Mean density ρP20 for the two test series: 1.48 g/cm3


Relative density (compared to water at 4 °C) D420:


D420 = ρP20 / ρW4 = 1.48 g/cm3 / 1.00 g/cm3 = 1.48 ± 0.01

Conclusions:
The relative density of the test item was determined to be 1.48 at 20 °C.
Executive summary:

A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 using an oscillating densitimeter to determine the relative density D420 of the test item. Two tests with the test item were performed at a temperature of 20 °C ± 0.01 °C. The mean density of the test item at 20 °C was 1.48 g/cm³. The relative density D420 was calculated by dividing the density of the test item by the density of water at 4 °C (1.00 g/cm³). The relative density was determined to be D420 = 1.48.

Description of key information

The relative density of the test item was determined to be 1.48 at 20 °C (reference 4.4-1).

Additional information

A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 using an oscillating densitimeter to determine the relative density D420 of the test item. Two tests with the test item were performed at a temperature of 20 °C ± 0.01 °C. The mean density of the test item at 20 °C was 1.48 g/cm³. The relative density D420 was calculated by dividing the density of the test item by the density of water at 4 °C (1.00 g/cm³). The relative density was determined to be D420 = 1.48.
