Product Code:SAE J689
Title:Curbstone Clearance, Approach, Departure, and Ramp Breakover Angles--Passenger Car and Light Truck
Issuing Committee:Human Accom And Design Devices Stds Comm
Scope: This SAE Recommended Practice applies to rigid bumper or rigid structure points and flexible components of passenger cars, multipurpose passenger vehicles, and ligh trucks. This document is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. The purpose of this document is to provide minimum static design guidelines for curbstone clearnace, approach, departure, and ramp breakover angles. This is to minimize damage, if any, in normal vehicle use conditions. This document also encompasses all current worldwide regulations and requirements.
