SCOPE The material defined by this specification is an NLGI Grade 2 synthetic lubricating grease consisting of a fluorosilicone base oil thickened with a fluorinated polymer (PTFE). 2. APPLICATION This s
3、pecification was released originally for a lubricant to be used on vehicle interiors to prevent squeaks between soft materials (e.g., PVC, TPE, Leather, etc.), hard thermoplastics, (e.g., ABS, PA, PC, etc.), ferrous and non-ferrous metals (both painted and unpainted), and combinations thereof. The l
4、ubricant is suitable for operating temperatures between -40 and + 204 C. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1.1 Initial Qualifications
5、 The supplier must furnish to the affected Materials Engineering activity a completed and certified copy of the attached Supplement A and test reports demonstrating the capability of the process for the listed critical properties. 3.1.2 Ongoing Verification Plan In addition to the control plan, the
6、supplier and affected Materials Engineering activity shall establish a mutually agreed upon ongoing product verification plan which will be listed on Supplement B. 3.4 CONSISTENCY Material shall be a smooth homogenous product free from abrasive particles, it shall be consistent in color and texture,
7、 and free from objectionable odors during normal storage. It shall be suitable for the intended application. 3.5 FUNCTIONAL APPROVAL Materials being evaluated for initial approval may be subjected to a functional trial. Functional trial results shall be evaluated by the responsible Systems Engineeri
