The individual measurements were obtained with an accurancy of < 0.01 g/cm3. According to the guideline, the density of the test substance is given by the mean value.

The density of the test substance at 20ºC was 0.982 g/cm3 (0.982x103kg/m3). The relative density was 0.982.

Conclusions:
A pycnometer with a volume of 10 ml was used for the determination of the density and relative density of 2-sec-butyphenol. The density of the test substance at 20ºC was 0.982 g/cm3 (0.982 x 10E3 kg/m3). The relative density was 0.982.
Executive summary:

The density and relative density of 2 -sec-butylphenol were determined using the pycnometer method. The study followed OECD Guideline 109 (Density of Liquids and Solids) and EU Method A.3 (Relative Density).A pycnometer with a volume of 10 ml was used. The test was performed in duplicate. The individual measurements were obtained with an accurancy of < 0.01 g/cm3. According to the guideline, the density of the test substance is given by the mean value.

The density of the test substance at 20ºC was 0.982 g/cm3 (0.982 x 10E3 kg/m3). The relative density was 0.982.
