Calibration

The pressure readings and the calculated volume for the reference and sample cells are shown in the following table:

Table 2

Determination	P1(psig)	P2 (psig)	P3(psig)	P4(psig)	Reference Cell Volume (cm^3)	Sample Cell Volume (cm^3)
1	18.156	6.876	17.679	8.757	90.983	149.256
2	17.518	6.631	17.960	8.897	90.759	149.012
3	17.231	6.521	17.166	8.500	90.806	149.138

 

Mean reference cell volume : 90.849 cm³

Mean sample cell volume : 149.135 cm³

As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm³and 149.225 ± 1.0 cm³for the reference and sample cell volumes respectively) the gas comparison pycnometer was therefore considered acceptable for use.

Sample

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

	B	17.378	7.463	28.4	1.05 x 10^3
	C	17.472	7.502	28.4	1.06 x 10^3

	C	17.568	7.672	32.0	1.06 x 10^3

Mean density : 1.06 x 103 kg/m³

Relative density : 1.06

Temperature : 20.0 ± 0.5 °C

Discussion

Duplicate determinations were performed to ensure a reproducibility of less than ± 20 kg/m³was obtained.

Conclusion

The density of the test item has been determined to be 1.06 x 103 kg/m³at 20.0 ± 0.5 °C and a relative density of 1.06.

Applicant's summary and conclusion
