Materials and methods

Test guideline
Qualifier:
no guideline followed
Deviations:
not applicable
Principles of method if other than guideline:
Method utilizes an oscillating densitometer (accepted method per OECD TG109 §13). The density instrument (Anton Paar DMA58) is compliant with ISO standard 15212-1, but it is unknown if the densitometer was calibrated.

Applicant's summary and conclusion

Conclusions:
The relative density of MeDONA is 1.589 at 23 °C
Executive summary:

The relative density of MeDONA was determined using an oscillating densitometer (Anton Paar DMA58) as permitted by test guidance OECD TG 109. The relative density of MeDONA at 23 °C is 1.589. Determining density by an oscillating densitometer is permitted by test guidance OECD TG 109 §13. OECD TG 109 states that the densitometer should be calibrated with two liquids of known density and preferably liquids with densities which span the range into which the investigation falls. The densitometer is compliant with ISO standard 15212-1, but it is unknown if the densitometer was calibrated. The study was not conducted in accord with GLP guidelines. Therefore this study is classified as reliable with restrictions.
