A door latch system with a fully latched position and a door closure warning system.
6.                                          Performance requirements
6.1.                                    Hinged doors
6.1.1.                              Load test one
6.1.1.1.                        Each primary door latch system and auxiliary door latch system, when in the fully latched position, shall not separate when a load of 11,000 N is applied in the direction perpendicular to the face of the latch such that the latch and the striker anchorage are not compressed against each other, when tested in accordance with paragraph 7.1.1.1.
6.1.1.2.                        When in the secondary latched position, the primary latch system shall not separate when a load of 4,500 N is applied in the same direction as in paragraph 6.1.1.1., when tested in accordance with paragraph 7.1.1.1.
6.1.2.                              Load test two
6.1.2.1.                        Each primary door latch system and auxiliary door latch system, when in the fully latched position, shall not separate when a load of 9,000 N is applied in the fork-bolt opening direction and parallel to the face of the latch, when tested in accordance with paragraph 7.1.1.1.
6.1.2.2.                        When in the secondary latched position, the primary latch system shall not separate when a load of 4,500 N is applied in the same direction, as in paragraph 6.1.2.1., when tested in accordance with paragraph 7.1.1.1.
6.1.3.                              Load test three ((applicable to doors that open in a vertical direction)
6.1.3.1.                        Each primary door latch system shall not disengage from the fully latched position when a vertical load of 9,000 N is applied.
6.1.4.                              Inertial load
 Each primary door latch system and auxiliary door latch system shall meet the dynamic requirements of either paragraphs 6.1.4.1. and 6.1.4.2. or the calculation of inertial load resistance requirements of paragraph 6.1.4.3.
6.1.4.1.                        Each primary door latch system and auxiliary door latch system on each hinged door shall not disengage from the fully latched position when an inertial load of 30 g is applied to the door latch system, including the latch and its activation device, in the directions parallel to the vehicle's longitudinal and transverse axes with the locking device disengaged and when demonstrated in accordance with paragraph 7.1.1.2.
6.1.4.2.                        Each primary door latch system and auxiliary door latch system on each hinged back door shall also not disengage from the fully latched position when an inertial load of 30 g is applied to the door latch system, including the latch and its activation device, in the direction parallel to the vehicle's vertical axis, with the locking device disengaged and when demonstrated in accordance with paragraph 7.1.1.2.
6.1.4.3.                        Each component or subassembly can be calculated for its minimum inertial load resistance in a particular direction. The combined resistance to the unlatching operation must assure that the door latch system, when
