white solid - Key result
- Type:
- relative density
- Density:
- 1.124 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item was determined to be 1.1238 ± 0.00981 (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 1.1238 ± 0.00981 g/cm³ at 20 ± 0.5 °C and the relative density 1.1238 with respect to water at 4 °C, respectively.
