Note: Nothing in the specification supersedes applicable laws and regulations unless specific exemption has been obtained.

Purpose.

To determine the door slam durability of door structures, components, and related systems.

Foreword.

There are two (2) methods of performing door slam durability testing for those door systems to which this test applies (see 1.3).

This procedure describes actuation using a linear, pneumatic cylinder mounted to the interior of the test body. See GMN5159TP for an accelerated slam durability test utilizing an electrohydraulic/electromagnetic shaker.

The pneumatic method (GMN6540TP) is used for validation. The accelerated method (GMN5159TP) is used for the prediction of structural fatigue of the door inner panel.

Applicability.

This procedure applies to all passenger, multi-purpose and commercial vehicles having conventional swing open door systems, and may also apply to single- or dual-acting endgate systems. The fixtures referenced in this procedure work on any door system, which swings approximately parallel to the ground.
