Test Method: SATRA TM134
Density of materials by volume displacement
October 1998 (2010)
This test specimen is intended to determine the density or ‘specific gravity’ (weight per unit volume) of materials by measuring their volume displacement in water. The method is mainly applicable to rubbers and plastics but can be used with any type of nonabsorbent material.
The test specimen is first weighed in air. It is then reweighed fully immersed in water. The apparent loss in weight is equal to the weight of water displaced. The volume displacement, equal to the volume of the test piece, is then calculated and divided into the weight in air to give the density.
