Scope
Communicate the process of accurately measuring sound power levels of positive displacement hydraulic pumps commonly used in ground vehicle steering systems. This recommended practice defines the pump mounting (pulley, belt tension, isolation), operating conditions (fluid, speed, temperature, pressure), room acoustics, instrumentation, noise measurement technique and data acquisition setup to be used. Included are recommendations for test sample size, and format for data presentation/reporting.
Rationale
Not applicable.

Issuing Committee
Vehicle Performance Steering Committee
The Vehicle Performance Steering Committee is an oversight committee reporting to the SAE Motor Vehicle Council. The Steering Committee oversees four technical committees related to vehicle dynamics and performance. The steering committee has the authority to establish appropirate committees to develop and maintain technical reports and to discharge committees when assignments are completed.

* 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.
