This SAE Recommended Practice establishes for trucks, buses, and multipurpose passenger vehicles with GVW of 4500 kg (10 000 lb) or greater: a. Minimum performance requirements for the switch for activating electric or electro-pneumatic windshield washer systems. b. Uniform test procedures that include 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 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 washing system performance is developed.
The typo is an obvious error since a temperature cannot be 165 degrees C and 74 degrees C at the same time. The conversion was correct but the annotation should have been F rather than C.
