Test Method 1 (Braking)

WARNING: It is important that during this test, the driver and passenger allow the safety belts to provide the restraint and do not attempt to anticipate the sudden deceleration. The steering wheel should not be used as a brace. However, both driver and passenger should prepare themselves for the possibility that the safety belt will not lock. The passenger should hold their hands in front of them, just clear of the instrument panel or front seat backrest, depending on which safety belt is being tested. Failure to follow these instructions may result in personal injury.

Select for this test a quiet or private stretch of road. Make sure that the road is clear and that full visibility is maintained at all times.
Both driver and passenger should adopt a normal, comfortable seating position. Both occupants should wear the safety belts and the safety belt webbing must be correctly adjusted, with no slack.
Proceed at a speed of 10 km/h (6 mph). Do not exceed 10 km/h (6 mph) for this test.
Apply the foot brake sharply to stop the vehicle. If the vehicle motion sensitive lock mechanism is operating correctly, the safety belt webbing will lock and restrain the wearer.
Conduct the test twice in each front and rear passenger seat position.
Any safety belt retractor which does not restrain the wearer during this test must not be reused. A new safety belt must be installed.
