CALIBRATION

- Pressure readings are shown in Table 6 (below) together with the calculated volume for the reference and sample cells.

- As the reference cell volume and sample cell volume were within the defined tolerances (90.953 ± 1.0 cm3 and 149.225 ± 1.0 cm3 respectively), the gas comparison pycnometer was considered acceptable for use.

Mean density for Determination 1 = 939 kg/m3

Mean density for Determination 2 = 936 kg/m3

Overall mean density = 937 kg/m3

Relative density = 0.937

Temperature = 19 ± 0.5 °C

Conclusions:
The density of the test item was determined to be 937 kg/m3 at 19.0 ± 0.5 °C and the relative density was reported as 0.937.
