Proposal to improve the text, adds that the definitions in UN R48 apply unless the regulation or the vehicle-category-specific regulations (UN R53, 78, 86) specify different applicable definitions, to clarify that the construction provision and prohibition on use of paints or varnishes under paragraph 4.1.6 only apply to retro-reflectors, to correct the omission of Class F devices from the title of paragraph 5.4., and to add the water-resistance test (from UN R69 and R70) to Annex 7.
This proposal (WP.29/2019/83) was adopted by the World Forum. Forty Contracting Parties out of the 55 applying UN R150 were present for the vote by AC.1. Forty voted in favor with zero against and zero abstaining.
