CAS number: -
The exothermic decomposition enthalpy was calculated by
integration of the exothermal peak. At a heating rate of 3 K/min, an
exothermic reaction started at about 315 °C with a heat release of about
175 kJ/kg, which was not completed until 500 °C. Please refer to the
field "Illustration (picture/graph)".
The Differential Thermal Analysis (DTA) measurement was carried out as
stipulated in UN-MTC (Part III, sub-section 188.8.131.52 Thermal stability
and exothermic decomposition energy).
A small amount of the test item (22.6 mg) was weighed into a crucible
made of glass that was sealed afterwards. The temperature difference
between sample and reference (Al2O3) was measured as a function of
temperature and was recorded electronically.
At a heating rate of 3 K/min, an exothermic reaction started at about
315 °C with a heat release of about 175 kJ/kg, which was not completed
until 500 °C. Based on this thermal behaviour it is expected that the
substance is not explosive.
Therefore, it can be concluded by expert judgement that ‘HPP 12879-1
(Katalysator BM 4)' has no explosive properties. Testing according to
UN-MTC test procedure is not necessary.
HPP 12879 -1 has no explosive properties.
There are no chemical groups associated with explosive properties
present in the molecule. Further more based on the thermal behaviour
(heat release about 175 J/g) it is expected that the substance is not
The available data on explosive properties of the test substance
do not meet the criteria for classification according to Regulation (EC)
1272/2008, and are therefore conclusive but not sufficient for
