CE (LVD) for Fruit Juicers

2002-06-19 Thread Loop, Robert

Hi Group,

Looking through the OJEC LVD Standards list, I could not find under EN 60335 
and its many parts a particular part that covered a juicer.

Does anyone know which particular part of this standard this product falls 
under?

Also, not having seen this device, if it has blades like a blender, will the 
Machinery Directive also be applicable?

Thanks for sharing your knowledge.

EN60204-1 Question

The definition of controlgear in EN60204-1 is somewhat vague to me.  If I 
have a machine that has an operator display, keyboard and mouse that are an 
integral part of the equipment (which I would define as the operator control 
station), are these devices considered to be controlgear within the meaning of 
the standard?

RE: Mains cords

2002-01-15 Thread Loop, Robert

Hi Rob,

The quick answer to your question is no.  If you do not supply the
cordset, you must supply a description of the cordset that is suitable
for your equipment.  The description can be in the form of a flyer or a
part of your installation guide and in the language of the country in
which it is sold.

The description should include information on the following:

*   The maximum length (4.5 m/15 feet)
*   The nominal size of the conductors expressed in mm squared
*   The cordage should bear the HAR mark of the approval mark of
the country in which it is sold
*   A description of the attachment plug
*   If the cordset is used as the disconnect device, there should be
a statement about plugging it into an unobstructed wall outlet

Grounding Continuity Testers for UL 60950

2001-11-14 Thread Loop, Robert

Good Morning Group,

Does anyone have any information regarding high amperage continuity
testers that might be purchased for testing compliance with Sub-Clause
2.6.3 of UL 60950?

My concern is regarding high amperage equipment and the requirement to
test at two times the circuit current.  

We are looking at a product rated at 100 amps.  Where in the world can
we get a tester that would go up to 200 amps with a 12 V output?

RE: Risk assessment

2000-12-08 Thread Loop, Robert

Hi Stig,

One of my side jobs is in the Army National Guard Field Artillery.  We
perform a risk assessment at each firing point we pull into using an Army
manual, FM 100-14 (Risk Management).  I was surprised to see how closely
their documentation parallels EN 1050 in many aspects.

Here's a quick look at some of the terms and definitions used that relate to
your inquiry:

Hazard Severity:

*   Severity -  The expected consequences of an event in terms of degree
of injury, property damage or mission-impairing factors.
*Catastrophic - Death or permanent total disability, system loss,
major damage, significant property damage or mission failure.
*   Critical - Permanent partial disability, temporary total disability
in excess of three months, major system damage, significant property damage
or significant mission degradation.
*   Marginal  -  Minor injury, lost workday incident, minor system
damage, minor property damage, or some mission degradation.
*   Negligible - First aid or minor medical treatment, minor system
impairment, little or no impact on mission.
Hazard Probability:

*   Probability - The likelihood an event will occur.
*   Frequent -  Occurs often or continuously experienced.
*   Likely -  Occurs several times.
*   Occasional - Occurs sporadically.
*   Seldom - Unlikely, but could occur at some time.
*   Unlikely - Can assume it will not occur

Hope this is helpful.

 Hi Group, Dec 07,2000
 I am in the process of establishing the potential for an injury from a
 hazard.
 I can get a reasonable 'expression' to describe the potential for a hazard
 to turn into an accident (event). I am looking for the  words that
 classifies the degree of an injury. Can some one direct me to some
 standard
 definitions?
 Do we base it on the length of work stoppage? i.e. a minor burn on a
 finger
 tip smarts for an hour or two. A good shock working with vacuum tubes,
 300V,
 slowed you down for the rest of the day and so on.
 
 Has some one worked out a practical scale for the degree of an injury. It
 can be numbers or words as long as they are defined. If it does not exist
 let us generate one that we all agree on.-- or most of us.
 
 When it comes to property damage I think that a monetary replacement cost
 would be expressed in 'small', 'medium', 'large' etc where each is defined
 in 'very' general monetary terms.
 
 Thank you for your assistance.

RE: Got another beef about an NRTL (haven't we all?)

2000-10-25 Thread Loop, Robert

Hi Tania,

At Wyle Laboratories (one of the many NRTL's), we typically will accept test
data from another NRTL.  Our assumption is that other NRTL demonstrated
proficiency to OSHA requirements and probably many others (A2LA, NVLAP, ISO
Guide 25, etc.), hence their test data is assumed to be valid.

It is not practical to retest every approved component or sub-assembly as if
it had never been investigated by another NRTL.  The time and cost to the
customer would put us out of the product safety business.  Each standard
that we investigate a product to is done on a clause-by-clause basis to
ensure nothing is missed.  And the test methodology is adequately described
in the standard to ensure uniformity of testing.

As long as the COA's are reviewed and tested accordingly in the end-product
application, we have done our job in ensuring the safety of the final
assembly.

One of the complaints from industry that has lead to worldwide harmonized
standards was that different countries were using safety marks as a trade
barrier.  My personal opinion is that this holds true with any NRTL that
will not accept test data from another NRTL without a signed MRA in place.
It is not an easy accomplishment to achieve NRTL status, OSHA holds the bar
pretty high up. Refusing to accept test data from another NRTL, is a way of
saying that OSHA doesn't know its business on how to qualify a lab (again,
my opinion).

UL has a stranglehold on component recognition by requiring retesting of any
component approved by another NRTL.  The net effect is that this denies a
large segment of business to its competitors.  Fair? Hardly.  Smart business
strategy? Absolutely!

That is my not-for-profit opinion and not my employers.

 Subject:  RE: Got another beef about an NRTL
 Importance:   High
 
 
 All right, let's get specific here and actually use some names!   UL has a
 Mutual Recognition Agreement with CSA to accept each other's test reports.
 This agreement also specifies details about how they conduct the various
 tests (it used to be that earth leakage current measurements were
 performed
 differently by the two agencies).   The agreement also allows them to
 harmonize standards, and many have been harmonized since the MRA was
 first
 signed.   Where the standards still differ, my understanding is that both
 UL
 and CSA will perform both sets of test to satisfy both agencies'
 requirements.
 
 I am not aware that MRAs exist between the different NRTLs.   And how is
 one
 NRTL going to know whether the test procedures are the same between the
 different NRTLs?   In other words, there is no allegiance between them.
 And yes, they do compete.   But so did UL and CSA, but now they sing the
 same tune.   
 
 Any NRTL mark is good, per OSHA and the U.S. NEC, for end-use product.
 But
 if you are incorporating components and other equipment into your systems,
 you need to specify your expectations when you purchase parts.   We
 specify
 X NRTL and we get that.

 Group,
 
  What about another scenario that I have been in with two NRTL's.
 For the sake of embarrassment,lets call them 'NRTL A' and 'NRTL B'
 
 Firstly any components or equipment recognised or listed by an NRTL are
 deemed
 'acceptable' to OSHA so long as it is used as prescribed in its conditions
 of
 acceptability or use. so can I presume that as OSHA accepts any NRTL mark
 they
 are all of equal standing.
 
 Why is it then that NRTL A will not accept a power supply approved by NRTL
 B.
 The latter is true for NRTL B who will accept NRTL A's mark with no
 problems
 (in
 all cases the conditions of acceptability are followed)
 
 So long as the conditions of acceptability are followed and there are no
 engineering reasons for NRTL A to reject NRTL B's approval then what
 happens
 next. Is there any recourse or would we have to go to one NRTL and get the
 whole
 lot retested. If there is no engineering reason, can an NRTL reject
 anothers
 recognition just because it distlikes it or maybe sees it as competition!
 
 Has anyone else had a similar experience, if so what did you do to resolve
 it
 without paying out for more NRTL approvals on an already recognised
 component.
 
 Any comments would be greatly 

IEC/EN Standard for Independent Lamp Control Gear

2000-10-02 Thread Loop, Robert

Group:

I need information on what standard covers an independent lamp control
device.  This product is used in a commercial environment, has a data
interface to a computer and is used to turn fluorescent light fixtures on
and off (not dim).  It is self-contained in its own enclosure and uses
electro-mechanical relays to provide mains power to a series of lights.

It was suggested by another forum subscriber that we look at EN60598-1
Luminaries. Unfortunately, in order to look at an EN standard, one
generally has to purchase them and they are not inexpensive.

To make a long story short, EN60598 only covers the light fixture itself,
not the device that is used to turn it on and off.  After reviewing all of
the standards covered under the LVD in the OJEC, nothing jumps out and says
here I am.

The only standard I could find that might be applicable:

EN60669-2-2:1997 - Switches for household and similar fixed installations.
Section 2: Electromagnetic remote-control switches.

Can anyone say yes, you're right, or no, you're out in left field?  

Any help is greatly appreciated.

RE: US Approval

2000-09-29 Thread Loop, Robert

Daryl:

The last information that I have (and somebody please advise if this is
outdated), is that not one EU test lab that has applied for NRTL status has
been approved by OSHA.

This seems to be the main sticking point for implementing the US-EU MRA.  In
other words, it exists, but is not yet implemented.

So, to answer your question, if a product being sold in the USA requires
NRTL approval (it doesn't have to be UL, it can be any of the other NRTL's),
then having CE marking is not adequate.

 between the EU and the US?
 If so does this mean that electrical and mechanical products tested to CE
 standards do not need further approval (UL?) to be marketed in the states.

as close as possible to the point of production where the product is boxed
up for shipping and/or storage.

The purpose of this is to try and find a defect in the primary side of the
product wiring that may have been induced as part of the assembly process,
such as a cable being pinched where the insulation is now broken.

Even if the component power supply you are installing in your product is
Listed (most are Recognized), there may be an instance where someone on the
production line had too much weekend and wired something incorrectly (such
as the input to the supply).  In my days of working for a computer
manufacturer, I can recall a specific instance where a listed molded
cordset had ground and line reversed on one end.  What a happy surprise for
the test operator that was.

Bottom line is that the production hi-pot test is the last line of defense
in assuring that the manufacturer is not sending out a liability inducing,
honey, we just lost the farm death trap.

 Subject:  Why routine hipot is required.
 
 
 I've been asked why a routine hipot test is required on an end assembly
 computer when it uses a Listed power supply that has already been hipot
 tested.  So far I don't like the way I've worded my response.  Basically
 what I've said is that a power supply is approved as a component.  The end
 safety of the device depends on the installation.
 
 Can anyone add some more beef to this statement.  Thanks.

EN61010-1 Question

2000-05-09 Thread Loop, Robert

Group:

A question on interpretation of Clause 6.3.1.1 and 6.3.1.2:

If a product has an operator accessible cable that exits the equipment and
operates normally at a level of 250 Vdc /200 uA, is it required to be marked
with the hazardous voltage label?

The cable is a probe where the user (a trained technician) could touch bare
metal on the probe operating at the level noted.

My thanks to those that respond.

CE Informative Report

2000-05-09 Thread Loop, Robert

Dear Group:

Could someone explain to me what a CE Informative Report is?

How does this differ from a normal test report?  Or is testing even
involved?

My thanks in advance to those who reply.
