Test conditions for evaluation of pipeline and pressure vessel steels. Compares test results from different laboratories of the absorption of hydrogen generated by corrosion of steel in wet H2S.
Provides a standard set of test conditions for consistent evaluation of pipeline and pressure vessel steels and compares test results from different laboratories pertaining to the results of the absorption of hydrogen generated by corrosion of steel in wet H2S. Describes two test solutions, Solution A and Solution B, and includes special procedures for testing small-diameter, thin-wall, electric-resistance welded and seamless line pipe. Test is intended to evaluate resistance to hydrogen-induced (stepwise) cracking only, and not other adverse effects of sour environments such as sulfide stress cracking, pitting, or weight loss from corrosion. Complements NACE MR0175/ISO 1556. Key words: steel pipelines, sulfide stress cracking
NACE external corrosion direct assessment (ECDA) process — assessing and reducing the impact of external corrosion on pipeline integrity.

HISTORICAL DOCUMENT. Specification, selection & use of sensors for monitoring atmospheric corrosion. These sensors - based on electrochemical techniques - provide continuous records of contaminants, corrosion rates, or coating condition.
The Bresle patch method is defined by ISO 8502-9. This standard establishes the equivalence of other methods for measuring the level of contamination of salts to results of that same Bresle patch method.
