The current version of NORSOK M-601:2016 Welding and inspection of piping, was published 29  April 2016. To ensure that the standard holds sufficient quality, it is important to assess the need for revision on a regular basis. Standards Norway is now requesting feedback from the users of the standard about whether it should be confirmed for another five years, or if it should be revised or if it should be withdrawn from the market.

Attached is a pdf file showing the standard's table of contents, scope and normative references.

If the conclusion is to revise the standard, inputs from the users on topics that need corrections, additions, or revision are highly valuable, as well as nominations of experts from the industry that are interested in participating in the revision team.
