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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results
Check of the Densitometer
The apparatus was checked with ultra-pure water. The check of the
apparatus showed that the instrument worked correctly and was fit for
purpose.
Sample Measurement
The density of the test item was determined twice with independently
prepared samples. The data, the mean of the densities, and its relative
deviation are presented in Table 1.
