The scope of this SAE Recommended Practice establishes for passenger cars, light trucks, and multipurpose vehicles with GBW or 4500 kg (10 000 lb) or less:

a. Minimum performance standards for windshield wiper systems.

b. Test procedures that can be conducted on uniform test equipment by commercially available laboratory facilities.

c. Uniform terminology of windshield wiper system characteristics and phenomena consistent with those found in guides for the use of engineering layout studies to evaluate system performance.

d. Guides for the design and location of components of the systems for function, servicing of the system, etc.

The test procedures and minimum performance standards, outlined in this document will be periodically reviewed and revised as additional data regarding windshield wiping system performance are developed.
