- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2013-02-12
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study. Substance ID is adequately specified with isomers composition. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- GLP compliance:
- yes (incl. QA statement)

- Type:
- relative density
- Density:
- 1.04 other: relative density is dimensionless
- Temp.:
- 20.6 °C
- Remarks on result:
- other: D(20/4)
- Conclusions:
- The density is similar to water.
- Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, gas comparison pycnometer method. After triplicate calibration, two independent samples were measured in triplicate, and the mean density at 20°C was calculated to be 1040 kg/m3. This results was then converted to relative density towards water at 4°C.
The density of the test substance at 20°C is 1040 kg/m3, and its relative density D(20/4) is 1.04.
