Proposal to clarify the scope requirements for a UN Regulation, to specify that national authorities may apply additional requirements provided they are not covered by one or more applicable UN Regulations, and to delete the clause allowing Contracting Parties to refuse to accept type approvals granted under a preceding series of amendments after the entry into force of the latest series of amendments to a UN Regulation.

Proposal to allow for special type approval numbering schemes under individual UN Regulations as warranted, to allow up to six-digit sequential numbering in national approvals (from the current four), and to delete leading zeros in the numbering since Contracting Parties may use as leading digits, for example, the last two digits of a calendar year when a type approval was issued.

Document WP.29/343 is the “Status of the 1958 Agreement” which provides the current listing of UN Regulations, Contracting Parties applying each regulation, technical services authorized to conduct testing under each regulation, and so on. Revision 3 of the 1958 Agreement and UN R0 on International Whole Vehicle Type Approvals change the status document because Contracting Parties may accept earlier versions of UN Regulations and IWVTA approvals may be partial or universal based upon acceptance of specific regulations and/or versions. This submission from the WP.29 Secretariat provides guidance on how these changes will be reflected under the status document.
