- Type of method:
- air comparison pycnometer (for solids)
- Key result
- Type:
- relative density
- Density:
- 1.35 other: dimensionless
- Temp.:
- 20.1 °C
- Conclusions:
- The relative density at ambient temperature (compared to water at 4 °C) was determined to be 1.35.
- Executive summary:
A study was conducted according to Regulation (EC) No 440/2008 method A.3 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 1.35 ± 0.01 g/cm3 at 20.1 °C and the relative density 1.35 with respect to water at 4 °C respectively.
Reference
Two test series with different weights were performed at ambient temperature (20.1 °C).
