Dynamic Durability Testing of Seat Cushions for Off-Road Work Machines
This SAE Standard describes a laboratory test procedure for comparatively evaluating the durability and fatigue life qualities of a complete seat cushion by submitting the seating surface of the cushion to repetitive compressive and rotational loading with a simulated human buttocks. This document provides a uniform method of dynamically testing the durability of seat cushions on a comparative basis.
