COMMISSION DIRECTIVE 92/62/EEC of 2 July 1992 adapting to technical progress Council Directive 70/311/EEC relating to steering equipment for motor vehicles and their trailers

THE COMMISSION OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Economic Community,

Having regard to Council Directive 70/311/EEC of 8 June 1970, on the approximation of the laws of the Member States relating to steering equipment of motor vehicles and their trailers (1) and in particular Article 3 thereof,

Whereas a comprehensive evaluation of Directive 70/311/EEC has shown that it is possible to improve road safety further by applying practical experience and technological development and taking into account the progress made in the Economic Commission for Europe of the United Nations, notably in Regulation No 79 and supplements 1 and 2 thereto. These improvements may be obtained by reducing steering control effort, inserting requirements for power-assisted steering equipment using the same energy source as the braking device, introducing a steering test at higher speed for motor vehicles, introducing requirements for auxiliary steering equipment, and introducing a uniform presentation for the information document and the EEC type-approval certificate in order to facilitate computerization of storage and transmission of data by applicants and approval authorities;

Whereas it is also necessary to adapt to technical progress definitions and existing requirements;

Whereas the provisions of this Directive are in accordance with the opinion of the Committee on the Adaptation to Technical Progress of the directives on the removal of technical barriers to trade in motor vehicles, set up under Article 12 (1) of Directive 70/156 (2),

HAS ADOPTED THIS REGULATION:

Article 1

1. Directive 70/311/EEC is modified as follows:

in Article 2 the word 'Annex' is replaced by the word 'Annexes'.

2. The Annex is replaced by the Annexes to this Directive.

Article 2

1. With effect from 1 January 1993 no Member State may on grounds relating to steering equipment:

- refuse, in respect of a type of vehicle, to grant EEC type-approval, or to issue the copy of the certificate provided for in the last indent of Article 10 (1) of Council Directive 70/156/EEC, or to grant national type-approval, or

- prohibit the entry into service of vehicles,

if the steering equipment of this type of vehicle or of these vehicles comply with the provisions of Directive 70/311/EEC, as amended by this Directive.

2. With effect from 1 October 1993 Member States:

- shall no longer issue the copy of the certificate provided for in the last indent of Article 10 (1) of Directive 70/156 in respect of a type of vehicle,

of which the steering equipment does not comply with the provisions of Directive 70/311/EEC, as amended by this Directive.

3. With effect from 1 October 1995 Member States may prohibit the entry into service of vehicles of which the steering equipment does not comply with the provisions of Directive 70/311/EEC, as amended by this Directive.

Article 3

1. Member States shall implement the provisions necessary to comply with this Directive before 1 January 1993. They shall forthwith inform the Commission thereof.

When Member States adopt these provisions, these shall contain a reference to this Directive or shall be accompanied by such reference at the time of their official publication. The procedure for such reference shall be adopted by Member States.

2. Member States shall ensure that they communicate to the Commission the wording of any essential provisions of national law that they adopt in the field covered by this Directive.

Article 4

This Directive is addressed to the Member States. Done at Brussels, 2 July 1992. For the Commission

or 1.6.4.1.3. pneumatic or mechanical/pneumatic means. In either case, where the mechanical part of the transmission is designed only to give position feedback and is too weak to transmit the total sum of the steering forces, this system shall be considered to be purely hydraulic, respectively purely electric, or purely pneumatic steering transmission; 1.6.4.2. Other hybrid steering transmission means any other combination of the abovementioned steering transmissions. 2. APPLICATION FOR EEC TYPE-APPROVAL 2.1. The application for approval of a vehicle type with regard to the steering equipment shall be submitted by the vehicle manufacturer. 2.2. It shall be accompanied by the information required by the information document which is attached as Annex II. 2.3. A vehicle representative of the vehicle type to be approved shall be submitted to the technical service responsible for conducting approval tests. 3. EEC TYPE-APPROVAL A certificate conforming to the model specified in Annex VI shall be issued by the authority granting an EEC type-approval pursuant to this Directive. 4. CONSTRUCTION PROVISIONS 4.1. General provisions 4.1.1. The steering equipment shall ensure easy and safe handling of the vehicle up to its maximum design speed or, in the case of a trailer, up to its technically permitted maximum speed. There must be a tendency to self-centre when tested in accordance with item 5. The vehicle shall meet the requirements of item 5.2 in the case of motor vehicles and of item 5.3 in the case of trailers. If a vehicle is fitted with ASE, it shall also meet the requirements of Annex IV. Trailers equipped with purely hydraulic steering transmissions shall also comply with Annex V. 4.1.1.1.
