third party PQR range and EN 15614-1 new range

[tufanbora]

Hello,

We did PQR from 5 mm butt weld according to EN 15614-1. Third party wrote 3-6 mm coverage range for fillet weld base metal range. (before standart written 0,5 t (minimum3 mm) to 1.2t. So it is right)

Now standard written 2t for maximum range.

New project I will use this PQR. And I will submit third party PQR approval documents to client.

Which range may I use for this PQR now? As written 6 mm on PQR or 10 mm according to new standard range.

Provided the PQR meets all the requirements of the latest revision of the standard, and all other essential variables fall within the allowable qualification ranges, you can use the wall thickness qualification range in the latest revision of the standard when writing a WPS for the new job.
