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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Determining the Density of the Sample
Run Number 1 | 1 | 2 |
Mass of Empty Pycnometer (g) | 23.92 | 23.92 |
Mass of Sample & Pycnometer (g) | 30.28 | 29.58 |
Mass of Sample added to empty Pycnometer (g) ms | 6.36 | 5.66 |
Mass of Sample, Pycnometer & immersion liquid | 48.33 | 48.37 |
Mass of immersion liquid added (g) m2 | 18.05 | 18.80 |
Calculated Density of Sample (g/cm3) | 1.003 | 1.016 |
Density of Sample (kg/m3) | 1003 | 1016 |
Mean Result (kg.m-3) | 1009 | |
Density = (ms x density IL ) / (m1 – m2)
Where: ms is the mass, in grams, of the sample;
m1 is the mass, in grams, of immersion liquid required to fill the empty pycnometer;
m2 is the mass, in grams of immersion liquid added to fill the pycnometer containing the sample;
densityIL is the density of the immersion liquid
Mean Result : Relative density (D20 4) = 1.009
Sample density = 1009 kg.m-3 @ 20°C
Description of key information
relative density: 1.009 at 20 °C (EU A.3, pycnometer method)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.009
Additional information
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.
