Results and discussion
Density
- Key result
- Type:
- relative density
- Density:
- 0.958 other: relative density is dimensionless
- Temp.:
- 20 °C
- Remarks on result:
- other: The relative density is given as the mean value of three measurements. The relative density is calculated by dividing the density of the test item by the density of water at 4 °C.
Any other information on results incl. tables
| Test No. | Temperature [°C] | Relative Density |
| 1 | 20 | 0.9586 |
| 2 | 20 | 0.9584 |
| 3 | 20 | 0.9583 |
The mean relative density of the test item at 20 °C is 0.9584.
The relative density is D420 = 0.958
Applicant's summary and conclusion
- Conclusions:
According to OECD Test Guideline 109 (2012), Regulation (EC) No 440/2008 Method A.3. and EPA OCSPP Test Guideline OPPTS 830.7300 (2002), the relative density of the test item 4,4-dimethyloxazolidine (CAS no. 51200-87-4) at 20 °C ± 0.01 °C (compared to water at 4 °C) is 0.958.- Executive summary:
According to OECD Test Guideline 109 (2012), Regulation (EC) No 440/2008 Method A.3. and EPA OCSPP Test Guideline OPPTS 830.7300 (2002), the Relative Density D420 of the test item 4,4-dimethyloxazolidine (CAS no. 51200-87-4) at 20 °C ± 0.01 °C (compared to water at 4 °C) is determined to be: D420 = 0.958
