SCOPE The material defined by this specification is a NLGI Grade 2 synthetic lubricating grease consisting of a base fluid and fluorinated polymer. 2. APPLICATION This specification was released originally for grease used
3、on bearings for windshield wiper motors. The lubricant is suitable for operating temperatures between - 15 and + 200 C. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials

GENERAL INFORMATION The information given below is pro
5、vided for clarification and assistance in meeting the requirements of this specification. Grease approved to this specification should have the following typical properties. 4.1 COLOR White (Visual) 4.2 BASE FLUORINATED POLYMER 15 20% (According to formulation, ASTM D 128) 4.3 OIL VISCOSITY INDEX 12
6、4 (ASTM D 2270) 4.4 DROPPING POINT (ASTM D556, ASTM D 2265, DIN ISO 2176) Not Available The test gives inaccurate results on solid thickened greases and would show a drop of oil from the tester at temperatures under 200 C even for greases that work at higher temperatures.

10、on of this grease. PFPE / PTFE lubricants are generally inert to painted surfaces. Grease must be tested for chemical attack to painted surfaces for applications that come in contact with paint surfaces, ex. E-coat and powder coat. 4.11.2 Resistance to Stress Cracking (FLTM BO 127-03) Note: Not test
