RE: IEC60950 (1992) 2nd edition

2003-04-01 Thread Peter L. Tarver

Amund -

I forgot to mention: or against the requirements in CSA22.2
No 60950-1-03/UL60950-1 (publication dated 1APR2003).  This
should be your preferred standard for Canada and the US,
going forward.

 Amund -

 Neither CSA nor UL will accept new product
 certifications using CSA 22.2 No 950-95/UL1950,
 3rd ed, as of 1APR2003.  You will need to submit
 against CSA 22.2 No. 60950-00/UL60950, 3rd ed.

 The implication is that any reports you may have
 for the power supply are probably inadequate in
 and of themselves and .  On the bright side,
 there were not very many changes to either
 IEC60950 or the CSA/UL standard that would
 negatively effect a power supply, so chances are
 good that it will comply, provided the individual
 safety critical components meet the mandatory
 requirements in Annex P.1.

  If you have a Power supply unit tested according
  to IEC60950 (1992) 2nd
  edition, will it fulfil UL 1950 3rd ed ?
 
  In other words, is  IEC60950 (1992) 2nd edition
  still valid for UL approval
  ?

I do know that for Telecom Power Distribution Units that Listed Circuit
Breakers will now be required in place of Supplementary Protectors which
were allowed under UL1950.

If you are actually refering to EN 60950:1992 + A2, the date in CC paragraph
is listed as March 2000, so any certification may no longer be valid.

Assuming the standard used for the investigation is still valid, I would still
assume that , due to annex C, withstand test levels, and other national
deviations (UL is more sensitive to flame rating of materials), that you would
still have to do some additional testing before a NRTL would recognize the
unit. Note that any test data that does not clearly indicate that there is no
fire hazard with all materials and construction would be suspect.

If you have a CB report for the unit, submit it to UL and see what they
say 

I speak only for myself. 

Good luck, 
Brian
