a. Attach a test fixture to the mounting provision of the hinge system. Hinge attitude must simulate vehicle position (door fully closed) relative to the hinge centerline. For test purposes, the distance between the extreme end of one hinge in the system to the extreme end of another hinge in the system is to be set at 406 mm. The load is to be applied equidistant between the linear center of the engaged portions of the hinge pin and through the centerline of the hinge pin in the longitudinal vehicle direction.
b. Apply the test load at a rate not to exceed 50 mm/min until failure. Failure to consist of separation of either hinge. Record maximum load.
Introduction- – In some circumstances, it may be necessary to conduct evaluations of individual hinges in a hinge system. In such cases， the results for an individual hinge, when tested in accordance with the procedures in 6.2, shall be such as to indicate that system requirements in 4.1 and 4.2 are met. (Example: An individual hinge in a two-hinge system must be capable of withstanding 50% of the load requirements of the total system.)
LONGITUDINAL LOAD一Attach a test fixture to the mounting provision of the hinge. Hinge attitude must simulate the vehicle position (door fully closed) relative to the hinge centerline. For test purposes, the load is to be applied equidistant between the linear center of the engaged portions of the hinge pin and through the centerline of the hinge pin in the longitudinal vehicle direction.
TRANSVERSE LOAD一Attach the test fixture to the mounting provision of the vehicle hinge. Hinge attitude must simulate the vehicle position (door fully closed) relative to the hinge centerline. For test purposes, the load is to be applied equidistant between the linear center of the engaged positions of the hinge pin and through the centerline of the hinge pin in the transverse vehicle direction.
Apply the test load at a rate not to exceed 50 mm/min until failure (failure to consist of separation of either hinge). Record maximum load.SAE J934 pdf free download.
