- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 24 November 2015 to 11 January 2016
- 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. Restriction apply considering that a potential deformation of the pycnometer may occur when the heated test item is placed on the apparatus. Therefore a checking the apparatus volume after the test is recommended to confirm that the result can be expressed with 4 decimals. Test substance is adequately specified. Therefore validation with slight restrictions applies.

- Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, pycnometer method.
The heated test item sample with the air bubbles removed which was used in the melting/ freezing point test was also used for this test.
Two runs were performed. As the difference between both determinations was below 20 kg/m3, the results were considered as valid, and the mean density at 20.0 °C was calculated. This result was then converted to relative density towards water at 4 °C.
Mean density: 1.555 x 103 kg/m3 at 20.0 ± 0.5 °C
Mean relative density (D20/4): 1.555

The difference between both determinations was below 20 kg/m3. Therefore, no additional determination was performed.
The heated test item sample with the air bubbles removed which was used in the melting/ freezing point test was also used for this test.
Description of key information
The density of the test item has been determined to be 1 555 kg/m3 at 20.0 ± 0.5 °C and a relative density (D20/4) of 1.555.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.555
Additional information
A GLP reliable experimental study, conducted according to a recognized OECD/EC method (pycnometer method), is available. It is considered as a key study. The result is retained as key value.
