ASTM D1168 Standard Test Methods for Hydrocarbon Waxes Used for Electrical Insulation
ASTM D1168电绝缘用烃类石蜡标准试验方法
p>The significance and use of the individual test methods are to be found in the individual methods referenced. For significance specifically applicable to electrical insulation materials, refer to Test Methods D 176.
1. Scope
1.1 These test methods cover a compendium of tests that apply to mineral waxes of petroleum origin in general, but more specifically to the so-called microcrystalline types used as either electrical insulation or moisture-proofing mediums, or both, for treating, impregnating, coating, and filling electrical apparatus. These test methods are also applicable to other waxes of natural or synthetic origin, provided that their characteristics are similar to those of the so-called microcrystalline waxes.
Note 1—There is no equivalent ISO or IEC standard.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.3 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 precautions, see Section 5.
