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.

1.1 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.
