ASTM F519 Hydrogen Embrittlement Test (14.1)

Criticality: High
Progress: Addressed, Monitoring
Score: 10
DOT Relevance: §192.501 – §192.517

Description of Key Area

Hydrogen pipe embrittlement testing falls under Subpart J (Test Requirements) of 49 CFR 192. Per the Code, “This subpart prescribes minimum leak-test and strength-test requirements for pipelines.”

Discussion of Criticality

An ASTM standard (ASTM F519) has been created to provide for hydrogen pipeline embrittlement evaluation.

Discussion of Progress

As this is a relatively new topic, even though an ASTM document has been established, the subject should still be monitored.

Recommendations

Once the adequacy of ASTM F519 has been evaluated against the ongoing embrittlement research, the established standard should be incorporated by reference into the federal code.
