Discussion
Due to instability of the test material towards water (and water in the atmosphere), the test was carried out under a nitrogen atmosphere.
Applicant's summary and conclusion
- Conclusions:
- The relative density of the test material has been determined to be 0.906 at 20.0 ± 0.5°C.
- Executive summary:
The relative density was determined using the pycnometer method, Method A3 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
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).
