Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Table 1 shows the determined volume of the pycnometer. The results of the test for the determination of the density of the test item are given in Table 2.

The individual measurements were obtained with a deviation of ≤ 0.01 g/cm3. According to the guideline, the density of the test item is given as the mean value.

Conclusions:
The density of the test item at 20ºC was 1.17 g/cm3 (1170 kg/m3).
The relative density was 1.17.
Executive summary:

A pycnometer was used for the determination of the density and relative density of the test item.

The density of the test item at 20ºC was 1.17 g/cm3 (1.17 x 103 kg/m3).

The relative density was 1.17.
