Proposal to align UN R43 with GTR 6 and UN R125 with regard to the aiming positions of the driver’s eyes. This proposal corrects inconsistencies introduced during the transposition of GTR 6 into UN R43.

Proposal to improve the specifications for LPG multi-valves in response to an LPG vehicle fire that resulted in injuries to first responders. A German Type Approval Authority (KBA) analysis concluded that the hose connecting the PRV/PRD of the multi-valve to the gaseous phase was damaged and hose-fragments blocked both PRV and PRD such that pressure could not be adequately reduced. The PRV and PRD were activated, but the fragments considerably reduced the effective section of the relevant tubing and prevented the release of pressure. This proposal aims to prevent such occurrences.

Proposal for a new series of amendments to UN Regulation No. 110 to improve the specifications for the installation and inspection of CNG cylinders and of LNG tanks and their accessories. This proposal addresses incidents caused by cylinder corrosion. The proposal aims to reinforce the requirements for adequate cylinder protection and for sufficient access to the cylinder and its accessories to allow regular visual inspection.

Proposal to clarify that footnote ¹⁸ of Table 1 applies to telltale no. 1 (Master lighting switch) when it is combined with telltale no. 19 (Position, side marker, and/or end-outline marker lamps). Footnote ¹⁸ states, “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.”

Proposal to exempt all heaters located outside the passenger compartment and using water as a transfer medium from the requirements of the annexes on air quality and temperature. The current text only exempts combustion heaters.

Proposal to replace the prohibition against the use of reinforced insulation for trolleybus circuits directly connected to the overhead power line with a requirement that such circuits shall be double insulated.

Proposal to change the units for vehicle masses from tonnes to kilograms in R.E.3.

Supplement 1 to the 02 series of amendments modified the definition of “interior compartment” (previously “passenger compartment”) in paragraph 2.2. The definition replaced the term “roof” by “ceiling” in reference to the upper boundary surface of the compartment definition. Nonetheless, use of the term “roof” was not updated throughout the regulation. This proposal corrects the omission by substituting “ceiling” for “roof” throughout the text.
