ERRATA - API Std 521, Pressure Relieving and Depressuring Systems

American Petroleum Petroleum (API) released the API Std 521, Pressure Relieving and Depressuring Systems early of 2007. As usual, there are some mistakes spotted in the this Standard. First errata that i received was dated June 21, 2007. I am a bit outdated. Somehow, i guess there are still many engineers out there (like me...) may not aware of the release of this errata. If you are user of this standard, i strongly urge you to download this errata and make correction to your copy.
