Temp.:
20 °C

Three runs were performed:

Run 1: Batch 56035 1.1960 g/cm3 at 20 °C

Run 2: Batch 56631 1.1954 g/cm3 at 20 °C

Run 3: Batch 58208 1.1950 g/cm3 at 20 °C

1. Run 1.1960 g/cm3

2. Run 1.1954 g/cm3

3. Run 1.1950 g/cm3

Mean Value: 1.1955 g/cm3 with standard deviation 1.1955 +/- 0.0005 g/cm3 at 20 °C.

Conclusions:
Under the study conditions, the density of the test substance was assessed to be 1.1955 g/cm3 with standard deviation 1.1955 +/- 0.0005 g/cm3 at 20 °C.
Executive summary:

A study was conducted to determine the density of the test substance using an oscillating densitometer according to OECD Guideline 109 and EU Method A.3. Three independent measurements were conducted at 20 °C. Under the study conditions, the density of the test substance was assessed to be 1.1955 g/cm3 with standard deviation 1.1955 +/- 0.0005 g/cm3 at 20 °C (Stannek, 2017).

Description of key information
