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 30g 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.

2.3.2.3. Install the equipment used to record door opening.
2.3.2.4. Ensure that the door latch is in the fully-latched position, that the door is tethered, unlocked,
and that the window, if provided, is closed.
2.3.3. Test Directions (see Figure 4-3)
2.3.3.1. Longitudinal Setup 1. Orient the door subsystem(s) on the acceleration device in the
direction of a frontal impact.
2.3.3.2. Longitudinal Setup 2. Orient the door subsystem(s) on the acceleration device in the
direction of a rear impact.
2.3.3.3. Transverse Setup 1. Orient the door subsystem(s) on the acceleration device in the
direction of a driver-side impact.
2.3.3.4. Transverse Setup 2. Orient the door subsystem(s) on the acceleration device in the
direction opposite to that described in Paragraph 2.3.3.3. of this Annex.
2.3.3.5. Vertical Setup 1. (Applicable to doors that open in a vertical direction). Orient the door
subsystem(s) on the acceleration device so that its vertical axis (when mounted in a vehicle)
is aligned with the axis of the acceleration device, simulating a rollover impact where the
force is applied in the direction from the top to the bottom of the door (when mounted in a
vehicle).
2.3.3.6. Vertical Setup 2. (Applicable to doors that open in a vertical direction). Orient the door
subsystem(s) on the acceleration device so that its vertical axis (when mounted in a vehicle)
is aligned with the axis of the acceleration device, simulating a rollover impact where the
force is applied in the direction opposite to that described in Paragraph 2.3.3.5. of this
Annex.
2.4. Test Operation for Options 2 and 3
2.4.1. A minimum acceleration level of 30 g shall be maintained over a period of at least 30 ms,
while keeping the acceleration within the pulse corridor as defined in Table 4-1 and
graphically shown in Figure 4-2.
2.4.2. Accelerate the test fixture(s) in the following directions:
2.4.2.1. For Option 2 tests:
2.4.2.1.1. In the direction specified in Paragraph 2.2.3.1. of this Annex.
2.4.2.1.2. In the direction specified in Paragraph 2.2.3.2. of this Annex.

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 ± 4mm. 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 5mm/min until the required load has been
achieved. Failure consists of a separation of either hinge. Record the maximum load
achieved.
2.1.3. Vertical Load Test (For Doors that Open in the Vertical Direction)
2.1.3.1. Equipment
2.1.3.1.1. Tensile Testing Fixture.
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 ± 4mm. 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 5mm/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% 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 5mm/min until the
required load has been achieved. Failure consists of a separation of either hinge. Record
the maximum load achieved.

The plate edges are rounded to a radius of 6mm ± 1mm.
3.7.2. 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 a point mid-way between the outermost edges of the latch/striker assemblies.
3.7.3. 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 12.5mm from the interior edge.
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 300mm in length, 50mm in width, and at least 15mm in thickness.
3.8.2. 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 a point mid-way along the length of the door edge ensuring that the loading device
avoids contact with the window glazing.
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.
