The pycnometer volume was determined using ultrapure water at 20 °C to be 24.1950 cm3.

The density ofthe test item was determined from five replicates at 20 °C with the determined volume of the pycnometer.

The relative density of the test item was determined to be 1.1907 ± 0.00096 (with 95 % confidence interval) at 20 °C.

Conclusions:
The relative density of the test item was determined to be 1.1907 ± 0.00096 (with 95 % confidence interval) at 20 °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. The density was determined in five independent determinations. Using the pycnometer method the density was determined to be 1.1907 ± 0.00096 g/cm3 at 20 °C and the relative density 1.1907 with respect to water at 4 °C, respectively.

Description of key information

The relative density of the test item was determined to be 1.1907 ± 0.00096 (with 95 % confidence interval) at 20 °C.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

A study (reference 4.4-1) 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. The density was determined in five independent determinations. Using the pycnometer method the density was determined to be 1.1907 ± 0.00096 g/cm3 at 20 °C and the relative density 1.1907 with respect to water at 4 °C, respectively.
