Applicant's summary and conclusion
- Conclusions:
- The relative density D20/4 of the substance was determined to be 1.82.
- Executive summary:
The relative density of the solid substance was determined at 20°C using a gas comparison pycnometer in a GLP study according to EC A.3, OECD 109 and OPPTS 830.7300. From two experiments, the mean (n=2) relative density D20/4 was determined to be 1.82.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
