Regulation No. 11

UNIFORM PROVISIONS CONCERNING THE APPROVAL OF VEHICLES

WITH REGARD TO DOOR LATCHES AND

DOOR RETENTION COMPONENTS

1.	SCOPE

This Regulation applies to latches and door retention components such as hinges and other supporting means on side doors of vehicles of categories of M 1 and N 1 1/ used for, or which can be used for, the entry or exit of the occupants.

2.	DEFINITIONS

For the purposes of this Regulation.

2.1	"Approval of a vehicle" means the approval of a vehicle type with regard to door latches and door retention components.

2.2.	"Vehicle type" means a category of motor vehicles which do not differ in such essential respects as:

2.2.1.	designation of the vehicle type by the manufacturer;

2.2.2.	the type of latch;

2.2.3.	the type of door retention component;

2.2.4.	the way in which the latches and door retention components are fitted to and retained by the structure of the vehicle;

2.2.5.	type of sliding doors;

2.3.	"Doors" means hinged or sliding doors which lead directly into a compartment that contains one or more seating positions and which are not folding doors, roll-up doors and doors that are designed to be easily attached to or removed from motor vehicles manufactured for operation without doors.

3.	APPLICATION FOR APPROVAL

3.1.	The application for approval of a vehicle type with regard to door latches and door retention components shall be submitted by the vehicle manufacturer or by his duly accredited representative.

----------

1/	As defined in Regulation No. 13

3.2	It shall be accompanied by the undermentioned documents in triplicate and the following particulars:

3.2.1.	drawings of the doors and of their latches and door retention components on an appropriate scale and in sufficient detail;

3.2.2.	a technical description of the latches and door retention components.

3.3.	The application shall also be accompanied by:

3.3.1.	A batch of five sets of retention components per door. When, however, the same sets are used for several doors, it will be sufficient to submit one batch of sets. Sets of door retention components which are distinguishable only because they are designed to be fitted on the left or on the right are not regarded as different;

3.3.2.	A batch of five complete latches, including actuating mechanism, per door. When, however, the same complete latches are used for several doors, it will be sufficient to submit one batch of latches. Latches which are distinguishable only because they are designed to be fitted on the left or on the right are not regarded as different.

3.4.	A vehicle, representative of the vehicle type to be approved, shall be submitted to the technical service responsible for conducting approval tests.

4.	APPROVAL

4.1.	If the vehicle type submitted for approval pursuant to this Regulation meets the requirements of paragraphs 5. and.6 below, approval of that vehicle type shall be granted.

4.2.	An approval number shall be assigned to each type approved. Its first two digits (02) 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 may not assign the same number to the same vehicle type either if the doors are not equipped with latches or door retention components of the same type, or if the latches and door retention components are not fitted in the same manner as on the vehicle submitted for approval; on the other hand, it may assign the same number to another vehicle type whose doors are equipped with the same latches and door retention components fitted in the same

manner as on the vehicle submitted for approval.

4.3.	Notice of approval or of refusal of approval of a vehicle type pursuant to this Regulation shall be communicated to the Parties to the Agreement which apply this Regulation, by means of a form conforming to the model in annex 1 to this Regulation and of drawings of the doors and of their latches and door retention components supplied by the applicant for approval, in a format not exceeding A4 (210 x 297 mm) or folded to this format and on an appropriate scale.
4.4.	There shall be affixed, conspicuously and in a readily accessible place specified on the approval form, to every vehicle conforming to a vehicle type approved under this Regulation, an international approval mark consisting of:

4.4.1.	a circle surrounding the letter "E" followed by the distinguishing number of the country which has granted approval; 1/

4.4.2.	the number of this Regulation, followed by the letter "R", a dash and the approval number to the right of the circle described in paragraph 4.4.1.

4.5.	If the vehicle conforms to a vehicle type approved, under one or more other Regulations annexed to the Agreement, in the country which has granted approval under this Regulation, the symbol prescribed in paragraph 4.4.1. need not be repeated; in such a case the Regulation and approval numbers and the additional symbols of all the Regulations under which approval has been granted in the country which has granted approval under this Regulation shall be placed in vertical columns to the right of the symbol prescribed in paragraph 4.4.1.

4.6.	The approval mark shall be clearly legible and be indelible.
