Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Applicant's summary and conclusion

Conclusions:
The density of sample 20ºC,0.8546 g/cm3, relative density (20/20ºC):0.8561 and relative density (20/4ºC):0.8547 ± 0.0005.
Executive summary:

The density is calculated from the difference in weight between the full and empty pycnometer and its volume. Density of water at 4ºC is the maximum value of density of the water. The water density (theoretical): 0.9999 g/ml. Pyknometer OECD 109 According to method ISO 758, the Gay-Lussac type conforming to the dimension given in ISO 3507 and the water bath temperature 20.0ºC Nominal capacity of 25.703 cm3. The density of sample 20ºC, 0.8546 g/cm3, relative density (20/20ºC), 0.8561 and relative density (20/4ºC), 0.8547 ± 0.0005.
