Question: For HIC test, NACE MR0175/ISO 15156-2, Table B.3 is not clear regarding the acceptance criteria to be taken into account. We usually understood that “CLR, CTR, CSR” to be taken into account is the average of the values measured from one test specimen as defined in NACE Standard TM0284, Paragraph 4.2.1. What is your position?
ISO 15156-2, B.5, Paragraph 3 makes clear that where no requirement is given NACE TM0284 shall be followed.
This question is in relation to NACE MR0175/ISO 15156-2 Annex B Table B.3
