- Executive summary:
EU Method A.2. – The boiling point of the test item was determined using photocell detection. The procedure employed was designed to be compatible with Method A.2. Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008.
Two determinations were carried out. Aliquots of test item (5 – 10 mm) were placed in capillary tubes fused at one end and subjected to a thermal program from 10 K above ambient to 673 K. Heating was at a constant rate of 5K/min. The boiling point was reached when the flow of vapour bubbles reached a frequency of 0.6 Hz. The mean of both determinations is reported as the boiling temperature.
The thermographic data was used to determine the boiling point of the test item as 100.9 °C ± 0.5 °C at 1013 hPa.
Reference
The boiling point is defined as the temperature at which the vapour pressure equals the standard atmospheric pressure.
The mean of at least two measurements is reported as the boiling temperature. If no boiling point could be determined (e.g. decomposition or sublimation of the test item) no main test was performed. The observed effect and the temperature at which it is observed are reported. If the test item did not boil at a temperature ≤ 673 Kelvin the boiling point is reported as > 673 Kelvin.
The determined value of the atmospheric pressure was processed by the apparatus for the determination of the boiling point and a pressure corrected value for the boiling point of the test item is given.
If no clear/distinct boiling point could be observed (e.g. if the test item consisted of several compounds) a boiling range is reported.

* Boiling point: boiling temperature corrected to standard pressure of 1013 hPa.
Following the outcome of the preliminary test, the main test was started at 92 °C with a heating rate of 0.5 K/min.
Conversion of Units (K to °C): t = T-273.15 (t in °C and T in K)
Calculation of boiling point: Using Sidney Young equation, as per EU A.2./OECD 103.
