8. The expert from China introduced GRB-55-05-Rev.1 proposing amendments (GRB-55-04) aimed at revising the definitions of the “pre-acceleration”, “reference point” and the “specific test conditions” for vehicles. The expert from ISO supported in principle the proposal, in line with the latest revision of ISO Standard 362, pending a study reservation on the specific test conditions. GRB agreed to resume discussion on this matter at its September 2012 session on the basis of a revised proposal prepared by the expert from China in collaboration with the expert from ISO. |
