Temp.:

20 °C

Two tests were performed at 20.0 °C.

Results of the two tests

Measurement	Density ρPR / g·cm
1	1.1697
2	1.1682
Mean	1.1690

 

Mean density ρPR for the two test series: 1.17 g/cm3

 

The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D₄^R 1.17.

Conclusions:

The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.17.

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 D₄^R 1.17.

Description of key information

The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.17.
