Proposed changes to the working draft text ACSF-04-20.

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 transfer provisions for electrical safety of trolleybuses from UN Regulation No. 107 (M2 and M3 vehicles) to UN Regulation No. 100 (Electric Power Trained Vehicles). This proposal seeks to clarify the scope of the two Regulations with regard to the electrical safety of trolleybuses.

The proposal by Belgium GRSG/2016/05 aimed at removing the amended additional safety prescriptions for trolleybuses from annex 12 of UN Regulation No. 107 for the Construction of M2 and M3 vehicles (R107), and inserting them into UN Regulation No. 100 on Electric Powertrain Vehicles (R100), see proposal GRSP/2016/07. This document explains how the scope and technical provisions for trolleybuses of R100 and R107 are complementary, but not yet fully compatible.
