The first endothermic peak in all tests are the melting of the test item. At approximately 422°C the second endothermic event is the boiling of the substance. During the three tests the atmospheric pressure was close (∆p < 1.5 kPa) to the standard pressure of 101.325 kPa, therefore no correction to normal pressure was necessary.
In test 2 a spike at approximately 200°C is visible. This effect was probably caused by a mechanical knock or abrupt vibration, but had no influence on the detection of the second endothermic peak. Therefore, this test was also used for the calculation of the average onset boiling temperature. In the table below the onset data and statistical calculations of the three determinations are summarized.
