Applicant's summary and conclusion
- Conclusions:
- The relative density was determined as p20.04.0 = 3.4627
- Executive summary:
The relative density of Synthetic cubic Boron Nitride Grade 2 (2 micron) Powder was determined following OECD 109 and EC method A.3 with an air comparison pycnometer. The relative density was determined as p20.04.0 = 3.4627 using the density of water at 4 °C (0.999972 g/cm3).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
