Dear Mr Balasubramanian, Looks like you need to try and use another National Recognized Test Laboratory (NRTL). Have you tried TUV Rheinland - the North American office is NRTL accredited by OSHA and Standards Council of Canada - Out of 19 countries in Asia, TUV Rheinland has 8 offices in India with test laboratory capabilities for world markets. http://www.tuv.com/in/en/regional_offices.html Best Regards, Peter Merguerian

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? Sincerely SCM Microsystems (India) Pvt. Ltd. K.
