 Results
Relative Density
Two tests with different amounts of the test item were done to determine the relative density D₄²⁰at a temperature of 20 °C ± 0.01 °C.

Table 1 – Results

Test no.	Temperature [°C]	Amount of test item [g]	Average sample volume [cm^3]	Density [g/cm^3]
1	20	6.81	2.40817	2.82788
2	20	6.80	2.47460	2.74791

 

The mean density of the test item at 20 °C is 2.7879 g/cm³.The relative density D₄²⁰ is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).

The relative density is           D₄²⁰ = 2.79.
