GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of these specifications. 4.1 ADDITIONAL TESTS FOR INFORMATION ONLY (Used in the development or eval
21、uation of new fluids) 4.1.1 Lubricity Performance (Ford Product Development will evaluate performance) 4.1.2 Copper Corrosion Test (Unpublished Ford test method, Contact Ford Materials Engineering) Test includes heat, moisture, copper and rubber. Test duration is 500 hours and measures the level of
22、copper in the brake fluid. 4.1.3 Viscosity versus Temperature curves for dry fluid and 1%, 2%, and 3% water content. Measure viscosity at -40, -30, -25, -20, -10, and 0 C. 4.2 WARNING This material is hygroscopic; all containers must be air sealed or prevent the admission of moisture through breathi
23、ng devices, as the presence of moisture in minute amounts lowers the boiling point of this material. 4.3 SURVEILLANCE Vehicle Operations Quality Procedure VOPQUG-205, Hydraulic Brake Fluid Surveillance and Control is used to monitor and maintain the quality of the brake fluid in the assembly plant.
