Determination of Volume of Empty Test Vessels

Determination	P1 (psig)	P2 (psig)	P3 (psig)	P4 (psig)	Reference Cell Volume (cm^3)	Sample Cell Volume (cm^3)
1	17.385	6.583	17.412	8.629	90.778	148.957
2	17.326	6.563	17.309	8.578	90.914	149.095
3	17.315	6.560	17.456	8.653	90.909	149.044

Mean reference cell volume   :          90.867 cm³
Mean sample cell volume       :          149.032 cm³

Determination of Volume of Test Vessels plus Test Item

1	17.231	6.532	17.274	8.560	91.232	149.433
2	17.228	6.530	17.371	8.612	91.046	149.159
3	17.262	6.542	17.148	8.496	91.183	149.416

Mean reference cell volume   :          91.154 cm³
Mean sample cell volume       :          149.336 cm³

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

Applicant's summary and conclusion

Conclusions:

The density of the test item has been determined to be 938 kg/mE3 at 20.0 ± 1 °C (relative density, 0.938).

Executive summary:

The determination was carried out with a gas comparison pycnometer, 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.

Conclusion

The density of the test item has been determined to be 938kg/m³at 20.0 ± 1°C (relative density, 0.938).
