ASTM D-792 : Standard Test Methods for Density and Specific Gravity
(Relative Density) of Plastics by Displacement.
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.
Two test methods are descibed :
Test Method A-For testing solid plastics in water,
And,
Test Method B-For testing solid plastics in liquids other than water.
Note 1 : Alternatively, test method D 1505 may be applied to many such
