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.

Presentation of issues raised during discussions of the GRE Task Force on EMC requirements with regard to the application of several UN Regulations to trolley buses depending upon their configuration (e.g., dual-mode operation either connected to overhead cables or in standard bus mode).

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.

Proposal to extend requirements introduced via Supplement 4 to the 04 series of amendments concerning barriers in the gangway and the amount of priority seats to the 05, the 06 and the 07 series of amendments.

Proposal to redefine the measurement criteria for determining appropriate seat spacing in order to address observed cases where adequate spacing is not achieved even though the current criteria are fulfilled. The type approval authorities of the member states of the European Union (TAAM) discussed the proper interpretation of the text of the Regulation in the case of seats with a central recess (sunken area) and decided that the text of the Regulation needed to be modified in order to provide an adequate method to measure the H dimension.

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.
