George:
I would be interested if you have had any response made directly to
you on this, as I have not seen any responses come across. Anyway,
here are my comments.
I have a chart from TUV Rheinland also and it matches what you have
stated regarding products certified before March 1, 1995 to
EN60950:1988/A2:1991 are valid until 3/1/2000. I think the problem
could be that you now have to re-certify *your* product since it is
now no longer valid, and it is now later than March 1, 1995 so
EN60950:1992/A2:1993 now must be used (at a minimum). I would also
assume then that any component used in your system must also meet this
later version.
If this is correct, then it really doesn't make much sense to me. How
can the power supply manufacturer still sell their product with a
valid approval, but another company cannot use it in their new
product?
The January 1, 1996 date that you mentioned also confuses me a bit.
My chart from TUV states that products complying with EN60950:1988 are
valid until 3/1/1996.
Any further comments?
..Mike

Hello All,
My question involves license upgrades for EN60950. I have an ITE product that
was tested and approved to 60950 1988.
TUV notified me in April, 1996 that, as of Jan 1st 1996, my product license
was no longer valid and that I would have to update to EN60950 A2 1993
(minimum). The gating factor here turns out to be the third party power supply
which meets EN60950 A2, 1991. There would be an additional cost (payable to
TUV of course) involved to upgrade the power supply license not to mention any
redesign. I'd rather not go through this if it's not necessary.
I have a chart which explains the transition periods for EN60950. This chart
comes from TUV. The way I am reading it, it tells me that for products
certified before March 1 1995, EN60950 A2 1991 is good until 3/1/2000.
Is my interpretation correct?? or is EN 60950 A2 1993 the minimum
acceptable version for existing ITE products?
As always, all related view points are appreciated.
Thanks,
