Key result
Boiling pt.:
ca. 329 °C
Atm. press.:
100.6 kPa
Remarks on result:
other: ± 1°C
Conclusions:
The boiling point of the test substance, Terpenes and terpenoids, turpentine oil, beta-pinene fraction polymerised, was determined to be 329 ± 1°C (602 ± 1K) at an atmospheric pressure of 100.6 kPa.
Executive summary:

The boiling point of the test substance, Terpenes and terpenoids, turpentine oil, beta-pinene fraction polymerised, was determined via a procedure compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No. 440/2008 of 30 May 2008 and Method 103 of the OECD Guidlines for Testing of Chemicals, 27 July 1995 and Method 830.7220 of the OCSPP Guidelines, August 1996.

The instrument used was a Mettler Toledo DSC822e Differential Scanning Calorimeter (DSC) and its temperature accuracy was checked prior to testing with indium and zinc and found to be within defined tolerances and the instrument was considered acceptable for use. Aliquots of the test substance was placed in pre-pierced crucibles and were subjected to a thermal programme from 25.0 to 450.0 °C at 20.0°C/min. The appearance of the samples (residue) and their weight change were recorded after the test.

Based on the evaluation of data, the boiling point of the test substance was determined to be 329 ± 1 °C (602 ± 1K) at 101.7 kPa.
