GB 15086-2013Motor vehicle door locks and retention components performance requirements and test methods (English PDF)

3.1 General requirements

3.1.1 Each articulated door system shall be fitted with at least one primary door latch system.

3.2 Performance requirements

3.2.1 Articulated door lock and door hinge

3.2.1.1 Load 1

When the latch and strike (or stop) assembly of each primary latch system is at secondary latched position, if applying 4500 N load perpendicular to the latch surface, it shall not be disengaged; when the latch and strike (or stop) assembly of each primary door latch system and auxiliary door latch system are at the fully latched position, if applying 11000 N load along the same direction, it shall not be disengaged.

3.2.1.3 Load 3 (only for rear door locks opened vertically)

As for the rear door lock opened vertically, at least one primary door latch system shall, in addition to complying with the requirements of 3.2.1.1 and

3.2.1.2, not be disengaged from the fully latched position if applying 9000 N load along the direction orthogonal to the direction of application of load 1 and load 2.

3.2.1.4 Inertial loads

Each primary door latch system and auxiliary door latch system shall comply with the dynamic requirements of a) and/or b) of the following inertial load requirements, OR comply with the calculation requirements of c).

Inertial load requirements.

3.2.1.5 Door hinges

3.2.1.5.1 Each door hinge system shall be capable of withstanding the performance requirements of the following door hinge systems.

a) Supports the door;

3.2.1.5.2 If the entire door hinge system is not tested and only a single hinge in a door hinge system is tested, the hinge shall be loaded in proportion to the total number of hinges in the door hinge system.

3.2.1.5.3 As for the side door with a rear-mounted hinge and which can be operated independently of other doors, it shall comply with all of the following rear-mounted hinge rear side door requirements.

3.2.2 Sliding door locks and retention components

3.2.2.1 Load 1

When at least one door latch system is at the fully latched position, if applying

11000 N load perpendicular to the latch surface of the latch and strike (or stop) assembly of the door latch system, it shall not be disengaged; when the latch and strike (or stop) assembly of the primary door latch system is at the secondary latched position, if applying 4500 N load along the same direction, it shall not be disengaged.

3.2.2.3 Inertial loads

The sliding door latch shall, in addition to complying with the requirements of

3.2.2.1 and 3.2.2.2, also comply with the dynamic requirements of a) or the calculation requirements of b) in the following inertial load requirements.

Inertial load requirements.

3.2.2.4 Sliding door retention components

3.2.2.4.1 As for the sliding door guide rail and sliding door assembly or other supporting method, when it is at the fully latched and closed position, respectively APPLY 9000N outwards transverse force onto the opposite sides of the door (18000 N in total), the sliding door guide rail and sliding door assembly or other supporting components shall not be disengaged from the door frame.

3.2.2.4.2 When performing the test of 3.2.2.4.1, if any one of the following conditions occurs, the sliding door retention component does not comply with the requirements.

3.2.3.2 A rear door fitted with an inside door handle or other inner lock opening control shall be provided with at least one latching device in the vehicle which, when locked, shall prevent the operation of the inner door handle and other inner lock opening controls, AND is able to open the door with independent action as well as operate the inner door handle and other inner lock opening control device.
