Document GRE/2014/13 proposes to ensure that the introduction of the new class F marking materials does not conflict with the mandatory requirements for existing class C materials. The addition of Class F brings markings required under certain countries’ national legislation within the UN regulatory system. However, Japan actually prohibits the use of white retro-reflective markings on the rear of vehicles. Therefore, Japan proposes the addition of a footnote confirming the right of Contracting Parties to prohibit the use of Class F markings under national legislation.
63. The expert from Japan introduced GRE-71-27 and GRE-71-28, proposing to insert a new footnote to read “The Contracting Parties applying this UN Regulation may prohibit the use of Retro-Reflecting materials approved as Class F on the basis of national regulations.” GRE concluded that it is obvious even without such a footnote that the Contracting Parties may prohibit the use of such materials. As a result of discussion, these informal documents were withdrawn.
