Who is responsible for certification of materials and equipment to NACE MR0175? The manufacturer or the user?

At OGC Energy we frequently receive questions about the certification of materials and equipment to NACE MR0175. This is why we prepared a short webinar on the basics of certification to NACE MR0175 and how we are helping clients to solve some of these challenges.

Certification can be a challenging topic and we have helped clients answer some of these questions:

  • Who is responsible for certification?

  • Our material is certified to NACE MR0175 2009 and our client needs certificates to 2015, what can we do?

  • How can a raw material (steel) manufacturer certify a material if they do not know the final application and its conditions.

  • Our material does not state “Certified to NACE MR0175”, can it be used in sour service?

Is it the intent of NACE MR0175/ISO 15156-2 that material manufacturers state on the Material Test Certificates that material conforms to the NACE standard even though no operating criteria are known?


Certification requirements are outside the scope of the standard and there are no stipulations concerning certification in NACE MR0175/ISO 15156.

The compliance with the NACE/ISO standard of a material for use in H2S-containing environments in oil and gas can only be assessed for the material in its final product form and this may differ metallurgically from that of the material supplied by the materials manufacturer. In addition, compliance with the standard also depends on the cracking mechanisms that have to be considered.

NACE MR0175/ISO 15156-2, Clause 9, Annex E (Informative) and NACE MR0175/ISO 15156-3, 7.2, Annex C (Informative) make some suggestions on how materials manufacturers and other suppliers might mark their materials to indicate the evaluation (testing) that they have carried out.
