J374_201503 Vehicle Roof Strength Test Procedure

This SAE Recommended Practice establishes a uniform laboratory test method to evaluate the strength characteristics of roof systems. The test procedure is intended to provide reliable and repeatable results and to permit numerical comparisons.

A test is conducted in which the vehicle roof system is loaded under controlled laboratory conditions.

Structural strength measurements are obtained under load application angles chosen to concentrate forces on the forward portions of the roof panel and roof supporting structure.
