- Key result
- Type:
- relative density
- Density:
- 1.51 other: relative density
- Temp.:
- 20 °C
- Conclusions:
- Relative density at 20°C was determined 1.51.
- Executive summary:
The relative density of the test item at 20 °C (compared to water at 4 °C) according to the European Commission Regulation (EC) No. 440/2008 and in the OECD 109 was determined to be:
D420 = 1.51
Reference
As the measurement of the density of the test item as it was delivered did not yield stable measurement results, the test item was dried at 105 °C in vacuum. Two test series were performed at 20.0 °C with the dried test item. The results are summarized in Table1.
