APPLICATION This material is primarily intended for use as a hydraulic fl
3、uid in passenger and light commercial vehicle brake systems. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requi
4、rements For Production Materials (WSS-M99P1111-A). 3.2 QUALIFICATION PROCEDURE 3.2.1 Qualification The Materials Engineering activity reserves the right to subject materials submitted against this specification, to any additional investigation they may consider necessary and use the data derived for
5、 approval qualification. 3.2.2 Verification The affected Materials Engineering activity reserves the right to conduct verification testing. If the test results do not support the originally submitted data, the supplier must retest the product in coordination with the affected Materials Engineering a
6、ctivity. This re-test must be conducted and certified by a mutually agreed upon test facility. 3.2.3 Documentation Supplier must furnish to the affected Materials Engineering activity a completed and certified copy of the attached Supplement A and test reports demonstrating full compliance with all
7、the requirements of this specification. All tests must be certified by a qualified and authorized representative of the test facility.

A corrosion test shall be
10、carried out according to SAE J1703 procedure, but including a zinc test strip additional to the six regular SAE strips. The zinc to be placed at the end of the assembly next to the copper strip. The zinc used shall be SAE 925 alloy. Test pieces can be obtained from Erich Herrmann and Co., 7501 Grotz
11、ingen ueber Karlsruhe 2, West Germany. The maximum permissible weight loss for zinc test strip in the test shall be 0.20 mg/cm2 of surface. The test strips outside the contact area shall not be pitted or roughened to an extent visible to the naked eye. 3.2.4.6.2 Graphite Corrosion Test (Appendix A)
12、Any etching, roughening or pitting visible to the naked eye shall constitute a failure. 3.2.4.6.3 Thermal Stability Corrosion Test After 5 days at 100 C in 1 liter sealed can, fluid shall meet the requirement of corrosion test 3.2.4.6.1. 3.2.4.7 Compatibility Using the procedure described in SAE J17
13、03 but supplement RM66-03 compatibility fluid with other Ford approved brake fluids, as required. ENGINEERING MATERIAL SPECIFICATION WSS-M6C57-A2 Copyright 2012, Ford Global Technologies, LLC Page 3 of 7 3.2.4.8 Compliance The brake fluid is an integral component of the hydraulic brake system. Compl
14、iance with the requirements of all E.S. Test Specifications as identified by the relevant Product Engineering office is necessary for the approval of any new fluid against this specification. 3.2.5 Quality Control Upon engineering approval, supplier and affected Materials Engineering activity shall
15、establish mutually agreed upon quality control limits, to be listed on Supplement B, and will be used for ongoing product verifications at mutually agreed upon frequencies. 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of
16、this specification. 4.1 ENVIRONMENTAL CONTROL The supplier shall divulge to the Company, the identity or nature of any ingredient or constituent of their products which is capable of causing pollution of water, air or soil, and/or which is subject to special notification or control under the laws or
17、 regulations in force at the locations in which it is to be used or disposed. In addition, the supplier shall, in appropriate cases, make available to the Company, details of treatment methods that will enable used or surplus material to be broken down satisfactorily for disposal through effluent pl
18、ants. 4.2 HEALTH AND SAFETY This material is potentially harmful unless handled properly. To ensure that appropriate precautions are taken, plant medical and safety units shall be advised of its intended use in the plant. Areas where this material is to be stored and used shall be clearly marked by
19、signs in accordance with Manufacturing Standard U-SN001. 4.3 DISPENSING Care should be exercised when dispensing this material. Brake fluids damage vehicle body paint and certain plastics.

20、DIX A GRAPHITE CORROSION TEST Two shortened SAE cast iron strips are prepared in accordance with SAE J1703. Powdered graphite is applied to the upper surface of the prepared strips to occupy the central area. (Approximately 8 mm x 30 mm to depth of 3 mm). The strips are carefully placed in the test
21、jars (approximately 84 mm OD x 74 mm high) containing 75 ml of the test fluid, (ie fluid under test +5% water +50 ppm chloride derived from NaCl) and the test jars closed with a mild steel lid (without insert pad). The test jars are placed in an oven at 70 +/- 2 C for 168 hours (7 days). At the end
22、of the test period each strip is removed, washed in 95% ethanol to remove the graphite, wiped clean and examined for sings of etching or corrosion pitting under the graphite layer. Any etching, roughening or pitting visible to the naked eye shall constitute a failure. Details of suitable powdered gr
23、aphite can be obtained from the Materials Laboratory 13/100, Laindon, Basildon, Essex SS15 6EE.
