Regan, I do not recall a case where a manufacturer completely removed a certification, but I have seen the following scenarios:
1. Where a certification will change, such as from the separate UL and CSA marks to a joined cULus or cCSAus mark. I’ve also seen marks change from one agency to another like TUV:SUD to VDE or TUV Rheinland, etc.. 2. Suppliers will notify us of a change in the standard that a part is evaluated to or the test levels in which a part is specified for. One example I recall is an opto-isolator where the manufacturer re-specified the dielectric strength of the part due to a change in the standard they use. This flagged our R&D department to re-evaluate the part in the application. 3. The most common and recent change we had to deal with is where a supplier first claims their parts to be RoHS-EU compliant. This is usually done without any change to the part number. For us, how do we separate old stock (where RoHS is questionable) from new stock? We had to make sure we used up old stock prior to our declarations of RoHS or purge old stock parts to insure we are using RoHS compliant parts. I hope this was helpful.

That's great you do this. Can you share any examples of where they have removed agencies but still retained the same part #?

We list the certification markings that are on Safety Critical Components on our purchase print as “incoming inspection requirements”. When parts are received, our IQA department visually verifies that the certification markings on the parts match the print. If they are different, the parts are rejected until this issues has been resolved (possible the manufacturer changed the certification body, etc.). 2. The purchase print also has a statement that says that the supplier must notify us in advance of any changes to the part including regulatory certifications and status. The purchase print is a type of contract between the supplier and the purchasing company. 3. Our Compliance Department performs Production Audits (usually on an annual bases) on all families of products. During these audits, all safety critical components are verified that they are what they are supposed to be and verifies the certification markings. The certification markings is also a type of contract or declaration from the manufacturer. Datasheets and pages from the manufacturer’s catalog that shows certification marks, symbols, or a list of standards are really meaningless and as others have already pointed out this information can change without warning.

I have seen some good progress over the years, but I also believe that the industry still continues to eliminate redundant certification (due to standards harmonization) or sometimes complete agency certification (for the sake of cost reduction) on components without changing their respective part number. Or even worse, continue to advertise that the component is approved but in reality, it is not. Has anyone experienced anything recently that they wish to share? P.S. I am updating my old safety presentation and need some good examples before I present again to our local IEEE chapter meeting. Thanks for sharing whatever you can. (privately or within this forum) Cheers!
