Could you please define the word “Qualification.” In our understanding, qualification is required for new materials that are not listed in Table A.2 of NACE MR0175/ISO 15156-2. We would like you to confirm that our interpretation is correct and if not what is your position?
Table A.2 of ISO 15156-2 gives examples of materials that can be qualified provided they comply with Paragraph A.2.1. If not listed in Table A.2, materials must be assessed in the terms of the requirements given in Annex A as explained in Paragraph 7 of Part 1. Again it is up to the equipment user to decide if materials need further qualification through testing or field experience as explained in Paragraph 8 of Part 1.
This question is in relation to NACE MR0175/ISO 15156-2 Annex A Table A.2
