Requalifying UN Specification Cylinders 06/12/2006
In this final rule, PHMSA is amending the Hazardous Materials Regulations (HMR) to adopt standards for the design, construction, maintenance and use of cylinders and multiple-element gas containers based on the standards contained in the United Nations Recommendations on the Transport of Dangerous Goods. Aligning the HMR with the international standards promotes greater flexibility, permits the use of advanced technology for the manufacture of pressure receptacles, provides for a broader selection of pressure receptacles, reduces the need for special permits, and facilitates international commerce in the transportation of compressed gases without sacrificing the current level of safety and without imposing undue burdens on the regulated community.
