- Scope
- 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 D2129 Flash point 7 D92 Fire point 7 D92 Polychlorinated biphenyl content 8 D4059 Pour point 9 D97 Refractive index 10 D1807 Specific gravity 11 D1298, D1481, D4052 Volatility 12 D4559 Viscosity 13 D445, D2161 Chemical: Neutralization number 14 D974 Water content 15 D1533 Electrical: Relative permittivity 16 D9242 Dielectric breakdown voltage 17 D8773 Dissipation factor 18 D9242 Specific resistance 19 D11692 Compatibility 20 D5282 1.5 This standard does not purport to address all of the safety concerns, 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.
