Friends and colleagues:
 
Customer needs to perform EMC testing (EN 60601-1-2:2007) on a large medical
device that is rated to operate 240VAC/60Hz or 220VAC/50Hz.  They intend to
use the reports to support an FDA submittal for sales in the US and CE marking
for sales in the EU.  Is it typical that the testing is performed twice, once
with power input at 240/60 and again at 220/50?

Not quite. Twice, yes, but 230/50, not 220/50.

Hi,
Cenelec Guide 25 answers this in its Clause 4 (k):


When there is an undated reference to a basic standard, then
either the latest edition or (if the date of withdrawal of
conflicting standards associated with the latest edition has not
expired) the superseded edition may be applied. After the date
of withdrawal, the latest edition shall be applied.


So it's the #2 in your question.

To all:

I'm reading EN 60601-1-2:2001, and I'm not clear on a sentence in Annex 
ZA. It says:
"For undated references the latest edition of the publication referred
to 
applies (including amendments)." 

1) Is it the 'latest edition' when EN 60601-1-2:2001 was published?  The

annex lists the valid edition at that time.  For example, EN 
61000-4-4:1995

2) Or is it the 'latest edition' at the time the system is tested?  In 
this case, EN 61000-4-4:2005

Well, the emissions test applies the limits of CISPR-11; A or B depending
on what level of protection must be afforded radio users.  You'll remember
that there has been some controversy over approving use of electrosurgical
equipment in residential environments.  I'd think a good deal of the answer
comes from one's customers.

Would hospitals tolerate interference with RF patient monitoring?  ER
ambulance comms?  How often, and how much? Running an electrocautery device
might be tolerated for a few moments; a constant dead carrier on-channel

asking too much of a standard for devices to prescribe interference levels
for facilities. But it would not surprise me if there were a European EMC
standard for medical facilities.

You haven't overlooked anything Bob.  The standard was written to allow the
intended use environment dictate the emissions class.  In most of Europe, the
hospital is considered a Class A emissions environment (Dutch Natioanl
Committee doesn't like that).  Home use is clearly Class B.  One of the tasks
our committee (SC62A MT-23) is tasked to do is create recommendations for
emissions and immunity levels for other environments such as transport
(ambulance, air, etc).

In the 2002 version of EN 60601-1-2, I cannot find specific emission level
requirements for equipment that is sold for use in a hospital. It seems
common sense to me that you would want your equipment to conform to Class B
especially if you are using it in an operating room or an intensive care

Re: EN 60601-1-2/ EN 55022: 1998

2003-01-05 Thread John Barnes

David,
EN 55022:1998 + Amendment A1:2000 was listed in the Official Journal of
the European Community on 26 JUL 2001, in C208 Volume 44.  So you have
had the *option* of using it since then.  It is still included in the
latest listing of harmonized standards for the EMC directive, which came
out 7 DEC 2002, in C304 Volume 45.  The date of cessation of presumption
on conformity of the superseded standard (DOPOCOSS) is 1 AUG 2003.  

So EN 55022:1994 and its amendments are valid for only another seven
months.  This worries a number of EMC and design engineers that I know,
because EN 55022:1998 has Conducted Common Mode Voltage/Current Limits
for Telecommunication Ports that aren't in EN 55022:1994.  And to date,
local area network (LAN) ports like Ethernet have had a very hard time
meeting these limits.

If you would like a lot more information about EN 55022, please read our
web page about emission standards for ITE at:

Dear All,
I have read in various places that the new edition of IEC/EN 60601-1-2
is in
effect (FDA in the US).
As yet, only EN 60601-1-2: 1993 is listed in the OJ (December 2002).
Does anyone know when the new edition will be listed in the OJ and thus
become official?
Regarding EN 55022: 1998 + Amendment A1: 2000, I have also read  that
the
application of this standard is being delayed. Does anyone have any
information as to when it will become applicable?
Thanks

RE: EN 60601-1-2

2002-09-24 Thread Jim Conrad

It seems a bit strange that they have not listed it in the OJ yet
but I am told it is coming soon.  I think the important thing is
that CENELEC approved it in Sept of 2001 and have now published the
DOR, DOP, DOW on their web site.  Now we just have to wait for the
OJ publication that should happen in November.

Best Regards,

Jim

RE: EN 60601

2002-08-28 Thread Peter Merguerian

Kim,

I checked the IEC website and they have a list of all the TRFs in the
following link. Unfortunately, I was unable to locate the 
EN 60601-1 TRF

https://domino.iec.ch/webstore/home.nsf/webstore_search.htm?OpenPage

Please note that the IEC 601-1 TRF I have (received from the test agencies
we work with), states that the TRF originator is UL. Therefore, for your
copy you should try by calling the UL office in Denmark (Demko) or the UL
office in Frankfurt, Germany.

Hello All-

I've been trying to get some information on EN 60601-1.  The 1995 CENELEC 
catalog lists this standard, but when I called Global Engineering and BSI 
to get costs, they didn't have it on their databases.  They did have EN 
60601-1-1.  Is EN 60601-1-1 the appropriate part 1 standard?  Does EN 
60601-1 exist anymore?

Thanks in advance.
