You have to pay for UL/CSA/IEC/NFPA etc. standards.
If your corporation is serious about making safe, commercial products, then this is not a problem.
Canadian public libraries offer the CSA Standards Database under digital content section.
But you do not get (download) a PDF that can be printed (as I recall), or used anywhere else but with that library card- it's a secure PDF requiring the File Open plugin; which can be found here:
http://plugin.fileopen.com/all.aspxIt's a hassle and much pain to eventually look at a secure PDF after getting handed off to the CSA database. That website is slow and not always working properly.
But terrific to see the latest standards and notification, errata etc.
With the on-going harmonizing of UL/CSA/IEC standards, sometimes you get lucky and find the UL equivalent.
