Proposal from the Netherlands in order to enhance the objectivity of the requirements for camera monitor systems in Regulation No. 46 on devices for indirect vision.

Proposal from the Netherlands to amend UN R67 in order to permit approval of higher pressure LPG direct injection components like the fuel pump, the fuel rail, the injectors and a safety valve leading back fuel from the high pressure parts to the fuel tank.

Revised proposal prepared by the Informal Group on Camera-Monitor Systems to permit the replacement of all mirrors by camera-monitor systems, taking into account comments received during the 101st and 102nd GRSG sessions.

Proposal to clarify the text concerning automatic valves in the draft Supplement 1 to the 01 series of amendments to Regulation No. 110 (document WP.29/2013/101).

Proposal to extend the scope of UN Regulation No. 118 to vehicles powered by compressed natural gas (CNG).

Proposal to introduce a new class of CNG components (Class 6) operating at a higher pressure.

Text prepared by the Netherlands and the International Association for Natural Gas Vehicles (IANGV/NGV Global) to clarify the provisions of Chapter 18 following the introduction of automatic valves (see report GRSG/84, para. 38).

Proposal by the Informal Group on Camera-Monitor Systems (IGCMS-II) to introduce the optional replacement of mirrors of Classes I to IV by camera-monitor systems.

Proposal to correct the numbering of chapter 18 following the introduction of provisions for automatic valves.

Proposal to regulate the direction of discharging the pressure relief devices of CNG containers.

Proposal to align UN Regulation No. 10 with the proposed amendments to Regulation No. 46 (document GRSG/2015/2) to enable the replacement rear-view mirrors by camera-monitor systems. This proposal is also subject to the consent of the Working Party on Lighting and Light-Signalling (GRE).

Proposal to treat camera-monitor systems the same as rear-view mirrors under UN R26 in view of the amendment to UN R46 to enable the replacement of rear-view mirrors by CMS (i.e., document GRSG/2015/2).

Proposal to ensure that all devices for indirect vision, including exterior cameras, are covered by UN R61. This proposal is part of a package of proposals to update various regulations impacted by the proposed amendment to enable the replacement of rear-view mirrors by camera-monitor systems.

Proposal to adapt UN R79 in line with the proposed addition of camera-monitor systems to UN R46 (indirect vision). UN R79 refers to external mirrors in test procedures involving the vehicle turning circle. This proposal replaces the reference to mirrors with a broader reference to “indirect vision devices” that includes CMS.

Proposal to align UN R94 with the draft amendment to add camera-monitor systems to UN R46 (i.e., document GRSG/2015/2). Under UN R94, the measurement for the 40% overlap between the vehicle and crash barrier excludes external rear-view mirrors. This proposal would extend the same treatment where the mirror has been replaced by an exterior camera.

UN R107 includes a provision to prevent a folding seat used by the crew from obstructing the view of the exterior rear-view mirror. In light of the proposed amendment to introduce camera-monitor systems into UN R46 (indirect vision), this proposal would extend the same treatment to CMS used in the place of rear view mirrors.

Proposal to allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone. Currently, non-seamless double and single wall tubes are used in brake and fuel tubing applications, allowing for the use of a variety of end forms and coupling techniques. Provided the tubing can withstand the applicable tests according to Annex 15, Table 1, such configurations should be permitted under UN R67 in order to remove an unwarranted design restriction.

Proposal to allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone. Currently, non-seamless double and single wall tubes are used in brake and fuel tubing applications, allowing for the use of a variety of end forms and coupling techniques. Provided the hose assembly can withstand the impulse test of paragraph 1.7. and the tests of Annexes 5A (overpressure test) and 5B (external leakage test), such configurations should be permitted under UN R67 in order to remove an unwarranted design restriction. In cases where a soft seal body (e.g. O-ring) is used, the compatibility of the material with use conditions must be demonstrated by testing according to Annexes 5D (CNG/LNG compatibility test), Annex 5F (resistance to dry heat) and Annex 5G (ozone aging).

Proposal to correct a typographical error in paragraph 7.1. where the reference should be to paragraph 8.22 rather than 8.21, to remove a duplicate and contradictory reference in Annex 4A to the requirements of Class 1 pressure relief valves, and to align paragraph 2.2. of Annex 4H with paragraph 18.6.1.2. limiting the delay in switching-off of the automatic valve after stalling of the engine to two seconds (rather than five as presently in the text).

Proposal to include the liquefied natural gas (LNG) fuel connector provisions as specified in ISO 12617:2015.

Proposal to establish procedures for the approval of non-seamless double and single wall gas tubes provided they can withstand the applicable tests according to Annex 15.

Proposal to correct the definition of “manual valve”, including deletion of the phrase “rigidly fixed to the cylinder or tank”. The definition of the manual valve as part of the accessories fitted to the container or tank (para. 4.16.) is different from the definition specified in paragraph 4.22. The proposed editorial change aims at clarifying the text of these definitions.

Proposal to establish procedures for the approval of non-seamless gas tube(s), gas tube(s) made of materials other than copper, stainless steel, and steel with corrosion-resistant coating, and their couplings in Liquefied Petroleum Gas (LPG) vehicles provided they can withstand the applicable tests according to Annex 15.

Proposal presented as an alternative to the previous proposal from Poland (GRSG/2017/10) to require manufacturers to mark the approval extension number on any accessories relevant to the bonfire test (multivalve or, when approved separately, pressure relief valve (discharge valve) and pressure relief device) so that the fitting of any accessory not on the list of approved configurations (Table 3 in the appendix of Annex 2B) will be prevented/forbidden. This solution would imply a new requirement in Annex 2A for the marking of the accessories fitted to the containers.

Proposal to introduce requirements for CNG compressor and CNG accumulator components designed to maintain stable pressure in fuel systems.

Proposal to allow the use of a generator fueled by the vehicle gaseous fuel system that provides electricity to run accessories (e.g., overnight power in sleeper cabs, to maintain battery charge during high electrical power use with loading or lifting equipment). This proposal would allow for the use of LNG/CNG from vehicle fuel tanks and thereby reduce the potential need to vent gas into the air in response to pressure buildup due to warming over time by using the gas to power other devices and equipment.

Proposal to update vehicle-fuel identification symbols in alignment with ISO 17840-4, Part 4 (Propulsion energy identification) and to extent the scope of the fuel identification requirements to include N₂ and N₃ vehicles.

Proposal to update the vehicle-fuel identification symbols in line with ISO 17840-4, Part 4 (Propulsion energy identification) and to extend the scope of the identification requirements to N_/2 and N₃ vehicles.

Proposal to apply the same tell-tale requirements for tyre pressure refill systems (TPRS) and central tyre inflation systems (CTIS) as already in place for tyre pressure monitoring systems (TPMS)

Proposals to update the existing requirements for compressed natural gas/liquified natural gas (CNG/LNG) fuelled components.

Proposes the addition of design qualification tests also will harmonize with ISO 15500-13:2012, and the North American CSA/ANSI PRD 1 (2020).

Update paragraphs to be in line with the requirements of ISO15500 and NGV3.1 (industry standards for CNG).

Proposal to clarify the need to have a support device for centre axle trailers, independent of the type of coupling device.

Proposal to update the references to the three-dimensional H-point (3-D “H”-point) measurement and calibration procedure pursuant to the update of the device specifications and transfer from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1 (M.R.1).

Proposal to update the references to the three-dimensional H-point (3-D “H”-point) measurement and calibration procedure per the update and transfer of the device specifications from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1 (M.R.1).

Proposal to update the references to the three-dimensional H-point (3-D “H”-point) measurement and calibration procedure as moved from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1 (M.R.1).
