- Key result
- Type:
- relative density
- Density:
- 4.18
- Temp.:
- 20 °C
- Conclusions:
- Relative density at 20°C: 4.18
- Executive summary:
The relative density of the test item at 20 °C (compared to water at 4 °C) was determined compliant to GLP according to the European Commission Regulation (EC) No. 440/2008 method A.3 and OECD 109:
D420 = 4.18
Reference
Two test series with different weights were performed at ambient temperature (20.0 °C). Results are given in the following table. Due to fluctuation of the results two measurement series with 20 cycles were performed. The first 10 cycles each were used to establish an equilibrium. The results were measured for the cycles 11 to 20.
