Introduction

This page provides an answer to a question regarding the interpretation of testing described in ANSI/NACE MR0175/ISO 15156-3:2009 Annex B, Section B.8. The inquiry seeks confirmation on whether GHSC testing is for qualification of CRA’s for H₂S-service by laboratory testing and if it is not intended to be routine testing performed on every heat of CRA produced at a mill.

Answer

Section B.8 does define additional requirements/changes to SSC testing for GHSC testing, but there is no implied limitation on the application of these tests. The type of tests and the frequency of periodic testing for quality control purposes is not defined in ANSI/NACE MR0175/ISO 15156-3. If required, such tests 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.””
