This SAE Recommended Practice provides the following for the windshield washer system for trucks, buses, and multipurpose vehicles with GVW of 4500 kg (10 000 lb) or greater:

a. Minimum performance requirement

b. Uniform test procedures. The test procedures are limited to those tests that can be conducted with uniform test equipment by commercially available laboratory facilities.

c. Uniform terminology of windshield washer system characteristics and phenomena.

The minimum performance requirements and test procedures, outlined in this document, are based on currently available engineering data.

It is intended that all portions of the document will be periodically reviewed and revised as additional data on windshield washer system performance are developed.
