ASTM D792-08 Standard Test Methods for Density and Specific Gravity (Relative Density) of Plastics by Displacement
ASTM International / 15-Jun-2008 / 6 pages ASTM D792-08
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 ASTM D792-08 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.
Keywords: density; relative density; specific gravity; Density–plastics; Displacement–plastics; Specific gravity–plastics; ICS Number Code 83.080.01 (Plastics in general)
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
