5.1 This standard measures the steady state thermal impedance of electrical insulating materials used to enhance heat transfer in electrical and electronic applications. This standard is especially useful for measuring thermal transmission properties of specimens that are either too thin or have insufficient mechanical stability to allow placement of temperature sensors in the specimen as in Test Method E1225. 5.2 This standard imposes an idealized heat flow pattern and specifies an average specimen test temperature. The thermal impedances thus measured cannot be directly applied to most practical applications where these required uniform, parallel heat conduction conditions do not exist. 5.3 This standard is useful for measuring the thermal impedance of the following material types. 5.3.1 Type I—Viscous liquids that exhibit unlimited deformation when a stress is applied. These include liquid compounds such as greases, pastes, and phase change materials. These materials exhibit no evidence of elastic behavior or the tendency to return to initial shape after deflection stresses are removed. 5.3.2 Type II—Viscoelastic solids where stresses of deformation are ultimately balanced by internal material stresses thus limiting further deformation. Examples include gels, soft, and hard rubbers. These materials exhibit linear elastic properties with significant deflection relative to material thickness. 5.3.3 Type III—Elastic solids which exhibit negligible deflection. Examples include ceramics, metals, and some types of plastics. 5.4 The apparent thermal conductivity of a specimen is able to be calculated from the measured thermal impedance and measured specimen thickness if the interfacial thermal resistance is insignificantly small (nominally less than 18201;%) compared to the thermal resistance of the specimen. 5.4.1 The apparent thermal conductivity of a sample material is able to be accurately determined by excluding the interfacial thermal resistance. This is accomplished by measuring the thermal impedance of different thicknesses of the material under test and plotting thermal impedance versus thickness. The inverse of the slope of the resulting straight line is the apparent thermal conductivity. The intercept at zero thickness is the sum of the contact resistances at the two surfaces. 5.4.2 The contact resistance is able to be reduced by applying thermal grease or oil to the test surfaces of rigid test specimens (Type III). 1.1 This standard covers a test method for measurement of thermal impedance and calculation of an apparent thermal conductivity for thermally conductive electrical insulation materials ranging from liquid compounds to hard solid materials. 1.2x00a0......

1.1 These test methods cover the sampling and testing of electrical insulating boards. These boards are porous, usually fibrous sheets used for dielectric and structural purposes in electrical apparatus. 1.2 These test methods are not intended for testing vulcanized fibre or molded laminated sheets. 1.3 These test methods are applicable to board materials having a nominal thickness of at least 0.030 in. (0.76 mm). NOTE 1—For materials thinner than 0.030 in. (0.76 mm) see Test Methods D202. 1.4 The test methods appear in the following sections: Sections ASTM Method Reference Apparent Density 18 – 23 Aqueous Extract Characteristics 36 – 42 D202 Ash Content 43 – 46 T 413 Compatibility with Dielectric Liquids 47 – 52 D664, D877, D924, D971, D974, D1169, D1500, D1816, D3455, D3487 Compressibility 79 – 85 Conditioning 11 D685 Degree of Polymerization 86 – 89 D4243 Dielectric Strength in Air 53 – 59 D149 Dielectric Strength in Oil 60 – 65 D149, D2413, D3426 Dimensions of Sheets 12 – 17 Moisture Content 31 – 35 D644 Oil Absorption 72 – 78 Reports 10 Sampling 6 – 9 D3636 Shrinkage 24 – 30 D644 Tensile Properties 66 – 71 D202 1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This test method covers the determination of the concentration of pinhole detections in a moisture barrier film or coating that is applied to the interior surface of metal jacketing. 1.2 Since this method relies on the completion through the metal jacketing of an electrical circuit, this method is only applicable to jacketing that is electrically conductive and has a moisture barrier applied which is not electrically conductive. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.
