Proposal to apply a minimum burst pressure (BPmin) in place of the current COP that only requires the manufacturer to provide mid-burst pressure with specified variation. The proposal also deletes the phrase “and in no case less than the value necessary to meet the stress ratio requirements” which was erroneously copied into the regulation.

Proposal to correct a reference in UN R134, Annex 3, paragraph 3.4. The reference to paragraph 6.2.2.2. was transposed from GTR No. 13; however, it ostensibly refers paragraph 2.2 of Annex 3 in UN R134.
