HI All,

I'm working on reviewing my site's WPSs' for code(s) of construction and site engineering speciation's updates, basically we have WPSs' from the 80s to the present which technically don't expire however the code(s) of construction and our own site eng specs have changed over the past 30 years thus requiring a compliance review with potential for administrative updates and/or requalification.

We've got a healthily selection of Cr WPSs' which it seems the P-No used to be only P5... now looking at the PQRs the materials used have now been split from P5 into P5A, P5B and P5C... I'm curious when this change occurred. 

The though process is (if no requalification is required) to use the original PQRs from the 80s completing an administrative update to the WPS outlining the current assigned P-No.. Has anyone previously dealt with this? What are your thoughts, is this the best approach or do you have a suggestion of how you would tackle this?

Note:
This is my first post feel free to share WPS review items and elaborate on personal experiences.  

Best,
Paisley Natalia
