Question: Can you confirm our company’s interpretation of the testing described in ANSI/NACE MR0175/ISO 15156-3:2009 Annex B, Section B.8? Our interpretation is that the GHSC testing described in B.8 is for qualification of CRA’s for H2S-service by laboratory testing; this testing in B.8 is qualification testing for including the CRA in the standard and it is not intended to be routine/quality control testing that must be performed on every heat of CRA that is produced at a mill.
Section B.8 defines the additional requirements/changes to SSC testing for GHSC testing. There is no implied limitation on the application of these tests. The type of tests and the frequency of “periodic” testing to confirm the resistance to cracking for quality control purposes is not defined in ANSI/NACE MR0175/ISO 15156-3 and, these tests, if required, shall be agreed between the manufacturer and the purchaser. The subject of production route qualification is covered in Section B.2.3 “Qualification of a defined production route”.
This question is in relation to NACE MR0175/ISO 15156-3 Annex B B.8
