Interpretation of Results
The onset temperature of energetic activity is indicated by examining any deviation in the sample heat flow from the baseline, with a downward deviation indicating endothermic
activity and an upward deviation indicating exothermic activity. The peak height or area under the curve indicates the magnitude of the activity.
DSC data for an exothermic event can be used in order to estimate the temperature at which the time to maximum rate is 24 hours (T 024). The following equation is used:
TD24 = 0.7 x T - 46
where:
TD24 = the temperature at which the time to maximum rate is 24 hours (0 C)
T =the exotherm onset temperature from dynamic DSC data (°C)
The equation is based on the following assumptions:
• a detection limit of 10 W.kg-1
• a specific heat capacity of 1 kJ.kg-1.K-1
• an activation energy of 50 kJ.mol-1
lt is imperative that safety factors are used when relating DSC test data to large scale plant. Typical safety factors of up to 100°C are used on the first detected onset temperature,
although this will be very dependent on the scale on which the material is to be handled and stored. lf the material is to be stored or handled at a temperature near its thermal threshold
(including a safety factor), it is recommended that further tests are conducted under low heat loss conditions to more accurately quantify a safe maximum exposure temperature. Using a
slow heating rate in the DSC test produces a much more accurate definition of onset temperature than that obtained at higher heating rates, and may enable a reduction in the
safety factor. However, when data gained at high heating rates (2 K.min-1 or higher) is interpreted, safety factors of up to 100°C are commonly used.
A sample is a candidate for classification as a UN Class 1 explosive substance if the heat of decomposition is > 500 J.g-1 . A sample is a candidate for classification as a UN Class 4,
Division 4.1 self-reactive substance if the heat of decomposition is > 300 J.g-1
Test Results
The sample was observed to undergo an exothermic event from 178.6°C which had a heat of decomposition of 300 J.g-1. This was followed by an endothermic event which commenced from 278.6°C which had a heat of melting of-162.9 J.g-1 . No further significant energetic events were noted up to 500°C.
The sample is not a candidate for classification as a UN Class 1 explosive substance as the heat of decomposition is < 500 J.g-1 .
The sample is a candidate for classification as a UN Class 4, Division 4.1 self-reactive substance as the heat of decomposition is >= 300 J.g-1
