Conclusions:

The density of the test substance, Terpenes and Terpenoids, turpentine-oil, limonene fraction, polymers with 1-methyl-4-(1-methylethenyl)cyclohexane and turpentine-oil β-pinene fraction terpenes, was determined to be 967 kg/m^3 at 20.0 ± 0.5°C with a relative density of 0.967.

Executive summary:

The density and relative density of the test substance, Terpenes and Terpenoids, turpentine-oil, limonene fraction, polymers with 1 -methyl-1 -4 -(1 -methylethenyl)cyclohexane and turpentine-oil β-pinene fraction terpenes, was determined via the pycnometer method in a process compatible with Method A.3 Relative Density of Commission Regulation (EC) No. 440/2008 (30 May 2008), Method 109 of the OECD Guidelines for Testing of Chemicals (02 October 2012) and Method 830.7300 of the OCSPP Guidelines (June 2002).

Separate aliquots of purified water and the test substance were equilibrated at 20.0 ± 0.5°C. A glass pycnometer apparatus was used . The pycnometer was cleaned and dried to constant weight and then filled with the equilibrated water and re-weighed. The apparatus was emptied and dried and then filled with the equilibrated test substance and re-weighed. The procedure was performed in duplicate. The density of the test substance was determined using 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 then calculated: (D₄²⁰) = ρ / (999.97 kg/m^3).

Following this method, the density of the test substance was determined to 967 kg/m^3 at 20.0 ± 0.5°C with a relative density of 0.967.
