UL will also post the information for some of the more common standards on 
their web site, including UL 
60950-1<http://www.ul.com/global/eng/pages/offerings/industries/hightech/informationtechnology/dates/609501b/>
 and UL

Once you purchase the standard, all information about this current edition is 
included in the front matter including effect effective dates.  That is, dates 
when it becomes mandatory.

Thanks -doug

Subject: [PSES] Standards Dates


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
