- Key result
- Type:
- relative density
- Density:
- 1.006 other: dimensionless
- Temp.:
- 20 °C
- Remarks on result:
- other: Standard deviation: 0.0013
- Conclusions:
- The mean relative density of the test substance Wasox-MMAC2 was determined to 1.0056 at 20.0 ºC (standard deviation 0.00013, three replicates).
- Executive summary:
The relative density of "Wasox-MMAC2" was determined according to OECD guideline 109 by a pycnometer method according to Gay-Lussac DIN 12797. The density is calculated from the difference in mass between the full and empty pycnometer and its known volume. The mean relative density of the test substance Wasox-MMAC2 was determined to 1.0056 at 20.0 ºC (standard deviation 0.00013, three replicates).
