The WSAA Codes and Appraisals Group have met and included within their Agenda was a joint meeting with Mark Heathcote from PIPA to discuss the status and feedback relating to the recently introduced WSAA specification amendments to BRT procedures for AS/NZS 4130 PE pipe production. 

The outcome was that WSAA’s specifications were amended to extend the maximum frequency for OIT testing from 12 hours to 24 hours.

The revised Clause in WS PS 207 and WS PS 215 is now:

Clause 2 (c)

The manufacturer’s quality plan shall include within their  batch release test procedures a thermal stability test to ISO 11357-6 to be completed on a sample taken from the inside surface of the first pipe manufactured in a batch of a particular DN and PN and at an ongoing frequency not exceeding 24 hours of production for that pipe batch or when a new raw material compound is introduced.
