Proposal for new safety provisions with regard to LPG systems having hydraulic interconnections with the petrol or diesel fueling system through which inter-flows of fuels may occur.

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 require, in instances where ogive protective covers are fitted to a cylinder, that the covers be removed before conducting the impact damage (drop) test.

Proposal to harmonize the requirements on Compressed Natural Gas (CNG) and/or Liquefied Natural Gas (LNG) vehicles of UN Regulation No. 110 with those of the international standard ISO 11439:2013.

Proposal to clarify the test requirements in alignment with the French text of the regulation by amending paragraph 5.10 to read “There shall be no protruding parts, sharp edges, etc. near the installed tank likely to increase the risk of damage on the tank in the event a collision to the front, the side or the rear of the vehicle.” (Modified text in bold)

Proposal for editorial corrections to align the definition on plastic glazing between the original English version and the French translation as well as of the communication annex on principal/secondary characteristics for laminated-glass windscreens.

Proposal to add a telltale and symbols for “Accident Emergency Call System (AECS)” and to align UN R121 with the 07 series of amendments to UN Regulation No. 16:

1. the term “seat belt” is replaced by “safety belt”,
2. the symbol for safety belt, defined in item 21 of Table 1 in the Regulation, may be displayed in different colours to convey different meanings. Therefore, the existing footnote 18 has been added to item 21, and
3. this symbol may be replaced by different symbols for seats other than those of the front row. Therefore, a new footnote 22 is added to item 21.

Proposal to correct the scope of the GTR to align with Part A of the GTR, UN R43, and regional/national interpretations and to align the impact test procedure description with that of UN R43 and ISO 3537. The scope is amended to add “panes or as partitioning” while deleting the wording “use of double windows panes, each pane is considered a separate item of glazing panes”. The impact test procedure is clarified to define the point of impact with reference to the test piece (not the current “supported area”) and within 25 mm of its geometric centre and 50 mm of its centre.

Proposal to align the headform test with the deceleration measurement and the test of resistance to abrasion with ISO 15082:2016-11, including changes to the test details, correction of the headform calibration values, and the introduction of abrasion reference materials. The latter is combined with an abrasive-wheel qualification and a correction calculation (for plastic materials only).

The proposal also amends Figure 2a of Annex 21 to better reflect the meaning of paragraph 2.4.2.2. of Annex 21, mainly to clarify the lateral limits of any opaque obscuration in this area.

Proposal for editorial corrections to align the definition on plastic glazing between the original English version and the French translation as well as of the communication annex on principal/secondary characteristics for laminated-glass windscreens.

Proposal to correct paragraph 16.1.3.1. as follows: “The minimum and the average magnification factors of the CMS, in both horizontal and vertical directions shall not be lower than the minimum average magnification factors indicated below.” The latter reference to “minimum average” should be deleted since the subsequent text provides the required minimum and average magnification factors.

The proposal also corrects the cross-reference in paragraph 6.3.3.2. where “the test shall satisfy the conditions laid down in paragraph 6.1.3. of this Regulation” should refer to paragraph 6.1.1.3. and aligns the communication form with with the scope of the Regulation regarding vehicle categories (adding category L).

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.

The proposal also introduces provisions for cargo-compartment refrigeration systems connected to the compressed natural gas (CNG) and/or liquefied natural gas (LNG) system(s).

Proposal from the WP.29 Secretariat for additional corrections to the table of tell-tales, concerning items 31 (Combustion
pre-heat; engine start aid) and 32 (Choke (cold starting device)).

Correction of a reference used in the original proposal for a new UN Regulation on agricultural vehicle couplings. In Annex 6, paragraph 1.7., 3.3.6. and 3.7.1.: The Term F_s is not needed and misleading. The vertical component of the test force is named F_v. This term should be used throughout the whole document concerning the vertical component of the test forces.

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).

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 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.
