The core of the Forum's work is based around the "1958 Agreement", formally titled "Agreement concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted and/or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions" (E/ECE/TRANS/505/Rev.2, amended on 16 October 1995). This forms a legal framework wherein participating countries (contracting parties) agree on a common set of technical prescriptions and protocols for
type approval of vehicles and components. These were formerly called "UNECE Regulations" or, less formally, "ECE Regulations" in reference to the Economic Commission for Europe. However, since many non-European countries are now contracting parties to the 1958 Agreement, the regulations are officially entitled "UN Regulations". According to the mutual recognition principle set in the Agreement, each Contracting Party's Type Approvals are recognised by all other Contracting Parties.
Participating countries Formally signing the 1958 Agreement was possible till June 30 of that year, and five countries chose to do so: Italy (March 28), Netherlands (March 30), West Germany (June 19), France (June 26), and Hungary (June 30). Sweden and Belgium acceded soon after. Originally, the agreement allowed participation of
ECE member countries only, but in 1995 the agreement was revised to allow non-ECE members to participate. Current participants include the European Union and its member countries, as well as non-EU UNECE members such as Norway, Russia, Ukraine, Serbia, Belarus, Kazakhstan, Turkey and Azerbaijan, and even remote territories such as South Africa, Australia, New Zealand, Japan, South Korea, Thailand and Malaysia. Contracting parties to the 1958 Agreement are referenced by a
Distinguishing Number, historically corresponding to the chronological order in which the country joined it or the UNECE AERT Agreement (1970). , the participants of the Agreement, with their Distinguishing Number, were: †
"In order to ensure in the future conformity between conventional signs in the 1958 Agreement and those set up in the [1970] AETR Agreement new Contracting Parties should be allocated the same number in both Agreements." ‡
"European Union...Approvals are granted by its Member States using their respective ECE symbol" Most countries, even if not formally participating in the 1958 agreement, recognise the UN Regulations and either mirror the UN Regulations' content in their own national requirements, or permit the import, registration, and use of UN type-approved vehicles, or both. The
United States and
Canada (apart from Lighting Regulations) are the two significant exceptions; the UN Regulations are generally not recognised and UN-compliant vehicles and equipment are not authorised for import, sale, or use in the two regions, unless they are tested to be compliant with the region's car safety laws, or for limited non driving use (e.g. car show displays).
Type approval, e-Mark, E-Mark , Bottom - according to
EU regulations or
directives. The 1958 Agreement operates on the principles of
type approval and
reciprocal recognition. Any country that accedes to the 1958 Agreement has authority to test and approve any manufacturer's design of a regulated product, regardless of the country in which that component was produced. Each individual design from each individual manufacturer is counted as one individual type. Once any acceding country grants a type approval, every other acceding country is obliged to honor that type approval and regard that vehicle or item of motor vehicle equipment as legal for import, sale and use. Items type-approved according to a UN Regulation are marked with an
E and the country's
Distinguishing Number, within a circle. A capital
(E) in a circle indicates compliance with a
UN regulation, while a lower case
[e] in a box indicates compliance with a
EU directive (e.g. issued by EC, EU). This number indicates which country approved the item, and other surrounding letters and digits indicate the precise version of the regulation met and the type approval number, respectively. Although all countries' type approvals are legally equivalent, there are real and perceived differences in the rigour with which the regulations and protocols are applied by different national type approval authorities. Some countries have their own national standards for granting type approvals, which may be more stringent than called for by the UN regulations themselves. Within the auto parts industry, a German (E1) type approval, for example, is regarded as a measure of insurance against suspicion of poor quality or an undeserved type approval.
UN Regulations , there are over 170 UN Regulations appended to the 1958 Agreement; most regulations cover a single vehicle component or technology. A list of current regulations applying to passenger cars follows, with regulations specific to heavy vehicles, motorcycles, tractors, etc. grouped separately. The
European Union also applies other UNECE regulations for cars produced in unlimited series, and also applies its own (non-UNECE) regulations such as
European Community regulations. Regulation 0 "International Whole Vehicle Type Approval (IWVTA)" was recently introduced to define international compliance to a set of regulations.
