Any other information on results incl. tables

Calibration:

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

Determination	P1(psig)	P2(psig)	P3(psig)	P4(psig)	Reference Cell Volume (cm^3)	Sample Cell Volume (cm^3)
1	17.153	6.495	17.170	8.509	90.772	148.952
2	17.184	6.509	17.158	8.502	90.942	149.148
3	17.170	6.507	17.200	8.525	91.062	149.224

Mean reference cell volume: 90.925 cm³

Mean sample cell volume: 149.108 cm³

As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm3 and 149.225 ± 1.0 cm3 for 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:

Determination	Replicate	P1(sample) (psig)	P2(sample) (psig)	Volume (cm^3)	Density (kg/m^3)	Mean Density (kg/m^3)
1	A	17.190	7.139	21.1	1.50 x 10^3	1.50 x 10^3
	B	17.182	7.136	21.1	1.50 x 10^3

Applicant's summary and conclusion

Conclusions:

The density of the test item has been determined to be 1.50 x 10E3 kg/m3 at 20.0 ± 0.5 °C and a relative density of 1.50.

Executive summary:

Density determination was carried out by the gas comparison pycnometer method, using a procedure designed to be compatible with Method A.3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012.

The density of the test item has been determined to be 1.50 x 10³ kg/m³ at 20.0 ± 0.5 °C and a  relative density of 1.50.
