The 1958 agreement is an agreement reached within the framework of the EEC-UN to establish uniform standards for vehicles and their components with respect to safety, environment, energy and flight requirements. The title of the agreement reads: “Agreement on the adoption of uniform technical rules for wheeled vehicles, equipment and parts that can be mounted and/or used on wheeled vehicles and the conditions for mutual recognition of permits issued on the basis of these provisions.” The agreement aims to promote the harmonization of regulations and mutual recognition of authorisations between the contracting parties to the agreement. (For more details, see WP.29`s terms and conditions on page 32 of WP.29 “WP.29 How it Works – How It Can Join” here:www.unece.com.in org/trans/main/wp29wgs/wp29wgs/wp29gen/wp29pub.htmlThe agreement in its original form allowed only members of the EEC-EU to participate. The previous title was “Agreement on uniform registration conditions and mutual recognition of the registration of automotive equipment and parts, concluded in Geneva on 20 March 1958″It was revised in 1995 (revision 2) to encourage the participation of non-European countries and became a comprehensive agreement. In addition, the agreement recognizes self-certification as an alternative to receipt by type and therefore does not exclude countries whose rules and regulations are implemented by self-certification to become contracting parties. The amended text of the 1958 agreement (Revision 2) came into force on 16 October 1995. There are currently 41 parties to the agreement (Ireland, Cyprus and Malta due to accession to the EC). The regulations adopted under this agreement are known as UN regulations. 127 UN regulations are currently in force. A list of the titles of all regulations is available on pages 6 to 13 of the trans/WP.29/343 status document: (see: www.unece.org/trans/main/wp29/wp29wgs/wp29gen /wp29fdocstts.html)The text of the agreement as well that all its parts of the attached UN provisions can be accessed or downloaded here: www.unece.org/trans/main/wp29/wp29regs.html Instead of a United Nations-type reception system, vehicle safety rules in the United States and Canada apply on the principle of self-certification, The manufacturer or importer certifying a vehicle or part of the automotive equipment, d. h) confirms and promises that the vehicle or equipment meets all applicable federal or Canadian road safety standards , bumper and theft protection.  A public or licensed screening body does not require due diligence before the vehicle or equipment can be imported, sold or used.
If the certification is false or incorrect, i.e. the vehicle or equipment is not compliant, the authorities may conduct checks and, if a non-compliance is found, order a recall and/or other corrective and/or punitive measures. Vehicle and equipment manufacturers can appeal such sanctions, but this is a difficult direction.  Violations found, which are not likely to affect road safety, may be asked to skip recall requirements (corrective measures and notifications) for vehicles already manufactured.  WP.29 was established on 6 June 1952 as a working group on vehicle construction, a subsidiary body of the Internal Transport Committee (ITC) of the United Nations Economic Commission for Europe (EEC-UN).
