The following shall be submitted to the technical service responsible for the approval tests: Two seats representative of the type to be approved, in the case of approval of a seat, 2.

If the vehicle submitted for approval under this Regulation meets the relevant requirements of paragraph 6 below, approval of that vehicle type shall be granted. An approval number shall be assigned to each type approved. Its first two digits at present 00 for the Regulation in its original form shall indicate the series of amendments incorporating the most recent major technical amendments made to the Regulation at the time of issue of the approval.

The same Contracting Party shall not assign the same number to any other seat type or any other vehicle type. Subsequent numbers shall be assigned to other countries in the chronological order in which they ratify or accede to the Agreement concerning the Adoption of Uniform Conditions of Approval and Reciprocal Recognition of Approval for Motor Vehicle Equipment and Parts, and the numbers thus assigned shall be communicated by the Secretary-General of the United Nations to the Contracting Parties to the Agreement.

The number of this Regulation, followed by the letter R, a dash and the approval number, placed to the right of the circle prescribed in paragraph 4. The approval mark shall be clearly legible and shall be indelible.

As the case may be, the approval mark shall be placed on the seat or seats or on, or close to, the data plate affixed to the vehicle by the manufacturer. Examples of arrangements of approval marks are given in annex 3.

Another suitable test may be used provided that its equivalence with one of the prescribed tests is demonstrated. The test is to determine: 5. If the seat occupant s is are correctly retained by the seat s in front of him them.

This requirement shall be considered satisfied: 5. If the seat occupant s is are not seriously injured. The seat and the seat mountings are strong enough. No part of the seat, the seat mountings or the accessories becomes completely detached during the test; The seat remains firmly held, even if one or more anchorages is partly detached, and all the locking systems remain locked during the whole duration of the test; After the test no structural part of the seat or accessories has any fracture or sharp or pointed edges or corners likely to cause any bodily injury.

All fittings forming part of the back of the seat or accessories thereto shall be such as to be unlikely to cause any bodily injury to a passenger during impact. This requirement shall be considered satisfied if any part contactable by a sphere mm in diameter presents a radius of curvature of at least 5 mm. If any part of the fittings and accessories referred to above is made of a material of hardness less than 50 shore A on a rigid backing, the requirements set out in paragraph 5.

The parts of the back of the seat such as adjustment devices for the seat and accessories shall not be subject to any requirements of paragraph 5. The adjustment and locking systems shall not be required to be in full working order after the test. The seat need not be an approved seat provided that it satisfies the requirements of paragraph 5.

Permanent deformation, including breakage, of an anchorage or the surrounding area shall be permissible provided the prescribed force has been sustained throughout the prescribed period. When there is more than one type of anchorage on a vehicle, each variant shall be tested in order to obtain approval for the vehicle. One test may be used to approve simultaneously a seat and a vehicle.

In order to verify that the requirements of paragraph 7. In this case, suitable controls means checking the dimensions of the product as well as the existence of procedures for the effective control of the quality of products. The holder of the approval shall in particular: have access to control equipment necessary for checking the conformity to each approved type; ensure that data of test results are recorded and that annexed documents shall remain available for a period to be determined in accordance with the administrative service; analyse the results of each type of test, in order to verify and ensure the stability of the product characteristics, making allowance for variation of an industrial production.

The competent authority which has granted type approval may at any time verify the conformity control methods applicable to each production unit and carry out on samples any test deemed necessary among the tests carried out for the approval. The normal frequency of inspections authorized by the competent authority shall be one per year. In the case where negative results are recorded during one of these visits, the competent authority shall ensure that all necessary steps are taken to re-establish the conformity of production as rapidly as possible.

Confirmation or refusal of approval, specifying the alterations shall be communicated by the procedure specified in paragraph 4. Upon receiving the relevant communication that authority shall inform thereof the other Parties to the Agreement applying this Regulation by means of a communication form conforming to the model in annex 1 and or annex 2 to this Regulation.
