I have a complaint about a certification process where agencies are providing approvals of little value. There are products for sale which have been reviewed (for example) to UL 1950, and are currently being manufactured and UL recognized. UL 1950 is a withdrawn standard, replaced by UL 60950. I have no problem with that since UL has conducted an IEC Sector Review Process which assures the product has no safety shortcomings with regard to the current standards. For standard changes affecting safety, a requirement effective date – RED is established and applied to the product.
However a company wishing to use this product has a problem with the component recognition since it is to a withdrawn standard as is stated in the Certification Directory. The company using the component must either have the component manufacturer resubmit, or have the component reassessed as part of the end product evaluation. The result is, the component recognition is of no value to the new customer even though UL has gone through the work of assuring the component has no shortcomings with regard to the current standard. Apparently UL is reserving the step of updating the paperwork as an income source. - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
