Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.3 (Relative Density)
Deviations:
no
Principles of method if other than guideline:
Since the test item is a hygroscopic solid and soluble in all established solvents, the displacement method by use of a pycnometer could not be applied. For this reason the test item was filled in a glass vial and weighed. The volume of vial was determined before and the density of the test item could be calculated with the quotient of sample weight and the corresponding volume.
The determined density has to be regarded as an approximate value.
GLP compliance:
yes
Type of method:
other: Relative density by displacement method
Specific details on test material used for the study:
Date of receipt: 2017-04-19
Expiry date: 2018-09-14
Type:
relative density
Density:
0.726
Temp.:
20.4 °C
Remarks on result:
other: mean value of two determinations

The determined density has to be regarded as an approximate value.

Conclusions:
With the test item RFR 6634 the relative density at 20 °C was determined to be 0.726 (mean value of two determinations).
Executive summary:

With the test item RFR 6634 the relative density at 20 °C was determined to be 0.726 (mean value of two determinations).

Since the test item is a hygroscopic solid and soluble in all established solvents, the displacement method by use of a pycnometer could not be applied. For this reason the test item was filled in a glass vial and weighed. The volume of vial was determined before and the density of the test item could be calculated with the quotient of sample weight and the corresponding volume.

Description of key information

With the test item 5-Azoniaspiro[4.5]decane, hydrogen difluoride the relative density at 20 °C was determined to be 0.726 (mean value of two determinations).
