- Conclusions:
- The relative density of the test item was determined to be 1.1514 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 Handbook Vol. 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 1.1514 ± 0.00041 g/cm³ at 20 ± 0.5 °C and the relative density 1.1514 with respect to water at 4 °C, respectively.
