111. The expert from UK presented a proposal for amendments to UN Regulation No. 13 (GRVA-16-45), resulting from the review of a query raised by the Working Party on the Transport of Dangerous Goods (WP.15) on amendments to UN Regulation No. 13 (Supplement 18 to the amendments of the 11 series), which introduced special requirements on endurance brakes for vehicles using regenerative braking systems. He stated that the proposed amendment aimed at clarifying the current understanding of provisions related to the Type IIA test. 112. The expert from the Netherlands welcomed the proposal and stated that he would come back to it after further internal exchange. 113. The expert from the Czech Republic, also attending the sessions of WP.15, stated that the new wording was in line with WP.15’s understanding of this Supplement 18 to the 11 series of amendments to UN Regulation No. 13. He stated that more clarifications were also needed for Annex 5 on ADR, as the provisions explicitly referred to paragraph 1.8 of Annex 4, but did not address the alternatives for electric vehicles that were introduced in the Regulation (see paragraph 5.1.2. of the regulation itself). 114. The experts from Norway and OICA supported the proposal in principle. 115. GRVA requested the secretariat to distribute informal document GRVA-16-45 with an official symbol at the next session. |
