Result

The following data were determined for test item:

Value-No. 1: 1.4459 g/cm3

Value-No. 2: 1.4461 g/cm3

Value-No. 3: 1.4462 g/cm3

Value-No. 4: 1.4464 g/cm3

Value-No. 5: 1.4464 g/cm3

The mean value for the five individual measurements is: 1.4462 g/cm3

The relative density is calculated by dividing this result by the factor 1.0000 g/cm3.

After rounding the value to three decimal places, the relative density of the test substance is hence: Relative density = 1.446 (standard deviation: ± 0.0002 )

Conclusions:
The relative density of the test substance is 1.446 (standard deviation: ± 0.0002 g/cm3) at 20 °C.
Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item. The density was determined in 5 independent determinations. Using the pycnometer method the relative density was determined to be 1.446 (standard deviation: ± 0.0002 g/cm3) at 20 °C.

Description of key information

Using the pycnometer method the relative density was determined to be 1.446 (standard deviation: ± 0.0002 g/cm3) at 20 °C (reference 4.4 -1).

Key value for chemical safety assessment

Relative density at 20C:
1.446
