- Conclusions:
- The relative density of the test item was determined to be 1.0306 ± 0.00079 (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 six independent determinations. Using the pycnometer method the density was determined to be 1.0306 ± 0.00079 g/cm3 at 20 ± 0.5 °C and the relative density 1.0306 with respect to water at 4 °C, respectively.
Reference
The density of the test item was determined from five replicates at 20 °C with the volume of the pycnometer (24.6707 cm3).
