Scope

The melting point is useful in selecting a filling or treating compound that will not flow at the operating temperature of the device in which it will be used. It is also essential that it shall not be so high as to injure the insulation at the time of pouring. This test method is suitable for specification, classification, and for control of product uniformity.

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 Provide adequate ventilation when these tests involve heating.

1.4 The test methods appear in the following sections:

Test Method	Sections
Electrical Tests:
A-C Loss Characteristics and Permittivity (Dielectric Constant)	51-54
Dielectric Strength	42-45
Volume Resistivity-Temperature Characteristics	46-49
Physical Tests:
Coefficient of Expansion or Contraction	22-41
Flash and Fire Points	9 and 10
Loss on Heating	11 and 12
Melting Point	5 and 6
Penetration	15 and 16
Softening Point	7 and 8
Specific Gravity	17-21
Viscosity	13 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 12.1 and 31.5.

Note 18212;There is no similar or equivalent IEC or ISO standard.
