31. The expert from Canada gave a presentation on high pressure cylinders for the on-board storage of natural gas as a fuel for motor vehicles (GRSG-106-29). He underlined the need to harmonize worldwide the test requirements for the CNG containers and proposed to align the provisions of Annex 3 to UN Regulation No. 110 with those of standard ISO 11439:2013. He added that GRSG should also consider simply inserting into Annex 3, references to ISO 11439. GRSG noted the decision of WP.29 that a reference in a UN Regulation to a private standard should not be adopted without free availability of that standard (see report ECE/TRANS/WP.29/1108, para. 39). The expert from OICA questioned the relevancy of the ISO standard, if all provisions were included into the UN Regulation. The Chair invited the gas experts to prepare an official document for consideration at the next GRSG session. The secretariat was requested to keep GRSG-106-29 on the agenda as a reference document. |
