Proposal to expand the scope of the regulation by deleting paragraph 1.2.2. which allows for the exclusion of “vehicles designed and constructed for special purposes where it is not possible, for practical reasons, to fit lateral protection devices” from the text. The UK submits that paragraphs 13 and 16 of the regulation provide specific provisions that address this situation whereas the exclusion clause allows for a broader interpretation that unnecessarily limits the use of lateral protection devices. Moreover, exemptions may still be accorded at the national level.

Proposal to clarify the scope and the application of the regulation. The proposal clarifies that the regulation applies to “the burning behaviour of electric cables and cable sleeves or cable conduits used in the vehicle” and it updates the reference to paragraph 5.22. of ISO 6722-1:2011. Specifically, the proposal would apply testing to electric cables, cable sleeves, and cable conduits that exceed a length of 100 mm.

At the May 2015 Type Approval Authorities Meeting (TAAM), Poland raised concerns (attached with this submission) over small M₁ vehicles being equipped with aftermarket coupling devices where the vehicle in question is not designed for towing a trailer. In effect, these vehicles are not permitted to tow trailers, but are nonetheless enabled to be equipped for such a purpose by the aftermarket devices. Therefore, Poland proposes to amend UN R55 to ensure that coupling devices are only approved for use on vehicles approved for towing trailers.

Proposal to transfer electrical safety provisions for trolleybuses (Annex 12) from UN R107 to UN R100. In 2006, the provisions of UN R36, UN R52, and UN R107 were merged through the 02 series of amendments to UN R107. In 2015, Annex 12 of UN R107 was amended to align additional safety prescriptions for electrical safety of trolleybuses with the corresponding electrical standards. However, UN R100 has evolved beyond its initial focus on battery electric vehicles and currently presents a more appropriate location for maintaining the trolleybus electrical safety provision of Annex 12. For the provisions of Annex 1 – Part 1 – Appendices 1, 2 and 3, where a list of characteristics of a trolleybus was added apart from the special environmental conditions, a reference will be inserted to Annex 6 – Part 1 and Annex 7 of UN Regulation No. 100. A corresponding proposal for amendments will be submitted as an official document to the Working Party on Passive Safety.

Proposal to harmonize UN R110 with standard ISO 11439:2013 on high pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles.

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 define an exemption for handles from “residual/survival space” intrusion requirements for vehicle spaces not intended for occupants. Handles and handholds used to assist passengers in entering and exiting a bus are located outside of passenger seating and standing areas where OICA argues that they do not present a danger; however, the current rollover testing provisions could result in their inclusion in the area defined as “residual/survival space” where any intrusion is prohibited.

Proposal to harmonize the Russian text with the English-language version of the regulation.

Proposal prepared by the UNECE secretariat to align the provisions of UN Regulation No. 105 with those of the new 2017 edition of the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR).

Proposal to delete the volume and shape limits of the fume cupboard described in Annex 8 (Test to determine the vertical burning rate of materials) and replace these with the performance specification that the fume cupboard dimensions shall not affect the test results. The proposal also sets a minimum sample size of 375 × 170 mm under paragraph 3.1. of Annex 8.

Revised approach to resolving the issues raised in Romania’s proposal GRSG/2015/21 to redefine the measurement criteria for determining appropriate seat spacing. This proposal has been developed collaboratively by Romania, OICA, and CCLCR with respect to discussions held by the type approval authorities of the member states of the European Union (TAAM). The proposal includes the use of a new testing gauge for the H dimension measurement.

Communication to GRSG of work within GRE concerning electromagnetic compatibility provisions for trolley buses (UN R10 and UN R107) and on approval of amendments to UN R7, 87, and 48 concerning lighting failure indicators that may impact UN R121 on telltales and indicators.

Proposal to align the CNG cylinder requirements in Regulation No. 110 with requirements in ISO 11439: 2013.

Proposal to enable the use of alternate colors (per footnote 18 of Table 1 and in line with ISO Standard 2575) for certain lighting tell-tales in order to indicate light source failures in response to the proposals for light failure indicators under UN Regulations Nos. 7, 48 and 87 (GRE/2016/7, GRE/2016/12 and GRE/2016/17) as adopted by GRE. This proposal anticipates use of the same approach in response to plans for additional failure indication requirements for other lighting regulations.

Proposed corrections to the original proposal to align UN R105 with ADR 2017.

Proposal to clarify paragraph 7.7.5.1. with regard to ceiling-mounted displays or monitors and simplify the testing procedure:

• The gauge shall be used only for the identification of the monitors to be tested.
• The simplified way to apply the removal force corresponds to a passenger pushing the monitor/display with its hand, and in these conditions the acceptable force limit is adapted.
• The test must be conducted in both directions.
• The proposed wording for the last condition to fulfil is more technology neutral, the case of automatic redeployment is also considered and banned.

Presentation of data to supplement discussions on improvements to the driver field of view, especially with respect to indirect vision (rear, blind spot, mirrors, camera systems).

Proposal for improvements to the driver rear field-of-view requirements towards reducing pedestrian accidents.

Proposal to introduce new requirements and test procedures for rear-view systems in order to reduce risks of pedestrian collisions while vehicles move in reverse.
