Test Requirements for Reinstating Service Lines (17.6)
Criticality: Medium Progress: Addressed, Not Adequately Score: 12 DOT Relevance: §192.725
Description of Key Area
Section 192.725 (Test Requirements for Reinstating Service Lines)
of Subpart M (Maintenance) of 49 CFR 192 states, “…each disconnected service
line must be tested in the same manner as a new service line, before being
reinstated.”
Discussion of Criticality
Rules regarding testing of disconnected hydrogen service lines
and hydrogen service lines temporarily disconnected from the main must be
formulated. Also, rules must be made regarding the need to test bypass line
installations on hydrogen service lines. There may be additional considerations
for higher pressure capable materials and structures that have not yet been
identified.
Discussion of Progress
This topic will be addressed by ASME B31.12.
Recommendations
Standards for test requirements for reinstating services must be
established and incorporated by reference into the federal code.
