Techstreet Enterprise e-mailed me today that a redline of the original release of API 521 on 5/31/2022 is available as of 11/1/2022.

I skimmed through the entire document. It is highly red- (deletions) and blue- (modifications and additions) lined! I recommend folks download it and start using it.

ok, thanks and interesting.

as far as the usage, we all know it depends upon contractual agreements for EPC & other work. Regardless, a wise client should review and update corporate standards & specs accordingly.
