In December 1996, the United States Department of Transportation requested that ASME create a new code for transport tanks. ASME formed Subcommittee XII to fulfill this request. The scope of the subcommittee is the development of codes and standards covering the construction, in-service inspection, alteration and repair of transport tanks used for the carriage of dangerous goods by all means of transport; to develop criteria for accreditation of manufacturers of these tanks; and to develop codes and standards that are suitable for reference by regulatory authorities and safety organizations world-wide. Some significant code issues are the separation of technical and administrative requirements, third-party inspection, minimal impact on the industry’s current way of doing business, and the technical issues associated with pressure relief for vessels that can overturn. The first edition is in the hands of ASME Technical Publications and is scheduled to be issued in late 2003.
