The full addresses of the administrative department and technical services corresponding to the address codes mentioned above are listed in Schedule 1 of the TRANS/WP status document.29/343. The multilingual status document can be found on the WP.29 website (please note that this document is extensive and contains approximately 300 pages): www.unece.org/trans/main/wp29/wp29wgs/wp29gen/wp29fdocstts.html In accordance with Article 12 of the agreement, an amendment to a regulation is deemed to have been adopted, except within six months of notification by the Secretary-General, more than one third of the contracting parties applying the regulation on the date of notification have informed the Secretary-General of his refusal.
