Proposal to further refine the transitional provisions of UN R48. In 2014, the transitional provisions of UN R48 were changed in order to avoid having more than one series of amendments in force at the same time (via Supplement 3 to the 06 series of amendments). This change allows earlier series of amendments to be “frozen” and used under the International Whole Vehicle Type Approval system (IWVTA) as “versions” of UN R48. However, the possibility for the partial application of a series of amendments resulting from the installation of new equipment on a vehicle approved to an earlier series has been raised within the IWVTA. This proposal refines the transitional provisions in order to enable partial application of a series through an extension of the existing approval rather by requiring a new approval. At the same time, the proposal aims to ensure that the safety objectives of UN R48 are met.
20. The expert from GTB proposed modifications to the transitional provisions of various series of amendments to allow for optional installation of new equipment on a vehicle, which had already been approved to an earlier series of amendments, by extending the existing approval, rather than requesting a new approval based on the latest series of amendments (ECE/TRANS/WP.29/GRE/2016/10). The expert from OICA advocated the proposal and pointed out that it would contribute to increasing traffic safety (GRE-75-12). The experts from Finland, Italy and Netherlands also supported the proposal. The experts from Austria, France and UK expressed concerns about too many series of amendments to Regulation No. 48 in force and were not convinced that the earlier series should be amended. GRE decided to continue this discussion at the next session.
