- Conclusions:
- The pour point 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 in the range of -9 to -6 ± 3°C (264-267 ± K).
- Executive summary:
The pour point 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 via thermal analysis in a procedure comptabile with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No. 440/2008 (30 May 2008), Method 102 of the OECD Guidelines for Testing of Chemicals (27 July 1995) and Method 830.7200 of the OSCPP Guidelines (March 1998).
In the preliminary and definitive test, a similar process was employed. An aliquot of the test substance was added to the test jar and then placed inside the glass jacket and heated to 46°C and then allowed to cool in the air. At 35°C, the sample was transferred to a -1°C ice/water bath and at 10°C it was transferred to a -18°C ice/acetone bath. At 7°C, the sample was transferred to a -35°C dry ice/acetone bath. Beginning at 46°C in the preliminary test or at -6°C in the definitive test and at 3°C intervals, the sample was tilted to a horizontal position for 5 seconds during which the sample is observed for signs of flow until it is seen to be no longer mobile. At this point, the temperature was recorded and then 3°C were added to this value to obtain the pour point.
Following this technique, the pour point of the test substance was determined to be -9 to -6 ± 3°C.
