- Conclusions:
- According to OECD Test Guidelines 109 (1995) and EC 440/2008 Part A. Method A.3., the relative density D of the test item Dimethoxydiphenyliodoniumbromid at 20 °C ± 0.5 °C (compared to water at 4 °C) is D420= 1,82.
- Executive summary:
The relative density is 1,82 at 20 °C.
Reference
Five tests with different amounts of the test item were performed to determine the relative density D420at a temperature of 20 °C ±0.5 °C. Table1 summarises the results.
