1、 WORLDWIDE ENGINEERING STANDARDS Material Specification GMW16737 Grease, Silicone Copyright 2012 General Motors Company All Rights Reserved August 2012 Originating Department: North American Engineering Standards Page 1 of 5 1 Scope 1.1 Material Description. This specification defines grease compose

2、d of silicone oil and inorganic thickening agents (amorphous silica, lithium soap, or polytetrafluoroethylene). 1.2 Symbols. Not applicable. 1.3 Typical Applications. Grease defined by this specification may be used on cable connectors, battery terminals, dashboard gauges, rubber door seals, window

3、regulator assemblies, brake calipers, ball joints, cables (trunk/tailgate, accelerator, hood, parking brake), gearshift controls, fuel filler lock doors, air conditioning (A/C) systems, headrests, and as plastic and elastomers assembly aids. 1.4 Remarks. Silicone grease is suitable for use with most

4、 plastics and elastomers. However, this grease should not be used with components made of silicone rubber. This grease will also slightly swell butyl rubber. Consult a materials compatibility chart for specific information. 2 References Note: Only the latest approved standards are applicable unless

Silicone oil (dimethyl or phenyldimethyl polysiloxane) shall be used as the base oil. 3.1.2 Thickener. Amorphous silica, lithium soap, lithium complex, or polytetrafluoroethylene (PTFE) particles shall

7、be used as the thickener. 3.1.2.1 Thickener Designations. The designation for silicone grease containing amorphous silica thickener is ST. The designation for silicone grease containing lithium-based soap thickener (lithium 12-hydroxystearate, or lithium complex) is LT. The designation for silicone

8、grease containing PTFE thickener is PT. 3.1.3 Specific Requirements. The grease shall meet the requirements listed in Appendix A, Table A1 and Table A2.

Grease type, thickener type, and consistency are defined using the following nomenclature: 3XY#, where: 3 means silicone oil-based grease. XY are letters designating thickener types shown in 3.1.2.1. # is

10、a number from one to three (1 to 3) indicating National Lubricating Grease Institute (NLGI) consistency. (Example: 3ST2 is silicone oil-based grease, amorphous silica thickener, NLGI consistency 2.) 4 Manufacturing Process Not applicable. 5 Rules and Regulations 5.1 Legal Regulations. All materials

11、must satisfy applicable laws, rules, regulations and recommendations valid in the country of usage. 5.2 Language. In the event of conflict between the English and domestic language, the English language shall take precedence. 5.3 Inspection and Rejection. All shipments of material or parts under con

12、tract or purchase order manufactured to this specification shall be equivalent in every respect to the initial samples approved by Engineering. There shall be no changes in either formulation or manufacturing processes permitted without prior notification and approval by Engineering. Lack of notific

13、ation by the supplier constitutes grounds for rejection of any shipment. While samples may be taken from incoming shipments and checked for conformance to this specification, the supplier shall accept the responsibility for incoming shipments meeting this specification without dependence upon purcha

14、sers inspection. The series of tests used to approve each batch of product along with acceptance limits will be agreed upon by the purchaser and seller. The laboratory providing the certificate of analysis must also participate in a proficiency testing program (round robin) that is approved by the F

15、uels, Fluids, and Lubricants Global Subsystem Leadership Team (GSSLT) or designate. The Fuels, Fluids, and Lubricants GSSLT or designate must receive copies of the proficiency testing reports directly from the test program administrator. 5.4 Initial Source Approval. No shipment shall be made by any

16、supplier until representative initial production samples have been approved by the Fuels, Fluids, and Lubricants Global Subsystem Leadership Team or designees meeting the requirements of this specification. 5.5 Material Safety Data Sheets/Safety Data Sheets (MSDS/SDS). For new product submissions, o

17、r when a change in chemical composition of an existing product has occurred, a complete copy of the Material Safety Data Sheet/Safety Data Sheet must be submitted in compliance with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) requirements or other country-specifi

18、c MSDS/SDS requirements. In addition, product MSDS/SDS submissions must be in compliance with specific country General Motors TMC003 Material Safety Data Sheet/Safety Data Sheet guidance documents where available. 5.6 All materials supplied to this standard must comply with the requirements of GMW30

19、59, Restricted and Reportable Substances for Parts. 6 Approved Sources Engineering qualifications of an approved source are required for this standard. Only sources listed in the GM Materials File (MATSPC) under this standard number have been qualified by Engineering as meeting the requirements of t
