Mean density ρPR for the two test series: 1.411 g/cm³

Relative density (compared to water at 4 °C) DR4:

DR4 = ρPR / ρW4 = 1.411 g/cm³ / 1.000 g/cm³ = 1.411

Conclusions:
The relative density of the test substance was determined to be 1.41.
Executive summary:

A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item. The density was determined in two runs each with three measurements. Using the air comparison pycnometer method the density was determined to be 1.41 g/cm³ at 21.4 °C and the relative density 1.41 with respect to water at 4 °C, respectively.

Description of key information

The relative density of the test substance was determined to be 1.41.

Key value for chemical safety assessment

Relative density at 20C:
1.41

Additional information

A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item. The density was determined in two runs each with three measurements. Using the air comparison pycnometer method the density was determined to be 1.41 g/cm³ at 21.4 °C and the relative density 1.41 with respect to water at 4 °C, respectively (reference 4.4-1).
