ASTM D176-00

Standard Test Methods for Solid Filling and Treating Compounds Used for Electrical Insulation

SCOPE
1.1 These test methods cover physical and electrical tests for solid filling and treating compounds used for electrical insulation which are fusible to a liquid without significant chemical reaction. Compounds that are converted to the solid state by polymerization, condensation, or other chemical reaction are not included in these test methods.
1.2 These test methods are designed primarily for asphaltic or bituminous compounds, waxes, and fusible resins, or mixtures thereof, although some of these methods are applicable to semisolid types such as petrolatums. Special methods more suitable for hydrocarbon waxes are contained in Test Methods D1168.
1.3 Adequate ventilation must be provided when these tests involve heating.
1.4 The test methods appear in the following sections:Test MethodSectionsElectrical Tests:A-C Loss Characteristics and Permittivity (Dielectric Constant)51-54 Dielectric Strength42-45Volume Resistivity-Temperature Characteristics46-49Physical Tests:Coefficient of Expansion or Contraction22-41Flash and Fire Points9 and 10Loss on Heating11 and 12Melting Point5 and 6Penetration15 and 16Softening Point7 and 8Specific Gravity17-21Viscosity13 and 14
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 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. For specific hazard statements, see Note 4 and Note 7.
Note 1--There is no similar or equivalent IEC or ISO standard.
