Reference
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
19/03/2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
The study was conducted according to an internationally recognised method and under GLP. Test substance is adequately characterised but restrictions apply considering that details on calibration were lacking and only one determination was performed. However the value is compliant with recognised ISO standard and therefore validation with restriction applies.

Deviations:
no
Qualifier:

RESULTS

Determination 1

Relative density : D2020 = 0,8760 ± 0,0010

Conclusions:
The test substance is less dense than water.
The mean relative density of the test item was D20/20 = 0,8760 ± 0,0010.
Executive summary:

The density of the test substance was measured according to OECD 109 / EU A3 guideline, using oscillating density meter.

The relative density of the test item was measured as D20/20= 0,8760 ± 0,0010.

Description of key information

The relative density of the test item was measured as D20/20= 0,8760 ± 0,0010.

The substance is less dense than water.

Key value for chemical safety assessment

Relative density at 20C:
0.876

Additional information

A fully reliable experimental study, conducted according to OECD 109 /EU A3 guideline, using oscillating density meter, is available. It is considered as a key study, and the result is retained as key data.
