Dear Mr. Burckhardt, Thank you for your lucid explanation of the standards amnmendment process. I have run into these problems on a regular basis.
When I order a document, I want to order EN 60950 in it's current version with any and all amendments included. I don't know what they are and don't always care, just so I get the latest thing. Optionally, I want to order some specific document such as A1 or A2 or whatever. That is when I know precisely what I need and can save some money by ordering a 10 page amendment to a 200 page standard. The hard part is that I do not always know what I want (need) but just that I want (need) it. One thing we could all use is a single place to go and find out what is the original edition, and what amendments, supplements and corrigendums exits for that base document. I have even asked test houses and agencies like TUV and UL and could not get reliably accurate information. In many cases they are just like the rest of us, all they know is what they have in their hands. Every document published, whatever it is, should have a paragraph in the front that says what is included and not included and what this particular document is designed to replace. That way, I can see the new and from it can determine what is old and can be tossed out. The statements I have read in some standards and amendments are not clear enough as to what I can toss out and what I need to go along with what I have in order for me to have something useable and current. Off my soap box for now. Thanks again for your great explanation. Regards, Scott Douglas [email protected]
