In the absence of complete harmonization with ISO 11439, this proposal recommends that Table 6.4 of UN R110 should be amended by the following for CNG-1 designs:
Delete A.17, A.25, and A.7 since they do not match the tests specified in paragraph 7.5 on Cylinder design qualification tests
Add A.15 and A.6 since they do match the tests specified in paragraph 7.5 on Cylinder design qualification tests
Add A.24 because paragraph 6.9 on Fire protection requires all PRDs on all cylinder types to comply with A.24.
This proposal (WP.29/2018/153) was adopted by the World Forum. Forty Contracting Parties out of the 50 applying UN R110 were present for the vote by AC.1. Forty voted in favor with zero against and zero abstaining.
