ANNEX 3

LATCH TEST FOR LOAD TESTS ONE, TWO, AND THREE, FORCE APPLICATION

1. PURPOSE

These tests are intended to establish minimum performance requirements and test procedures for evaluating and testing vehicle door latch systems for their ability to resist force loads in directions perpendicular to the latch face and parallel to the latch face in the fork-bolt opening direction. For doors which open in a vertical direction, the tests are intended to also establish minimum performance requirements and a test procedure for evaluating the primary latch system in a direction orthogonal to the first two directions. Primary door latch systems must demonstrate the ability to resist applicable force loads in both the fully and secondary latched positions; auxiliary door latch systems, and other door latch systems with only a fully-latched position, must demonstrate the ability to resist force loads in directions perpendicular to the latch face and parallel to the latch face in the fork-bolt opening direction at the levels specified for the fully latched position.

ANNEX 4

INERTIAL TEST PROCEDURES

1. PURPOSE

To determine the ability of the vehicle latch system to resist inertial loading by means of a mathematical analysis of the component parts in their true car relationship or by evaluation using a dynamic test.

2. TEST PROCEDURES

2.1. Option 1, Calculation.

2.1.1. The procedure described in this Annex provides a means for analytically determining the ability of a door latch system to withstand inertial loading. Spring forces are the average of the minimum spring output in the installed position and the minimum spring output in the release position. Friction effects and work to be done are not considered in the calculations. Gravitational pull on components may also be omitted if it tends to restrict unlatching. These omissions from the calculations are permissible because they provide additional factors of safety.

2.1.2. Calculation consideration — each component or subassembly can be calculated for its minimum inertial load resistance in a particular direction. Their combined resistance to the unlatching operation must assure that the door latch system (when properly assembled in the vehicle door) will remain latched when subjected to an inertial load of 30 g in any direction. Figure 4-1 is an example of the components and combinations of components to be considered.

2.2. Option 2, Full Vehicle Dynamic Test

2.2.1. Test equipment

2.2.1.1. An acceleration (or deceleration) device.

2.2.1.2. One of the following vehicles:

2.2.1.2.1.

A full vehicle including at least door(s), door latch(es), exterior door handle(s) with mechanical latch operation, interior door opening lever(s), the locking device(s), interior trim and door seal.

2.2.1.2.2.

A vehicle body in white (i.e. vehicle frame, doors and other door retention components) including at least door(s), door latch(es), exterior door handle(s) with mechanical latch operation, interior door opening lever(s), and the locking device(s).

2.2.1.3. A device or means for recording door opening.

2.2.1.4. Equipment for measuring and recording accelerations.

2.2.2. Test setup

HINGE TEST PROCEDURE

1. PURPOSE

These tests are conducted to determine the ability of the vehicle hinge system to withstand test loads:

(a) in the longitudinal and transversal directions and, in addition;

(b) for doors that open in a vertical direction, vertical vehicle direction.

2. TEST PROCEDURE

2.1. Multiple Hinge System

2.1.1. Longitudinal load test

2.1.1.1. Equipment

2.1.1.1.2. A typical static test fixture is illustrated in Figure 5-1.

2.1.1.2. Procedure

2.1.1.2.1. Attach the hinge system to the mounting provision of the test fixture. Hinge attitude must simulate vehicle position (door fully closed) relative to the hinge centreline. For test purposes, the distance between the extreme ends of one hinge in the system to the extreme end of another hinge in the system is to be set at 406 ± 4 mm. The load is to be applied equidistant between the linear centre of the engaged portions of the hinge pin and through the centreline of the hinge pin in the longitudinal vehicle direction. (see Figure 5-2).

2.1.1.2.2. Apply the test load at a rate not to exceed 5 mm/min. until the required load has been achieved. Failure consists of a separation of either hinge. Record the maximum load achieved.

2.1.2. Transverse load test

2.1.2.1. Equipment

2.1.2.1.1. Tensile testing fixture.

2.1.2.1.2. A typical static test fixture is illustrated in Figure 5-1.

2.1.2.2. Procedure

2.1.2.2.1. Attach the hinge system to the mounting provisions of the test fixture. Hinge attitude must simulate vehicle position (door fully closed) relative to the hinge centreline. For test purposes, the distance between the extreme ends of one hinge in the system to the extreme opposite end of another hinge in the system is to be set at 406 ± 4 mm. The load is to be applied equidistant between the linear centre of the engaged portions of the hinge pins and through the centreline of the hinge pin in the transverse vehicle direction. (see Figure 5-2).

2.1.2.2.2. Apply the test load at a rate not to exceed 5 mm/min. until the required load has been achieved. Failure consists of a separation of either hinge. Record the maximum load achieved.

2.1.3.1.2. A typical static test fixture is illustrated in Figure 5-1.

2.1.3.2. Procedure

2.1.3.2.1. Attach the hinge system to the mounting provisions of the test fixture. Hinge attitude must simulate vehicle position (door fully closed) relative to the hinge centreline. For test purposes, the distance between the extreme ends of one hinge in the system to the extreme opposite end of another hinge in the system is to be set at 406 ± 4 mm. The load is to be applied through the centreline of the hinge pin in a direction orthogonal to the longitudinal and transverse loads. (see Figure 5-2).

2.1.3.2.2. Apply the test load at a rate not to exceed 5 mm/min. until the required load has been achieved. Failure consists of a separation of either hinge. Record the maximum load achieved.

2.2. Single hinge evaluation. In some circumstances, it may be necessary to test the individual hinges of a hinge system. In such cases, the results for an individual hinge, when tested in accordance with the procedures below, shall be such as to indicate that system requirements in paragraph 6.1.5.1 of this Regulation are met. (For example, an individual hinge in a two-hinge system must be capable of withstanding 50 per cent of the load requirements of the total system.)

2.2.1. Test procedures

2.2.1.1. Longitudinal load. Attach the hinge system to the mounting provision of the test fixture. Hinge attitude must simulate the vehicle position (door fully closed) relative to the hinge centreline. For test purposes, the load is to be applied equidistant between the linear centre of the engaged portions of the hinge pin and through the centreline of the hinge pin in the longitudinal vehicle direction. Apply the test load at a rate not to exceed 5 mm/min. until the required load has been achieved. Failure consists of a separation of either hinge. Record the maximum load achieved.

2.2.1.2. Transverse load. Attach the hinge system to the mounting provision of the test fixture. Hinge attitude must simulate the vehicle position (door fully closed) relative to the hinge centreline. For test purposes, the load is to be applied equidistant between the linear centre of the engaged positions of the hinge pin and through the centreline of the hinge pin in the transverse vehicle direction. Apply the test load at a rate not to exceed 5 mm/min. until the required load is achieved. Failure consists of a separation of either hinge. Record the maximum load achieved.

2.2.1.3. Vertical load. Attach the hinge system to the mounting provision of the test fixture. Hinge attitude must simulate the vehicle position (door fully closed) relative to the hinge centreline. For test purposes, the load is to be applied centreline of the hinge pin in a direction orthogonal to the longitudinal and transverse loads. Apply the test load at a rate not to exceed 5 mm/min. until the required load is achieved. Failure consists of a separation of either hinge. Record the maximum load achieved.

2.3. For piano-type hinges, the hinge spacing requirements are not applicable and arrangement of the test fixture is altered so that the test forces are applied to the complete hinge.

2. GENERAL PROVISIONS

2.1. Tests are conducted using a full vehicle or a body in white with the sliding door and its retention components.

2.2. The test is conducted using two force application devices capable of applying the outward transverse forces specified in paragraph 6.2.4 of this Regulation. The test setup is shown in Figure 6-1. The force application system shall include the following:

2.2.1.

Two force application plates.

2.2.2.

Two force application devices capable of applying the outward transverse load requirements for a minimum displacement of 300 mm.

2.2.3.

Two load cells of sufficient capacity to measure the applied loads.

2.2.4.

Two linear displacement measurement devices required for measuring force application device displacement during the test.

2.2.5.

3. TEST SETUP

3.1. Remove all interior trim and decorative components from the sliding door assembly.

3.2. Remove seats and any interior components that may interfere with the mounting and operation of the test equipment and all pillar trim and any non-structural components that overlap the door and cause improper placement of the force application plates.

3.3. Mount the force application devices and associated support structure to the floor of the test vehicle. Each force application device and associated support structure is rigidly fixed on a horizontal surface on the vehicle floor, while applying the loads.

3.4. Determine the forward and aft edge of the sliding door, or its adjoining vehicle structure, that contains a latch/striker.

3.5. Close the sliding door, ensuring that all door retention components are fully engaged.

3.6. For any tested door edge that contains one latch/striker, the following setup procedures are used:

3.6.1.

The force application plate is 150 mm in length, and 50 mm in width, and at least 15 mm in thickness. The plate edges are rounded to a radius of 6 mm ± 1 mm.

3.6.2.

Place the force application device and force application plate against the door so that the applied force is horizontal and normal to the vehicle’s longitudinal centreline, and vertically centred on the door-mounted portion of the latch/striker.

3.6.3.

The force application plate is positioned such that the long edge of the plate is as close to, and parallel to, the interior edge of the door as possible, but not such that the forward edge of the plate is more than 12,5 mm from the interior edge.

3.7. For any tested door edge that contains more than one latch/striker, the following setup procedures are used:

3.7.1.

The force application plate is 300 mm in length, and 50 mm in width, and at least 15 mm in thickness. The plate edges are rounded to a radius of 6 mm ± 1 mm.

3.7.2.

3.7.3.

3.8. For any tested door edge that does not contain at least one latch/striker, the following setup procedures are used:

3.8.1.

The force application plate is 300 mm in length, 50 mm in width, and at least 15 mm in thickness.

3.8.2.

3.8.3.

The force application plate is positioned as close to the edge of the door as possible. It is not necessary for the force application plate to be vertical.

3.9. The door is unlocked. No extra fixtures or components may be welded or affixed to the sliding side door or any of its components.

3.10. Attach any equipment used for measuring door separation that will be used to determine separation levels during the test procedure.

3.11. Place the load application structure so that the force application plates are in contact with the interior of the sliding door.

4. TEST PROCEDURE

4.1. Move each force application device at a rate up to 2 000 N per minute, as specified by the manufacturer, until a force of 9 000 N is achieved on each force application device or until either force application device reaches a total displacement of 300 mm.

4.2. If one of the force application devices reaches the target force of 9 000 N prior to the other, maintain the 9 000 N force with that force application device until the second force application device reaches the 9 000 N force.

4.3. Once both force application devices have achieved 9 000 N each, stop forward movement of the force application devices and hold under the resulting load for a minimum of 10 seconds.

4.4. Maintain the force application device position of paragraph 4.3, and within 60 seconds, measure the separation between the exterior edge of the doorframe and the interior of the door along the perimeter of the door.
