- Executive summary:
A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 to determine the relative density of the test item. The density was measured at a temperature of 20 °C ± 0.01 °C using the gas comparison pycnometer. Two tests with different amounts of the test item were performed to determine the relative density. The relative density of the test item at 20 °C compared to water at 4 °C was determined to be 1.48 g/cm³.
Reference
Two tests with different amounts of the test item were performed to determine the relative density D420 at a temperature of 20 °C ±0.01 °C.

The mean density of the test item at 20 °C was determined to be 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 (0.9999750 g/cm³). The relative density was determined to be D420 = 1.48.
Description of key information
