A minor but important correction to the post on Use of alternative Standards: Towards the end of the second-last paragraph a vital “not” was left out. The affected sentence should read “Similarly ASME IX is written to meet the requirements of various standards including ASME B31.3 but does not meet all of the requirements of AS 2885.1.”

The omission has now been fixed on the website but this extra post is for those of you who read the blog via email.
