The method has gone through the round robin phase and internal committee review and is now open for public review. I invite the members of the ValidNMR community to review this draft standard and comment on it through the following link:

The opportunity for review will remain open until July 17, 2021. You will have to register using your e-mail address and create a password. 

I look forward to your comments on this.

Ian Burton.
