Proposal for discussion to enable the certification of CNG compressor components. Due to density and temperature constraints, LNG fuel systems require technologies to warm the LNG fuel to reach temperatures and pressures suitable for the engine. In some configurations, this involves the use of CNG compressors. Therefore, this proposal seeks to enable use of this technology through establishment of requirements to ensure safety.

Proposal to clarify the test procedure to be applied in assessing compliance with the requirement for “compatibility with heat exchange fluids of non-metallic parts” Annex 5Q is part of UN Regulation No. 110. In Annex 4D, the wording “Compatibility with heat exchange fluids” is used but there is no reference to the applicable tests. The proposal clarifies that the “LNG heat exchanger – vaporizer” falls within Annex 5Q. The proposal correspondingly clarifies the general overview Figure 1-2, with all tests from Annex 5, and Table 5.1 in Annex 5.

Request by the VRU-Proxi informal group for data on close proximity maneuvering collisions with vulnerable road users.

Question of possible certification under UN Regulation No. 46.04 for an indirect device class I (interior mirror) acting as a taximeter.

Proposal to correct document GRSG/2016/20 where the reference to “Annex 5, paragraph 4” should be to paragraph 3.

Proposal to correct document GRSG/2017/15 based upon comparison against GTR No. 6. The table being revised is in Annex 18 (not 21). This proposal further corrects several values in the table per the original table developed under GTR 6.

Proposal to correct the omission of Class VII devices from the communication form described under Annex 3 of the regulation.

Updated proposal to correct the omission of Class VII devices from the communication form described under Annex 3 of the regulation.

1. Document GRSG/2017/22 proposed by Turkey raised concerns regarding the location on the vehicle of the filling unit and a limitation of the service life of LPG containers
2. In order to prevent a proliferation of different service-life specifications, AEGPL proposes a fixed mandatory service live of 10 years.

Presentation on awareness of vulnerable road users proximity.

Proposal to require marking of extension numbers on accessories relevant to the UN R67 bonfire test (e.g., multivalve, pressure relief valve, pressure relief device) in order to prevent/prohibit the misuse (in container configurations) of these accessories. The proposal includes provisions for components where such marking is impractical based upon text drawn from UN R46.

Proposal to harmonize the requirements for CNG/LNG vehicles under UN R110 with those of the international standard ISO 11439:2013.

Proposal to harmonize the requirements for CNG/LNG vehicles under UN R110 with those of the international standard ISO 11439:2013.

Proposal to delete footnote ¹⁸ of Table 1 regarding telltale no. 1 (Master lighting switch) when it is combined with telltale no. 19 (Position, side marker, and/or end-outline marker lamps). The footnote is redundant and potentially confusing since UN R121 already refers to paragraph 5. of ISO 2575-2004 which states, “A given symbol may be shown in more than one of the colours specified in 5.1 in order to convey a change in the operating condition.”

Proposal to insert Footnote 18 for Tell-tale 1 (Master lighting switch) stating, “Symbol may be shown in other colours than specified in column 5 in order to convey different meanings according to the general colour coding as proposed in paragraph 5. of ISO 2575-2004.”
