The scope of this SAE Recommended Practice is to establish uniform test procedures and minimum performance requirements for passenger car windshield washer systems. This recommended practice also provides a uniform terminology of windshield washer system characteristics and phenomena. The test procedures are limited to those tests that can be conducted on uniform test equipment by commercially available laboratory facilities. The test procedures and minimum performance requirements, outlined in this recommended practice, are based on currently available engineering data. It is the intent that all portions of the recommended practice will be periodically reviewed and revised as additional data on windshield washer system performance are developed.
