Working Party on General Safety | Session 115 | 9-12 Oct 2018
Geneva
Agenda Item 9. (b)
UN Regulation No. 110 (CNG and LNG vehicles)

GRSG is expected to be informed by the expert from Germany who is leading the Task Force to review the amendments proposed to UN Regulation No. 110 on the basis of ECE/TRANS/WP.29/GRSG/2017/29. Thus, GRSG may wish to consider ECE/TRANS/WP.29/GRSG/2018/16 tabled by Italy, proposing to amend Annex 3A of the Regulation, i.e. the test requirements for the periodic requalification of CNG cylinders to avoid structural failures during their service life, including new provisions for a mandatory impact damage test for all cylinders without the use of shoulder pads.

GRSG agreed to consider in detail a proposal by the Netherlands to insert into the Regulation new requirements for components used in LNG/CNG systems such as the “CNG accumulator” and the “CNG compressor” (ECE/TRANS/WP.29/GRSG/2018/11). GRSG also agreed to revisit a proposal by the Netherlands to allow the use of gas fuelled generators to provide electrical power for accessories or other vehicle systems (ECE/TRANS/WP.29/GRSG/2018/12).

GRSG may wish to consider a proposal (ECE/TRANS/WP.29/GRSG/2018/13) by the International Organization of Motor Vehicle Manufacturers (OICA) to adapt the text of the Regulation to the current technology on the gas flow adjustor in the carburettor or injector.
