The relative density of the test item was determined to be 1.0967 ± 0.00078 (with 95 % confidence interval) at 20 °C.

Conclusions:
The relative density of the test item was determined to be 1.0967 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 1.0967 ± 0.00078 g/cm3 at 20 ± 0.5 °C and the relative density 1.0967 with respect to water at 4 °C, respectively.

Description of key information

The relative density of the test item was determined to be 1.0967 at 20 °C.
