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.
HFTC4, Operator Seating and Ride Committee is part of the Human Factors Technical Committee. It is responsible for Standards relating to seat dimensions, occupant restraint systems and whole-body vibration transmitted to the operator which is reduced by seat suspensions. The committee is also responsible for testing Standards for durability, ride performance and operator restraint systems. The committee and maintains a Liaison with ISO/TC127, ASABE, and the other HFTC committees as appropriate. Participants in the SAE HFTC4 committee include OEMs, suppliers, consulting firms, government, and others across the construction and agriculture industries
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
