- Conclusions:
- The relative density of the test item was determined to be 1.2975 at 20 °C.
- Executive summary:
A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3, OPPTS 830.7300 and CIPAC F MT 3 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 1.2975 ± 0.00742 g/cm³ at 20 ± 0.5 °C and the relative density 1.2975 with respect to water at 4 °C, respectively. The standard deviation reflects the distinguished correlation of the individual determinations.
Reference
The density of the test item was determined from five replicates at 20 °C with the determined volume of the pycnometer (24.2243 cm³ and 24.2609 cm³).
