Hello:
The U.S. Hazardous Materials Regulations (HMR) (at 49 CFR Parts 171–180) incorporate by reference the 1998 edition of the ASME Boiler and Pressure Vessel Code (BPVC), which has now been superseded by several updated editions. The HMR primarily affects the design, manufacture and repair of cargo tanks.
See § 171.7(g) at:
The HMR continues at:
This incorporation by reference of the 1998 BPVC has been in place for quite some time now. Each new edition of the BPVC, of course, is required for ASME Code work, starting 6 months after the edition is issued, which conflicts with the HMR.
I'm trying to determine what effect, if any, the HMR reference to an outdated BPVC has on the actual practices of cargo tank makers. Would anyone who designs cargo tanks, or has done so in the past, care to share their thoughts or observations?
Thanks so much,
Sean Streiff
