Dear Experts,
We submit most of products to UL for 60950 listing. Almost 95 % of
our products are UL listed. We find it very difficult to complete the
cycle. Many times we come across situations that the parts used are not
meeting UL spec. and a redesign is inevitable. This further complicates the
things and delay the cycle. We look for some consultants who can help us by
participating from the design review stage itself.
The most sad part is many times we submit the product to UL for
preliminary inspection during the proto stage and UL (India office located
at Bangalore) gives pass report. Then we go for pilot production
(simultaneously we initiate procurement for mass production also) and
submit the pilot samples to the same UL office for final certification. At
this time UL is coming with new findings and ultimately product fails to
get UL listing. All the times I am sure that there is no difference between
the proto samples and pilot samples. Mostly some resistor values get
changed between proto and pilot.
It is not clear to me whether it is the competence issue at UL India
or UL is greedy in money making. I look for advise from the experts of this
forum. I have been told that UL Taiwan is more proficient in 60950
standard. Is this true?
