Applicant's summary and conclusion
- Conclusions:
- The relative density D20/4 of the substance was determined to be 1.30.
- 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. The relative density D20/4 was determined in duplicate obtaining a mean value of 1.30.
