- Conclusions:
- The density of the test substance, Terpenes and terpenoids, turpentine oil, beta-pinene fraction polymerised, was determined via the pycnometer method to be 951 kg/m^3 at 20.0 ± 0.5°C and the relative density was determined to be 0.951.
- Executive summary:
The density of the test substance, Terpenes and terpenoids, turpentine oil, beta-pinene fraction polymerised, was determined via the pycnometer method in a procedure compatible with Method A.3 Relative Density of Commission Regulation (EC) No. 440/2008 of 30 May 2008 and 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 the purified water and the test substance were equilibrated at 20.0 ± 0.5°C. The glass pycnometer was cleaned and dried to constant weight and then filled with the equilibrated purified water and re-weighed. The pycnometer was emptied and dried again and subsequently filled with the equilibrated test substance and re-weighed. The procedure was performed in duplicate.
The density of the test substance was then calculated via the following equation: ρ= [d(c-a)/(b-a), where a = mass of pycnometer (g), b = mass of pycnometer filled with water (g), c = mass of pycnometer filled with test substance (g), d = density of water at test temperature (kg/m^3). The relative density was also determined, via the following equation: D204 =ρ/(999.97 kg/m^3)
The density of the test substance was determined to be 951 kg/m^3 at 20.0 ± 0.5°C and the relative density was determined to be 0.951.
