For Harmonized standards in the EU, you can get a list of the standards, their various versions, and which expires when.

For UL or CSA standards, how does one tell or determine when a particular version of a standard is no longer usable to show compliance?

Example - I have legacy product approved to UL 60065, 7th Edition but the approval was in 2004 or 2005. Then I have new products approved in 2012. I have seen various ways of listing the standard in different reports.

Typical is this:  UL 60065:2003  R04.04 or UL 60065:2003 R11.06

I have tried to get a straight answer from UL but so far not much help.

Can anyone explain, does UL have expiration dates on standards or a point where they are n o longer usable? I know they send out letters about changes and updates and such, but those never seem to help much and often come at the cost of a file review.

Likewise for CSA. Take CAN/CSA-C22.2 NO. 60065-03 (R2012). Just on their web site and see they show it as: CAN/CSA-C22.2 NO. 60065A-03 (R2012) - Amendment 1:2006 to CAN/CSA-C22.2 NO. 60065-03.

But I don't find anyway to know when my legacy products to older versions of the standards need to be submitted for update.

Kevlar on - I suppose you will tell me I need to review each change and determine it's impact on my product to see if it needs submitted to the agency again. I try to do that, but when you inherit dozens and dozens of legacy products all at once, it can be daunting at the least.

I'm just hoping someone can put a simple explanation to this or that there is an easier way.

All input appreciated and thank you.
Scott
