WPS & PQ for HDPE welding

[psgo]

Good afternoon,
I am currently working on a power plant project which is being constructed to ASME B31.1.

Before HDPE welding, Client request WPS, Operator Qualification Test, and Procedure Qualification Record for HDPE welding.
1. What code should be applied to Procedure qualification for HDPE welding?
2. What kind of test method should be applied to Operator Qualification Test?
Please, anyone who has experience in HDPE welding would be appreciated.

Most of the manufacturers have their recommended procedures you can down from their websites.
