Question: Using NACE MR0175-ISO 15156-1, Clause 5, Paragraph 9 and NACE Interpretation MP INQUIRY #2009-05 Part 1 as references. Based on the fact that most metal rupture discs are plastically deformed during manufacturing and all metal rupture discs plastically deform when they burst, are metal rupture discs outside of the scope of NACE MR0175-ISO 15156?
Answer:
No. Permitted exclusions are listed in ISO 15156-1 Table 1. When ISO 15156 is specified, components, including rupture discs, must comply with the materials and conditions listed in the standard or qualified in accordance with Annex B.
This question is in relation to NACE MR0175/ISO 15156-1 Clause 5
