3、uthorized the use of this commercial item description, for all federal agencies. 1. SCOPE. This commercial item description (CID) covers two types of silicone greases that are intended for application as a lubricant, a sealant, and as a preservative in missile systems. 2. CLASSIFICATION. The silicon
4、e grease shall conform to the following types and sizes: 2.1 Types. Type I Light consistency. Type II Medium consistency. 2.2 Sizes. Size A 8 ounce (oz) tube. Size B 10 pound (lb) can. Size C 5.3 oz tube. 3. SALIENT CHARACTERISTICS. 3.1 Material. The silicone grease shall have an unctuous (oily, soa
5、py) consistency that is free of lumps, crusts, or granular particles. METRIC Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59173A 2 3.2 Penetration. The grease shall have the following penetration when tested in accordance with ASTM D217: type
6、I penetration (tenths of a millimeter) range of 300-340; type II penetration (tenths of a millimeter) range of 260-300. 3.3 Foreign particles. The grease shall have the following foreign particle requirements when tested in accordance with FED-STD-791, Method 3005: a. There shall not be more than 75
7、00 particles that are of size 25 microns or greater per cubic centimeter in the grease. b. There shall not be more than 1600 particles that are of size 75 microns or greater per cubic centimeter in the grease. c. There shall not be any particles that are of size 125 microns or greater in the grease.
8、 3.4 Oxidation stability. The oxygen pressure shall not decrease more than 34.47 kilo-Pascals (kPa) during 50 hours of exposure of the material at a temperature of 150C (302F) when tested in accordance with ASTM D942 (an air bath may be substituted for the oil bath). 3.5 Dropping point. The grease s
9、hall have a dropping point greater than 190C (374F) when tested in accordance with ASTM D566 or ASTM D2265. 3.6 Evaporation. The grease shall not lose greater than 3.0 percent of its original weight by evaporation when tested in accordance with ASTM D2595. 3.7 Bleeding. Type I silicone grease shall
10、not lose greater than 5.0 percent of its original weight by bleeding. Type II silicone grease shall not lose greater than 4.0 percent of its original weight by bleeding. The percentage of bleeding of oil from the material shall be determined in accordance with ASTM D6184 except that the heating of t
11、he entire test assembly will be maintained at 150C (302F) for a duration of 24 hours. 3.8 Solidification. The material shall show no evidence of solidification after exposure for 24 hours at a temperature of -55C (-67F). Evidence of solidification shall be tested in accordance with the following tes
12、t procedure: Put 20 millimeters of grease in a 2.54 centimeter (1 in) diameter test tube. Immerse the test tube in a suitable bath and cool to -55C (-67F) for a period of 24 hours. Remove the sample from the test tube and examine for evidence of solidification such as lumps, crusts or granular parti
13、cles. 4. REGULATORY REQUIREMENTS. The offerer/contractor is encouraged to use recovered materials to the maximum extent practicable, in accordance with paragraph 23.403 of the Federal Acquisition Regulation (FAR). Feasibility of using recovered materials must be considered for silicone grease with r
