ASTM D792-2008 用替换法测定塑料密度和比重(相对密度)的试验方法:本标准为ASTM D792-2008，标准的中文名称为用替换法测定塑料密度和比重(相对密度)的试验方法，标准的英文名称为Standard Test Methods for Density and Specific Gravity (Relative Density) of P;astics by Displacement，在2008-06-15开始实施。
本标准作废日期为2013-11-01。被标准ASTM D792-2013替代。
1.1 These test methods describe the determination of the specific gravity (relative density) and density of solid plastics in forms such as sheets, rods, tubes, or molded items. 1.2 Two test methods are described: 1.2.1 Test Method A—For testing solid plastics in water, and 1.2.2 Test Method B—For testing solid plastics in liquids other than water. 1.3 The values stated in SI units are to be regarded as the standard. 1.4 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. Note 1—This standard is not equivalent to ISO 1183–1 Method A. This test method provides more guidelines on sample weight and dimension. ISO 1183-1 allows testing at an additional temperature of 27 ± 2°C.
