Individual results

Two tests were performed at 20.0 °C. The results are summarised in Table 1.

Table 1: Results of the two tests

Measurement	Density ρp20(g/cm³)
1	1.1516
2	1.1553
Mean	1.16

Conclusions:

The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be 1.16.

Executive summary:

A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.3 and OECD TG 109 by using the oscillating densitometer at 20 °C. Two tests were performed and the density of the test item was determined. The relative density of the test item was determined to be D₄²⁰ = 1.16.

Description of key information

The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be 1.16.

Additional information

A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.3 and OECD TG 109 by using the gas comparison pycnometer a

20 °C. Two tests were performed and the density of the test item was determined. The relative density of the test item (calculated from the mean density of the test item) was determined to be D₄²⁰= 1.16.
