Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Temp.:
21 °C
Remarks on result:
other: temperature was 21±0.5⁰ C
Conclusions:
Under the study conditions, the relative density of the test substance was determined to be 3.1 at 21.0 ± 0.5°C.
Executive summary:

A study was conducted to determine the relative density of the test substance according to EU Method A.3 and OECD Guideline 109, in compliance with GLP. The relative density was determined at 21±0.5°C using air comparison pycnometer. Under the study conditions the relative density of the test substance was determined to be 3.1 at 21.0 ± 0.5°C (Fox, 2009)

Density:
>= 1.05 - <= 2.4 g/cm³
Temp.:
15.6 °C
Remarks on result:
other: The density range for the 60-84% test substance composition is 1.7 to 2.3 g/cm3.
Conclusions:
Under the study conditions the relative density of the test substance was established to be within the range of 1.05-2.40 g/cm3 at 15.6°C.
Executive summary:

A study was conducted to determine the relative density of the test substance using a method from the Technical Manual, part A: chemical and physical properties, section A2: brine density and PVT data. Under the study conditions the relative density of the test substance was established to be within the range of 1.05-2.40 g/cm3 at 15.6°C (Company data, 2008).

Description of key information

Solid form: the relative density was determined according to EU Method A.3 and OECD Guideline 109.

Brine: the relative density was established using a method from the Technical manual, Part A: chemical and physical properties, section A2: brine density and PVT data.

Key value for chemical safety assessment

Additional information

Solid form: 3.1 at 21.0 ± 0.5°C

Brine: 1.05-2.40 g/cm3 at 15.6°C
