Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
20 July 2018 to 24 October 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.3 (Relative Density)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Remarks:
Date of Inspection: 18 July 2017 to 20 July 2017 Date on Certificate: 28 November 2017
Type of method:
pycnometer method
Dynamic viscosity of test material:
Not reported but it was reported that due to the high viscosity of the test item, it was not feasible to use standard pycnometers. Therefore it was considered that a universal tube with a microscope slide acting as a "lid" would be more appropriate.

Mean density: 935 kg/m3

Relative density: 0.935

Temperature: 20 °C ± 0.5 °C

Due to the high viscosity of the test item, it was not feasible to use standard pycnometers. Therefore, it was considered that a universal tube with a microscope slide acting as a "lid" would be more appropriate.

Conclusions:
The density of the test item has been determined to be 935 kg/m3 at 20.0 ± 0.5 °C; relative density: 0.935.
Executive summary:

The density of the test item has been determined to be 935 kg/m3 at 20.0 ± 0.5 °C; relative density: 0.935, via the pycnometer method, using a procedure designed to be compatible with Method A.3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012.
