Hi all am new to the site and relatively new to inspection work.

Am reviewing some procedures for a new job I am due to go on tomorrow (only been given them all today)

Have noticed that they are using BS EN ISO 17637:2011 in all their procedures, this has since been replaced by 17637:2016.

My query really is, at what point does it become mandatory for them to change to the new ISO. Obviously it seems to me that you should be using the most up to date of the ISO if that is what your referencing.

No worries if nobody knows just wanted peoples opinions before I bring it up in the meeting tomorrow.
