The mean relative density of the test item at 20 °C is 1.0449.

The relative density is D420 = 1.045

Conclusions:
According to OECD Test Guideline 109 and Regulation EC No. 440/2008 Part A. Method A.3., the relative density D420 of the test item at 20 °C ± 0.01 °C (compared to water at 4 °C) is D420 = 1.045.
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 1.045.
