Hi
in lots of our technical documents regarding the material of the specification of the material to be used in sour system phrases like "according to NACE Mr0175" or "NACE compliance" is being used, and unfortunately it causes lots of problem for us.
So I appreciate if any body could help me to know what exactly these phrases mean and what kind of tests and specifications are required based on ISO 15156 (NACEMR0175).

thanks in advance
