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:

1. 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
2. Add A.15 and A.6 since they do match the tests specified in paragraph 7.5 on Cylinder design qualification tests
3. Add A.24 because paragraph 6.9 on Fire protection requires all PRDs on all cylinder types to comply with A.24.

Proposal to modify the type-approval certificate as specified in Annex 2B by introducing additional points:

1. Type (point 2-type of equipment)
2. its version (point 3)
3. variant (point 4) and pressure classification
4. (point 5 – include the component’s working pressure for class 0)

Proposal to require labeling of products with the designation of the version, variant and the number of type-approval certificate extension based on which the product was approved for sale in order to ensure linking of the technical documentation with the product designation and to improve the ability to verify the design of the components.

Proposal to delete “trade name” from the approval definition in order to avoid strict interpretations where a manufacturer would be obliged to define a new container type designation whenever the tank’s trade name is updated (whereas the trade name is inconsequential in terms of product approval).

Discussion of the evolution of UN R73 with a proposal to update load requirements for lateral protection devices:

• Application of a force of 3kN perpendicular to the device (as currently defined)
• Max. strain under loading at 90mm over the 250mm most rearwards part
• Max. strain under loading at 450mm on the other parts.

Proposal to amend geometrical criteria and installation provisions for lateral protection barriers in order to improve their performance with regard to vulnerable road users (e.g., lateral contact with a motorcycle or its rider(s)).

Proposal to update the horizontal static force requirement for lateral protection devices to 3 kN and the deflection under load criteria to 90 mm over the rearmost 250 mm of the device and 450 mm over the remainder of the device. The purpose is to reduce the risk of running over a person (e.g., a motorcycle rider) during a lateral collision.

Proposal to introduce requirements for color contrast for signage and provisions for passengers with limited mobility. At its previous session (GRSG-112), GRSG approved a proposal by Germany (GRSG/2016/20) as revised in document GRSG-112-35 with the proviso that OICA would prepare a final document including transitional provisions for consideration at GRSG-113. Based upon the new general guidelines developed for Revision 3 of the 1958 Agreement, the new requirements would transition into application from September 2020 for new types of vehicles and September 2022 for all existing types.

Proposal to align UN R43 with values in GTR No. 6 and UN R125 with regard to the aiming positions of the driver’s eyes.. This document complements and completes the proposal in document GRSG/2017/15.

Proposal to clarify the camera monitor provisions with regard to the use of image overlays. The current English text can be interpreted to allow overlays only when the vehicle is moving in reverse. In particular, this resulted in an unambiguous translation into French allowing overlays only when the vehicle is in reverse gear. The original intent was to limit overlays to rear views of the vehicle regardless of the moving vehicle direction. Therefore, this proposal clarifies the English and French texts.

Alternative solution from OICA to the German proposal GRSG/2017/16 regarding visibility/access requirements for PRV/PRD-related components in order to improve maintenance and reduce the risk of critical failures of pressure relief devices.

OICA proposal of modifications to the Turkey proposal to insert new provisions on the location on the vehicle of the filling unit, marking of the LPG container date of production, and a limitation on the maximum service life of LPG containers to 15 years. Given that the risks concern containers located outside and under the vehicle, OICA proposes focusing discussion of the 15-year service life on such containers. In addition, the proposal would introduce new requirements and therefore would require transitional provisions.

Proposal to improve provisions for the visual inspection of CNG cylinders, LNG tanks, and their accessories. Germany has proposed (document GRSG-112-33) the prohibition of components or parts of protective housing which must be disassembled during inspection. Italy has proposed (document GRSG-112-28) that visual inspection of cylinders Include access inside any protective covers of the cylinders. Based upon field experience, OICA believes that corrosion damage between support straps, brackets, and pads and the cylinder can be readily identified during visual inspection. Such corrosion requires cylinder replacement. Therefore, OICA proposes clarifications to inspection procedures to address the German and Italian concerns.

Proposal to include transitional provisions for the alignment of UN Regulation No. 110 with ISO 11439:2013 per document GRSG/2017/31.

Proposal to delete references to European standards for radio transmissions (paragraphs 6.2.3., 7.2.3. and 8.2.2.). Manufacturers must comply with legal requirements established by local authorities around the world. Therefore, the references to European norms present one instance of local requirements rather than an international set of agreed requirements.

Proposal for further discussion concerning technical advances in the use of CNG accumulators as an intermediate technology for promoting high, stable pressure in CNG engine injection systems. The CNG accumulator is used to stabilize the gas pressure and to allow engine operation whenever the LNG supply system is not able to deliver fuel. This proposal would define requirements to enable the certification of these components.

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.

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.

Proposal as amended following GRSG discussions to clarify the camera monitor provisions with regard to the use of image overlays. The current English text can be interpreted to allow overlays only when the vehicle is moving in reverse. In particular, this resulted in an unambiguous translation into French allowing overlays only when the vehicle is in reverse gear. The original intent was to limit overlays to rear views of the vehicle regardless of the moving vehicle direction. Therefore, this proposal clarifies the English and French texts.

Revised proposal to introduce requirements for color contrast for signage and provisions for passengers with limited mobility. Based upon the new general guidelines developed for Revision 3 of the 1958 Agreement, the new requirements would transition into application from September 2020 for new types of vehicles and September 2022 for all existing types.

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

Explanatory information, revised for discussion during the 113th GRSG session, from the AECS informal group regarding the provisions in document GRSG/2016/19 for the new UN Regulation on automatic emergency call systems.

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 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 as approved by GRSG to introduce requirements for color contrast for signage and provisions for passengers with limited mobility. Based upon the new general guidelines developed for Revision 3 of the 1958 Agreement, the new requirements would transition into application from September 2020 for new types of vehicles and September 2022 for all existing types.

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

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.”
