The relative density of the test item at 20 °C was 0.9830.

Conclusions:
The relative density of the test item was determined to be 0.983 at 20 °C compared to water at 4 °C.
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. Therefore the density was measured at a temperature of 20 °C ± 0.01 °C using the oscillating densitometer. An initial calibration with purified-water was carried out. Subsequently three independent measurements of the test item were performed. The mean relative density of the test item at 20 °C with respect to water at 4 °C was determined to be 0.983.

Additional information

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. Therefore the density was measured at a temperature of 20 °C ± 0.01 °C using the oscillating densitometer. An initial calibration with purified-water was carried out. Subsequently three independent measurements of the test item were performed. The mean relative density of the test item at 20 °C with respect to water at 4 °C was determined to be 0.983. No observations were made which cause doubt on the validity of the outcome of the study.
