Testing

Originally, test methods for sour service such as NACE TM0177 (SSC) and NACE

TM0284 (HIC) were developed to provide

QA/QC methods using laboratory test environments, which were formed to aggressively identify materials suscep- tible to damage. Now, the industry seeks to reduce the excessive conservatism this approach imposes and the assessment of corrosion resistant alloys has increased.

Therefore, more application-speci? c testing has been undertaken to simulate operating conditions.
