The density of water was determined to be 999.97 kg/m^3 at 4°C.

Conclusions:

The density of the test item Terpenes and terpenoids, terpentine oil, alpha-pinene fraction, dimers was determined to be 951 kg/m^3 at 20.0 ± 0.5 °C with a relative density of 0.951 at a temperature of 20.0 ± 0.5°C.

Executive summary:

The density of the test substance, Terpenes and terpenoids, terpentine oil, alpha-pinene fraction, dimers, was determined using the pycnometer method in a process compatible with Method A.3 Relative Density of Commission Regulation (EC) No. 440/2008 of 30 May 2008, Method 109 of the OECD Guidelines for Testing of Chemicals 02 October 2012 and Method 830.7300 of the OSCPP Guidelines, June 2002.

Separate aliquots of purified water and test material were equilibrated at 20°C ± 0.5°C. The pycnometer was empited and dried to constant weight and then filled with the equilibrated water and re-weighed. The pycnometer was empited and dried and then filled with the equilibrated test item and re-weighed. The procedure was performed in duplicate.

The density of the test item was calculated using an equation based on the ratio of the mass of test item to the mass of water used to fill the pycnometer and determined to be 951 kg/m^3, The relative density was determined to 0.951.
