47. The expert from Japan introduced the draft UN Regulation on Hydrogen and Fuel Cell Vehicles of category L (GRSP-61-03) with a presentation (GRSP-61-04). He explained that his country had established a national standard with similar provisions. However, he added that the mutual recognition of type approvals ensured by the 1958 Agreement to enable faster deployment such vehicles thus the reason for proposing a new UN Regulation instead of amending the UN GTR No. 13. GRSP requested experts to provide their comments on the proposal to the expert from Japan by the end of July. GRSP expected to resume discussion at its December 2017 session on the basis of a revised proposal and requested the secretariat to keep GRSP-61-03 as a reference on the agenda of the next session.
