There is no harmonized regulatory framework at the global level. In Europe, the regulatory framework is defined by EU directives, regulations and standards. However, in other countries, it is customary to find other frameworks, such as the self-certification system or a specific legal framework. In some cases, the regulatory requirements of the EEC-UN are used as a basis in their specific legal framework. The next chapter presents the methodology used in some of the countries concerned. Under Article 12 of the agreement, an amendment to a regulation is deemed to have been adopted, unless, 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. Given the administrative time required to develop the document and the notification procedure, an amendment will take effect approximately nine months after its adoption by WP.29 and AC.1. A contracting party to the 1998 agreement may accept any UN GTR that interests it. A party that votes in favour of the creation of a United Nations GTR is required to submit the technical regulation by its government to the procedure for adopting such a technical regulation in its own legislation. However, it is free not to adopt this UN decision and to justify the decision under this procedure. For more information, see Article 7 of the 1998 Agreement: www.unece.org/trans/main/wp29/wp29wgs/wp29gen/wp29glob.htmlA contracting party may also decide to accept products corresponding to a UN CSR, without including as much in their own laws or regulations.
(i.e., the UN-GTR can take the form of a national regulatory option). From 2015[update], 135 UN regulations were attached to the 1958 agreement; most prescriptions relate to a single component of the vehicle or a single vehicle technology. This results in a sub-list of rules for passenger cars (heavy vehicles, motorcycles, etc.) may be subject to derogatory provisions. The first signatories to the 1958 agreement included Italy (28 March), the Netherlands (30 March), Germany (19), France (26), Hungary (30 June), Sweden and Belgium. Initially, the agreement only allowed the participation of the ECEC member countries, but in 1995 the agreement was revised to allow the participation of non-MEMBERS of the ERC. Current participants include the European Union and its member countries, as well as non-EEC-UN countries such as Norway, Russia, Ukraine, Croatia, Serbia, Belarus, Kazakhstan, Turkey, Azerbaijan and Tunisia, and even remote regions such as South Africa, Australia, New Zealand, Japan, South Korea, Thailand and Malaysia. Under the 1958 agreement, a regulation does not provide for different levels of rigour. However, when a regulation is amended and at least one-fifth of the contracting parties applying the unchanged regulation state that they wish to continue to apply the unmodified regulation, the unchanged regulation is considered an alternative to the amended regulation.
Thus, it will be formally in the Regulation.In such a case, the contracting parties will be able to choose which alternative they wish to accept. The party opting for an earlier version must accept the authorizations granted under the latest amendments. However, the party opting for the most recent amendment is not required to accept the authorizations granted for earlier versions of the regulation. Most countries, even if they do not formally participate in the 1958 agreement, recognize the provisions of the United Nations and reflect the content of UN regulations in their own national requirements, or authorize the importation, registration and use of UN vehicles or both.
