Reference
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
experimental dates: August 06, 2008
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Remarks:
The study was conducted according to an internationally recognized method, and under GLP; however, calibration was not suitable. Test substance is adequately specified. Therefore validation applies with minor restrictions on accuracy.
Qualifier:
according to guideline
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)

Key result
Type:
relative density
Density:
0.875 other: relative density is unitless
Temp.:
20 °C

Measured values : 0.8749 g/cm3 and 0.8749 g/cm3, at 20.0°C

Mean: 0.8749 g/cm3

Relative density: 0.8749

Conclusions:
The substance is much less dense than water.
Executive summary:

The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, oscillating densitimeter method. Two runs were performed, and the mean density at 20.0 °C was calculated. This result was then converted to relative density towards water at 4 °C.

The density of the test item has been determined to be 0.8749 g/cm3 at 20.0°C and the relative density (D20/4) is 0.8749.

Description of key information

The substance is much less dense than water.

Key value for chemical safety assessment

Relative density at 20C:
0.875

Additional information

A reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Despite minor restrictions due to technical inaccuracy, it is considered as a key study. The result is retained as key data.

Note that this parameter may show some variations, due to the UVCB nature of the substance.
