1.1 This practice is intended to define the exposure condi-tions for evaluating the thermal endurance of plastics when exposed solely to hot air for extended periods oftime. Only the procedure for heat exposure is specified. The effect of elevated temperature on any particular property is determined by selection of the appropriate test method and test […]

The choice of method will be dictated by the purpose of the test, type of material, and equipment availability. All methods are applicable to material that is relatively uniform in strength and stiffness properties. Only Method C should be used to test material suspected of having strength or stiffness variations within a panel caused by

1.1 This test method covers the determination of color,whiteness, and yellowness of asbestos by means of a photo-electric reflectometer. 1.2 The test method is applicable to all grades and varieties of homogeneous milled asbestos.

1.1 This test method covers the determination, without reference to a material paint standard, of the hiding power of air dry coatings with Y tristimulus values greater than 15 %.With appropriate modification, it can also be used to test baking finishes. 1.2 The values stated in SI units are to be regarded as standard. No

1.1 This guide covers three procedures for determining the susceptibility of organic-coated metal substrates to formation of filiform corrosion. 1.2 This guide is limited to the determination of whether filiform corrosion will occur between the organic coating and substrate.

1.1 This test method covers the estimation of the equlib-rium solubility of several common gases encountered in the aerospace industry in hydrocarbon liquids. These include petroleum fractions with densities in the range from 0.63 to 0.90 at 288 K (59°F). The solubilities can be estimated over the temperature range 228 K (-50°F) to 423 K

1.1 These test methods cover the measurement of the relative degree of openness or degree of fiberization of milled asbestos fiber by air permeability instruments.

1.1 This test method covers the determination of the coking value of tar and pitch having an ash content not over 0.5 % as determined by Test Method D2415. 1.2 Coking values by this test method are practically the same as those obtained by Test Method D189, but results are more reproducible. The apparatus used

1.1 This specification covers polyethylene (PE) pipe made in standard inside dimension ratios (SIDR) and pressure rated for water (see appendix). Included are requirements for PE compounds and requirements and test methods for workmanship, dimensions, elevated temperature sustained pressure, burst pressure, and marking.

1.1 This test method covers the determination of the com-pressibility of sole leather. This test method does not apply to wet blue. 1.2 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
