Reference
Two tests with different amounts of the test item were performed to determine the relative density D_4^20 at a temperature of 20 °C ±0.01 °C.

Description of key information
According to OECD Test Guideline 109 (2012), Regulation EC No. 440/2008 Method A.3. and EPA OCSPP Test Guideline 830.7300 (2002), the relative density D_4^20 of the test item at 20 °C ± 0.01 °C (compared to water at 4 °C) is D_4^20 = 1.663.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.663
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
