(Test Method)Standard Test Methods for Solid Filling and Treating Compounds Used for Electrical Insulation (Withdrawn 2013)
Standard Test Methods for Solid Filling and Treating Compounds Used for Electrical Insulation (Withdrawn 2013)
SIGNIFICANCE AND USE
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.
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 Provide adequate ventilation when these tests involve heating.
1.4 The test methods appear in the following sections:

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 1—There is no similar or equivalent IEC or ISO standard.
WITHDRAWN RATIONALE
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.
Formerly under the jurisdiction of Committee D09 on Electrical and Electronic Insulating Materials, this test method was withdrawn in November 2013. This standard is being withdrawn without replacement because the products referenced in this standard are no longer used in the electrical industry.
