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

Table 1: Results of the two tests

Measurement	Density ρPR / g·cm
1	1.2792
2	1.2820
Mean	1.2806

 

Mean density ρPR for the two test series: 1.28 g/cm³

The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.28.

Conclusions:

The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R = 1.28.

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 gas comparison pycnometer at 20.0 °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 D4R = 1.28.
