UNECE secretariat response to the question on preparation (upon the request of a CP) of “former versions of UN Regulation”

OICA input concerning the proposed concept for “versions” of UN Regulations for use within the global system for the mutual recognition of type approvals. A version involves the possibility for issuance of new approvals to previous forms of a given regulation (as opposed to the current system where parties can only issue new approvals to the latest version in force of a regulation).

The International Whole Vehicle Type Approval system under development proposes to allow for the acceptance by Contracting Parties of approvals issued according to versions of a regulation earlier than the latest version in force as well as of approvals issued under some, but not all, regulations that comprise the IWVTA. This document proposes an approach to manage the various configurations of the Limited IWVTA.
