This SAE Standard provides a method to obtain consistent force-deflection data of finished (or unfinished, when specified) cushioned components of seats for off-road work machines as listed in SAE J1116 JUN86. This data may be helpful in maintaining seat comfort characteristics and quality control. There is no intent to establish any acceptance criteria.

This Recommended Practice defines classes of tractors having similar characteristics which affect the vibration transmitted to the operator through the operator seat. This recommended practice establishes input data parameters for conducting operator seat vibration tests for various classifications for agricultural wheeled tractors. The classification is intended to aid in the selection of a seat for a specific tractor model and to reduce the amount of testing necessary to determine compliance with applicable standards and/or recommendations. Classification is based on basic configuration and total mass. Instrumentation and measurement procedures are specified in SAE J1013 JAN80. Test procedures are defined in SAE J1384. This document is in compliance with DIS 5007 adopted by ISO/TC23/SC3 October 1984 in Madrid, Spain.

This SAE Recommended Practice pertains to operator seats for the earthmoving category of off-road self-propelled work machines as defined in SAE J1116 JUN81. This recommended practice defines classes of earthmoving machines having similar characteristics which affect the vibration transmitted to the operator through the operator seat. This recommended practice establishes input data parameters for conducting operator seat vibration tests for the various classes. The purpose is to aid in the selection of an operator seat for a specific machine model and to reduce the amount of testing necessary to determine compliance with applicable standards and/or recommendations. Test procedures are specified in SAE J1384. Instrumentation and measurement procedures are specified in SAE J1013 JAN80.

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 SAE Standard provides performance and test requirements for operator restraint systems provided for off-road self-propelled work machines.

This SAE Standard specifies a method and the device for use in determining the position of the Seat Index Point (SIP) for any kind of seat.
