Applicant's summary and conclusion
- Conclusions:
- The density of the test item has been determined to be 1.12 x 10³ kg/m³ at 20.0 ± 0.5 °C and a relative density of 1.12.
- Executive summary:
Density was determined to 1.12 x 10³ kg/m³ at 20.0 ± 0.5 °C, relative density of 1.12, using the pycnometer method, designed to be compatible with Method A.3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
