What is ASTM D792?
ASTM D792: Standard Test Methods for Density and Speciﬁc Gravity (Relative Density) of Plastics by Displacement. This standard test method allows for measurement of the density and specific gravity of plastic materials by the buoyancy in a liquid, such as water.
Why is density importance in plastic testing?
Scope: Density is the mass per unit volume of a material. Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and a lower density or specific gravity means more material per pound or varied part weight. …

What is ASTM d1505?
1.1 This test method covers the determination of the density of solid plastics. 1.2 This test method is based on observing the level to which a test specimen sinks in a liquid column exhibiting a density gradient, in comparison with standards of known density.

Is the ASTM d792-13 standard method equivalent to ISO 1183?
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. 2. Referenced Documents (purchase separately)
