CONTAINED IN VOL. 10.03, 2015 Defines the testing of silicone fluids for use in transformers, capacitors, and electronic assemblies as an insulating or cooling medium, or both.

1.1 These test methods cover the testing of silicone fluids for use in transformers, capacitors, and electronic assemblies as an insulating or cooling medium, or both. These methods are generally suitable for specification acceptance, factory control, referee testing, and research.

1.2 Although some of the test methods listed here apply primarily to petroleum-based fluids, they are, with minor revisions, equally applicable to silicone fluids.

1.3 Silicone fluids are used for electrical insulating purposes because of their stable properties at high and low temperatures and their relative environmental inertness.

1.4 A list of the properties and standards are as follows:

Property Measured Section ASTM Test Method Physical: Color 6 D 2129 Flash point 7 D 92 Fire point 7 D 92 Polychlorinated biphenyl 8 D 4059 content Pour point 9 D 97 Refractive index 10 D 1807 Specific gravity 11 D 1298, D 1481, D 4052 Volatility 12 D 4559 Viscosity 13 D 445, D 2161 Chemical: Neutralization number 14 D 974 Water content 15 D 1533 Electrical: Relative permittivity 16 D 924 2 Dielectric breakdown 17 D 877 3 voltage Dissipation factor 18 D 924 2 Specific resistance 19 D 1169 2 Compatibility 20 D 5282

1.5This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
