Within the EU, there is total harmonisation of registration rules and mutual recognition. Outside the EU, not all signatory countries apply all the rules. Many countries, such as Russia, have incorporated these rules into their national registration law. The same is true in Japan. However, even if few EEC-UN regulations are implemented, this is already a first step towards harmonization. Tires: The Rubber Manufacturers Association and five other tire manufacturers around the world have asked NHTSA to change the US standard (FMVSS No. 109) to adopt a standard, the Global Tire Standard 2000, which has been approved by the tire industry worldwide. The same proposal was submitted to WP.29 for consideration as a comprehensive regulation. The Agency considers tyre harmonization a priority, as FMVSS 109, designed primarily for biased tyres, needs to be updated and upgraded for radial tyres. The Agency is also of the view that some testing requirements in other national standards are more appropriate for radial tyres and that their adoption would be an improvement over the provisions of the U.S. standard for biased tyres. The aim is to harmonize tyre performance requirements by introducing best practices into national tyre standards around the world and to improve these practices when support data is available.
NHTSA will consider all public comments and publish a revised list of recommendations. The Agency will present its list to WP.29 in November and use it to discuss with other contracting parties the definition of priorities under the 1998 comprehensive agreement. The Global Forum for the Harmonization of Vehicle Regulations is a working group (WP.29) of the Sustainable Transport Division of the United Nations Economic Commission for Europe (UN-EEC). Its mission is to manage the multilateral agreements signed in 1958, 1997 and 1998 on technical requirements relating to the construction, registration of bicycle vehicles and their regular technical inspection and to work within the framework of these three agreements to develop and amend UN regulations, UN global technical regulations and UN regulations. , a kind of vehicle regulation.
