Any other information on results incl. tables

The relative density of the test material has been determined to be 1.75 at 21.2 ± 0.5°C.

The pressure readings, calculated volumes and density values obtained for the test material are shown in the following table:

Determination	P1	P2	Volume (cm^3)	Density
A	17.501	7.677	32.835	1.75 x 10^3
B	17.629	7.737	32.939	1.75 x 10^3

Temperature:            21.2 ± 0.5°C

Mean density:           1.75 x 10³ kg/m³

Relative density:        1.75

The relative density was calculated using Equation 6.1 to Equation 6.3.

Equation 6.1

V= V_C- V_R[(P₁/P₂)-1]
