Criticality: High Progress: Addressed, Not Adequately Score: 20 DOT Relevance: §192.501 – §192.517
Description of Key Area
Material 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
Burst testing is one mechanism to verify design parameters and
assumptions.
Discussion of Progress
SRNL recommends that mechanical tests for materials to be used
for hydrogen service include burst testing.
Recommendations
Burst testing as a topic is not covered in ASME B31.12. Standards
for burst testing of materials and structures to be used for hydrogen pipelines
should be established and incorporated by reference into the federal code.
