Windshield Wiper Systems - Trucks, Buses, and Multipurpose Vehicles
J198_202006
This SAE Recommended Practice establishes testing methods and performance requirements for windshield wiping systems on trucks, buses, and multipurpose passenger vehicles with a GVWR of 4500 kg (10000 pounds) or greater and light duty utility vehicles with a GVWR of less than 4500 kg (10000 pounds).
The test procedures and minimum performance requirements, outlined in this document, are based on currently available engineering data.
It is the intent that all portions of the document will be periodically reviewed and revised as additional data regarding windshield wiping system performance are developed.
Rationale:
This revision replaces the SAE eyellipse as a means of anchoring the target viewing area construction planes with a similar, but much simpler, method. The new method reduces the complexity of the construction effort while producing results that are well within the test method tolerance. The windshield wiper coverage requirements in the previous version of this standard could not be met for certain configurations of cabs. There were also no accommodations for single occupant cabs or those with the driver centered in the cab. This document corrects these shortcomings to better fit the breadth of current vehicle designs. Definitions were revised for accuracy and consistency.
