Product Code:SAE J1013
Title:Measurement of Whole Body Vibration of the Seated Operator of Off-Highway Work Machines (Cancelled Nov 2007, Superseded by ISO 2631)
Issuing Committee:Hftc4, Operator Seating And Ride
Scope:This SAE Standard defines a method for the measurement of the whole body vibration to which the seated operator of off-highway self-propelled work machines is exposed while performing an actual or simulated operation. It applies to vibration transmitted to the operator through the seat. There are not equivalent ISO Standards. In the main body of this document, conditions are defined for measuring and recording whole body vibration of the seated operator of off-highway self-propelled work machines. The specification of instruments, analytic methods, and description of site and operating conditions allows the measurements to be made and reported with an acceptable precision. The procedure includes means of weighing the vibration level at different frequencies as specified in ISO2631. A standard format for reporting spectral data is recommended. The definitions, instruments, and analytic methods also apply to simulated tests for operator vibration as performed in laboratories. This procedure is a measuring method only and is not intended for the evaluation or selection of seating systems.
