Results

Calibration

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

  

Determination	P1 (psi)	P2 (psi)	P3 (psi)	P4 (psi)	Reference Cell Volume (cm^3)	Sample Cell Volume (cm^3)
1	17.278	6.539	17.429	8.627	90.929	149.332
2	17.410	6.590	17.550	8.688	90.952	149.333
3	17.639	6.678	17.153	8.490	91.080	149.495

 

Mean reference cell volume: 90.987 cm³
Mean sample cell volume: 149.387 cm³

As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm³and 149.225 ± 1.0 cm³, respectively) the gas comparison pycnometer was therefore considered acceptable for use.

Sample

The pressure readings and volumes obtained for the vessel and the vessel containing test item are shown in the following table:

 

Determination	Test	Vessel			Vessel and Test Item
		P1(sample) (psig)	P2(sample) (psig)	Volume (cm^3)	P3(sample) (psig)	P4(sample) (psig)	Volume (cm^3)
1	A	17.063	6.865	14.225	16.973	7.938	45.826
	B	17.454	7.020	14.150	17.412	8.146	45.890
	C	17.200	6.920	14.221	17.179	8.038	45.914
2	A	17.643	7.110	14.595	17.804	8.356	46.509
	B	17.254	6.950	14.490	17.227	8.083	46.456
	C	17.307	6.970	14.447	17.051	8.001	46.470

Applicant's summary and conclusion

Conclusions:

Please see conclusion within the Executive summary below.

Executive summary:

The determination was carried out by gas comparison pycnometer, using a procedure designed to be compatible with Method A3 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.

Instrument: Gas comparison pycnometer (Multi-Pycnometer, Quantachrome, Syosset, N.Y., USA).

Calibration sphere: A stainless steel sphere with a calibrated known total volume (V_cal= 56.559 cm³).

Gas: Helium.

Test conditions: Determinations performed at 20.0°C ± 0.5 °C.

Conclusion

The density of the test item has been determined to be 973 kg/m³at 20.0 ± 0.5 ºC. The corresponding relative density has been calculated to be 0.973.
