Any other information on results incl. tables
The density ρ of the test item was calculated based on the ratio of the mass of test item to the mass of water used to fill the pycnometer using the following equation:
ρ = d(c-a)/(b-a)
Where: a - mass of pycnometer (g); b - mass of pycnometer filled with water (g); c - mass of pycnometer filled with test item (g); d - density of water at test temperature (kg/m³).

Relative density D(20,4) is calculated using the following equation:
D = ρ/(999.97 kg/m³)
where 999.97 kg/m³ is the density of water at 4 °C (CRC Handbook of Chemistry and Physics, 93rd Edition 2012-2013).
Applicant's summary and conclusion
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
