3、RIALS Material suppliers and part producers must conform to the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). 3.2 FINISHED PARTS Testing must be done on actual production parts or a section of the part whenever possible. Where part dimensions limit equipment access, repre

4、sentative panels or plaques may be substituted for production parts. Production parts, panels, and plaques shall be referred to as “specimens“ throughout the specification. 3.3 TYPES OF WWS The type of WWS fluids used in the testing will depend on the market that the vehicle is intended to be sold.

5、If the vehicle is being sold in several markets the fluids representative of each market must be tested. 3.4 TESTING REQUIREMENTS All of the requirements listed in section 3.5 - 3.10 must be performed in triplicate. All weights should be to the nearest milligram. Approximately 3.8 L of windshield wa

6、sher solvent is needed to meet the testing requirements of this specification. The ratio of water to alcohol-based concentrates for final initial fill use will be determined by local market requirements. Contact the Design and Release Engineer for dilution rate.
