Applicable Test Methods The test methods are not equivalent and each can have a specific role. Method A indicates the fitness for service of a specific material in the given environment (see Appendix 1). Methods B and C are principally used to rank the performance of several materials in a given environment (see Appendix 2).

Such specimens should not be flattened prior to testing. 7 Evaluation By agreement prior to contract and start of production, the purchaser may specify evaluation by metallographic a n d / o r ultrasonic methods. Metallographic evaluation shall comply with NACE TM0284 with the additional requirement that all faces shall be subjected to either wet magnetic particle testing or macroetching before final metallographic polishing, in order to make an accurate assessment of whether any significant cracks are present which may have become invisible due to smearing of the metal surface during preparation.
