You can't write a WPS based on the ISO 15614 PQR. however you may use both WPS/PQR from other standards, provided the designer takes the responsibility based on the specific structure or service conditions or both (refer para 4.1.1.2 of AWS D1.1). alternatively you can use SWPS provided in AWS D1.1 as prequalified procedures.

Subject: Comparision between ISO15614 Part 1 and AWS D1.1 PQR requirements
Hi Raghu,
Could you please advise on “comparison between ISO15614 Part 1 and AWS D1.1 PQR requirements”.
Also can a WPS be as per AWS D1.1 and PQR be as per ISO15614 Part 1?
Am not able to post this on blog.
