Calibration

The pressure readings and the calculated volume for the reference and sample cells are shown

in the following table:

Table

Determination	P1 (psig)	P2 (psig)	P3 (psig)	P4 (psig)	Reference cell volume [cm3]	Sample cell volume [cm3]
1	17.418	6.593	17.221	8.531	90.748	148.998
2	17.183	6.510	17.189	8.516	91.071	149.309
3	17.187	6.513	17.177	8.510	91.161	149.402

Mean reference cell volume : 90.993 cm3

Mean sample cell volume : 149.236 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.

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

Mean density : 1.00 x 10³ kg/m3

Relative density : 1.00

Temperature : 20.0 ± 1.0 °C

	C	17.267	7.671	35.409	9.985 x 10^2

Conclusions:

The density of the test item has been determined to be 1.00 x 10^3 kg/m3 at 20.0 ± 1.0 °C (relative density: 1.00).

Executive summary:

The relative density of amidoamine test item was determined in a Klimisch 1 GLP study according to EC A.3 and OECD 109 by using the air comparison pycnometer method. The test item has a relative density of 1.00 at 20 °C which corresponds to 1.00 x 10^3 kg/m ³.

This study is considered relevant for the risk assessment.

Description of key information
