary,

UK's DTI published a Guidance Document on the Preparation of a Technical
Construction File as Required by EC Directive 89/336 dated October 1992,
which contains some helpful information on what a manufacturer should include
within a Technical Construction File. 

The key parts of that Guidance Document were also captured within Annex B
(Technical Construction File Route to Compliance of the DTI's UK Regulations
April 1993 Product Standards, Electromagnetic compatibility.

You should be able to obtain the above documents from DTI directly.  For your
convenience, I have included the relevant excerpts below:

Annex B - Technical Construction File Route to Compliance

BASIC REQUIREMENTS FOR A TCF 

Part I: Description of the apparatus: 
i) identification of apparatus; 
ii) a technical description.

Part II: Procedures used to ensure conformity of the apparatus to the
protection requirements:
i) a technical rationale;  
ii) details of significant design elements;  
iii) test evidence where appropriate.

Part Ill: A report or certificate from a 'Competent Body'.

SPECIFIC REQUIREMENTS FOR A TCF

The level of detail required in each of the above sections of the TCF will
depend on individual circumstances, but might include the following:  

Identification of the apparatus 
(a) brand name; 
(b) model number; 
(c) name and address of manufacturer or agent; 
(d) a description of the intended function of the apparatus;
 
(e) for installations - physical location; 
(f) external photographs;  
(g) any limitation on the intended operating environment.   
  

Technical description of the apparatus  
(a) a block diagram showing the interrelationship between the different
functional areas of the apparatus; 
(b) relevant technical drawings, including circuit diagrams, assembly
diagrams, parts list, installation diagrams; 
(c) description of intended interconnections with other products. devices etc.
(d) descriptions of product variants.

Technical rationale 
(a) a brief exposition of the rationale underpinning the inclusion and
balance of the evidence given. 
Detail of significant design aspects 
(a) design features adopted specifically to address EMC problems; 
(b) relevant component specifications (e.g. the use of cabling products known
to minimise EMC problems);   
(c) an exposition of the procedures used to control variants in the design
together with an explanation of the procedures used to assess whether a
particular change in the design will require the apparatus to be retested;
(d) details and results of any theoretical modelling of performance aspects of
the apparatus. 
Test data 
(a) a list of the EMC tests performed on the product. and test reports
relating to them, including details of test methods, etc. 
(b) an overview of the logical processes used to decide whether the tests
performed on the apparatus were adequate to ensure compliance with the
directive; 
(c) a list of tests performed on critical sub-assemblies, and test reports or
certificates relating to them. 

Report or certificate from a competent body 
(a) reference to the exact build state of the apparatus assessed, cross
referencing with Part I of the basic requirements of a TCF; 
(b) comment on the technical rationale; 
(c) statement of work done to verify the contents and authenticity of the
design information in the TCF, cross-referencing with Part II (ii) of the
basic requirements of a TCF;
(d) comment, where appropriate, on the procedures used to control variants,
and on environmental, installation and maintenance factors which may be
relevant;
(e) contain an analysis of the tests performed either by the manufacturer, an
authorised third party, or the competent body itself, and the results
obtained, so as to assess whether those tests indicate that the apparatus
should comply with the essential requirements of the Directive, cross-
referencing with Part II (iii) of the basic requirements of a TCF.

It is envisaged that Parts I and II of the TCF will be written by the
manufacturer in cooperation or consultation with the Competent Body. The
report from the Competent Body should therefore not need to repeat much of the
information contained in Parts I and II.

At the end of the report a detachable certificate will be supplied. This can
be used by the manufacturer as an

MACHINERY DIRECTIVE
I don't know which Directive your new product falls under, but the Machinery
Directive has specific exclusions dealing with demo products, Whereas, for
trade fairs, exhibitions, etc., it must be possible to exhibit machinery
which does not conform to this Directive; whereas, however, interested
parties should be properly informed that the machinery does not conform and
cannot be purchased in that condition;. 

Article 2(3) of the Machinery Directive also states, At trade fairs,
exhibitions, demonstrations, etc., Member States shall not prevent the
showing of machinery or safety components which do not conform to the
provisions of this Directive, provided that a visible sign clearly indicates
that such machinery or safety components does not conform and that they are
not for sale until they have been brought into conformity by the manufacturer
or his authorized representative established in the Community.  During
demonstrations, adequate safety measures shall be taken to ensure the
protection of persons.  (89/392/EEC as ammended by 93/44/EEC).

In addition, the European Commission (DGIII) also published a Machinery
Working Party, 89/392/EEC Committee, Document 93.6 rev. 1 specifically
answering this question:
PQ.53  If a manufacturer installs machinery on the premises of a potential
customer for him to evaluate it but the machinery is not sold and remains the
property of the manufacturer, does it have to bear the CE Marking and meet
the other requirements applicable to it?
PA.53 This is a typical case because as long as the machinery remains the
property of the manufacturer and as long as the operators are the
manufacturer's employeed the machinery has not been placed on the market; as
soon as the satisfied customer takes delivery the machinery has to comply
with the Directive, bear the CE Marking, etc.
The manufacturer has to make sure that a notice is affixed in the vicinity
saying that the machinery is not in conformity with the Directive (Article
2(3)).
The situation is different if the manufacturer has supplied the machinery for
evaluation by the potential customer. In this case, the machinery has to be
considered as placed on the market (handed over provisionally but handed over
all the same) and placed in service in accordance with Article 2(2) and must
be entirely in conformity with the Directive.

EMC DIRECTIVE
Although this issue is not specifically addressed in the text of the EMC
Directive, the general philosophy above is fairly consistently applied for
products falling under the EMC Directive.   Specifically, if a product is
'placed on the market' or 'put into service', it would require to be fully
compliant with the EMC Directive.   The position is backed up by a European
Commission's publication, Guidelines on the application of Council Directive
89/336/EEC of 3 May 1989 on the Approximation of the Laws of the Member
States relating to Electromagnetic Compatibility Brussels, 25  26 October
1993.  (I believe a more recent draft or perhaps even the final updated of
this Guidelines has just been released and is even posted in the RCIC in
electronic format, http://uc.com/bin/dbml.dll?template=rcic/emcguide).  

Article 2.1 of this Guideline hadn't changed too much and it notes
specifically that The placing of a product on the market does not concern:
   - the disposal of the product from the manufacturer to his authorized
representative established within
   - the Community who is responsible for the manufacturer for ensuring
compliance with the Directive; 
   - importation into the Community market for the purpose of re-exportation,
i.e., under the processing traffic system 
   - the manufacture of the product in the Community market for the purpose
of exportation to a third country; 
   - the display of the product at trade fairs and exhibitions. 

SUMMARY (PERSONAL COMMENT/INTERPRETATION):
Based on the above sources, my comment is that as long as the product in
question is not being placed on the market (meaning the system is not sold
and is being demo'd by the manufacturer's personnel only) or put into
service, and a notice stating that product is not in conformity, you may ship
a non-CE Marking product.  There's no maximum time period that I am aware for
a system to be considered as a display at the trade fair and no specific
paperwork other than the notice needed.   Depending on your product, it may
have initial problems entering the EU, so a letter or declaration stating
that the product is only intended to be a demo product and will not be placed
on the market operated or put into service, may be a good idea.   

Hope this helps.

Tin

Re: Names of Voltage Levels

1997-05-01 Thread TinBear
To expand on Eric Henning's comment on voltage definition, EN 60204 (similar
to IEC 204), has yet a different definition for PELV:

6.4  Protection by the use of PELV (Protective Extra Low Voltage)

This measure is intended to protect persons against electric shock from
direct contact and indirect contact (see IEC 364-4-41).

PELV circuits shall satisfy all of the following conditions:

a) limitation of maximum nominal voltage to 25 V a.c. or 60 V d.c.;
b) limitation of maximum current (in case of failure) to 1 A a.c. or 0.2 A
d.c.;
c) limitation to 80 mm2 of any area not protected against direct contact;
d) usage only indoors with dry conditions;
e) the source of supply and live parts of such circuits shall be separated or
isolated from circuits with higher voltages according to 6.3.3 and 15.1.3;
f) one side of the circuit or one point of the source of the supply of that
circuit shall be connected to the protective bonding circuit associated with
the higher voltages;
g) exposed conductive parts associated with such circuits shall be either
separated or isolated from higher voltage circuits in accordance with 6.3.3
or connected to the protective bonding circuit associated with the higher
voltages;
h) plugs and socket-outlets shall comply with the following:
1) plugs shall not be able to enter socket-outlets not in accordance 
with
this subclause; and
2) socket-outlets shall exclude plugs of circuits not in accordance with
this subclause;
i) where such circuits are used as control circuits, they shall also fulfil
the relevant requirements of clause 9.

So, I certainly agree that not all ELVs are equal.


Fwd: input current rating versus input circuit protection

1997-04-28 Thread TinBear
Bob,

There are a few references to the 125% rule (or 80% rule) in the National
Electrical Code (NFPA 70):

1.  NEC Article 384-16(c) for Panelboards- Continuous Load.  The total load
on any overcurrent device located in a panelboard shall not exceed 80 percent
of its rating where, in normal operation, the load will continue for three
hours or more.
   
Exception: An assembly, including the overcurrent device, shall be permitted
to be used for continuous operation at 100 percent of its rating where it is
listed for this purpose.

2.  NEC Article 210-22 for Branch Circuit - Other Loads.  The rating of the
branch-circuit overcurrent device serving continuous loads, such as store
lighting and similar loads, shall be not less than the noncontinuous load
plus 125 percent of the of the continuous load.  The minimum branch-circuit
conductor size, without the application of any adjustment or correction
factors, shall have an allowable ampacity equal to or greater than the
non-continuous load plus 125 percent of the continuous load.
 
Exception: Circuits supplied by an assembly, together with its overcurrent
devices, that is listed for continuous operation at 100 percent of its
rating.

Hope this helps.

Hello,

Are there requirements or guidelines around what a power supply input
breaker should be rated for a given nominal input current assuming the
power cord is rated appropriately? Looking through the harmonized 950
standard I did not come across anything.

I seem to recall seeing a 125% figure once but don't remember where that
was. I would assume that the circuit breaker would be some percent
higher than the nominal input current rating to prevent nuisance trips
and to take into account surge current or perhaps this is addressed by
the trip characteristics of the breaker. 

To give an example, if the unit has an input current rating of 16amps,
is there a rule which states the input circuit breaker must fall within
some rating range.

I am not sure what industry you are in, but for Industrial Machinery, I know
of two standards addressing the use of red colored indicator lights.   Hope
this helps:

EN 60204-1 - Safety of Machinery - Electrical equipment of machines, Part 1,
Table 3: Color for indicator lights and their meanings with respect to
condition of the machine. (Note: I have modified the layout in order to fit
into this email)

Colour:  RED
Meaning:  Emergency
Explanation: Hazardous condition
Action by operator: Immediate action to deal with hazardous condition (e.g.,
by operating emergency stop)
Examples of application:  Pressure/temperature out of safe limits; Voltage
drop; Breakdown; Overtravel of a stop position.

NFPA 79 - Electrical Standard for Industry Machinery, Table 8 - Color coding
for pushbuttons, indicator (pilot) lights, and illuminated pushbuttons:
(Note: I have only included the Red color for indicator (pilot) lights and
again modified the format to fit into this email)

Color:  RED
Device Type: Pilot Light
Typical Function: Danger or alarm, abnormal condition requiring immediate
attention
Examples: Indicatoin that a protective device has stopped the machine, e.g.,
overload

By the way, I don't interpret the above color code to be directly applicable
for visual display terminals, although I wouldn't put it pass third parties
to interpret it so.

Fwd: IEC 1010-1 Safety Switch

1997-01-15 Thread TinBear
Mark,

You may want to check EN 418 'Functional Aspect of Machine Emergency Stop
Equipment.'   In it, it does cover some of the constructional requirements
noted in your email.

Particularly,

4.4.1  The emergency stop actuators shall be designed for easy actuation by
the operator and others who may need to operate them.  Types of actuators
that may be used include:
  - mushroom-type push buttons;
  - wires, ropes, bars;
  - handles;
  - in specific applications, foot-pedals without protective cover...

4.4.2  The emergency stop actuators shall be positioned for easy access and
for non-hazardous operation by the operator and others who may need to
operate them.
NOTE.  Measures against inadvertent operation should not impair
accessibility.
Personal Comment:  You may be interested in knowing that EN418 does not
either require or prohibit the use of a shroud/collar/guard.  While some
standards (e.g. ANSI/RIA 15.06) specifically calls out 'unguarded'.

4.4.3  The emergency stop actuators shall be colored red.  As far as a
background exists behind the actuator and as far as it is practicable, it
shall be colored yellow.

4.1.2  The control device and its actuator shall apply the principle of
positive mechanical action (see 3.5 of EN 292-2).
NOTE.  A control switch with positive opening operation, is an example of a
suitable control device.  According to EN 60947-5-1 (3rd part, subclause
2.2), positive opening operation (of a contact element) is ?the achievement
of contact separation as the direct result of a specified movement of the
switch actuator through non-resilient members (e.g., not dependent upon
springs)?.
Personal Comment: FYI.  Some European testing laboratory interprets this as
requiring a dual contact EMO actuator.

Hope this helps!

Annex I, Section 1.7.3 of the Machinery Directive for Markings states, Where
a machine part must be handled during use with lifting equipment, its mass
must be indicated legibly, indelibly and unambiguously.   (91/68/EEC)

1.   Does 'handled during use' include maintenance and servicing?
2.   Does 'with lifting equipment' mean only those parts which are intended
to be lifted with lift assist device are required to be marked with weight?

3.   Does anyone know of any standard (Occupational, Ergonomics or Product

would really appreciate the standard title and number of the standard,

Standards Route vs. Essential Requirements Route

1996-04-26 Thread TinBear
Product Safety Professionals,

The 'New Approach' adopted by most European Directives is intended to enable
manufacturers to declare conformity via EITHER the 'essential requirements'
OR  the 'harmonized standards' -- With the understanding that conformance to
harmonized standards (as listed in the Official Journal of the European
Communities) provides a 'presumption of conformity' to the Directives.  

For manufacturers who are currently declaring conformity via the harmonized
standards route for Machinery and/or Low Voltage Directive, I would really be
interested in the following:

1.  When a manufacturer declares conformity to a list harmonized standards,
are they also, in effect, declaring conformity to all of the 'Normative
References' called out within the harmonized standards?   

1A.  Follow-up to Question No. 1: If the harmonized standards you declare
against references other PrEN or IEC standards in the 'Normative References'
that are NOT specifically listed in the Official Journal of the European
Communities for the Directive?

2.  If a manufacturer chooses to pursue the harmonized standards route, who
determines whether the manufacturer has actually applied ALL of the
applicable standards.  In the case of a large, multi-module industrial
machinery, a manufacturer can easily be expected to comply with EN 60204, EN
292, EN 349, EN 418, EN 294, EN 457,  EN 1050, etc.   (Keep in mind that even
if you utilize a Competent or Notified Body, the manufacturer is still
self-declaring!)

3.  For manufacturers that declare conformance to the standards route, what
happens when new PrEN standards become harmonized and published in the O.J.?
  Will the manufacturer be expected to stop all shipment or is there an
official body who will allow manufacturers a certain grace period to bring
their products into compliance with the new requirements?I ask this
question because I have never seen any grace period allotted when the
European Commission publishes an update adding more and more harmonized
standards to the Directive.

4.  Rhetorical Question (I think):  Which route opens up more product
liability to manufacturers, standards route or essential requirements route?

I would really appreciate any feedback, ESPECIALLY IF THE RESPONSE IS BACKED
BY A PUBLISHED POSITION FROM AN OFFICIAL EUROPEAN SOURCE (SUCH AS THE
EUROPEAN COMMISSION OR EUROPEAN COMPETENT AUTHORITIES).

Best Regards.

Tin
