Significance and Use
This guide is intended to assist those encountering corrosion or possible corrosion as a causative factor in a failure analysis.
This guide is not an absolute plan that will identify the cause of corrosion in all failure analyses.
This guide is intended to help an investigator identify significant sources and types of corrosion information that may be available for failure analysis.
Appendix X1 contains a checklist that is intended to assist in corrosion-related failure evaluations.
1.1 This guide covers key issues to be considered when examining metallic failures when corrosion is suspected as either a major or minor causative factor.
1.2 Corrosion-related failures could include one or more of the following: change in surface appearance (for example, tarnish, rust, color change), pin hole leak, catastrophic structural failure (for example, collapse, explosive rupture, implosive rupture, cracking), weld failure, loss of electrical continuity, and loss of functionality (for example, seizure, galling, spalling, swelling).
1.3 Issues covered include overall failure site conditions, operating conditions at the time of failure, history of equipment and its operation, corrosion product sampling, environmental sampling, metallurgical and electrochemical factors, morphology (mode) or failure, and by considering the preceding, deducing the cause(s) of corrosion failure.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
