- Executive summary:
A study was performed to determine explosive property of test substance according to EU Method A.3 in compliance with GLP.
The screening test for explosive properties was performed by DSC, Mettler-Toledo TA8000, closed glass pan, heating rate 3 K/min. Two measurements were performed with both show an exothermic decomposition of the test substance in the range 100-340 °C, with an energies of 691 J/g respectively 636 J/g. The decomposition energies are above 500 J/g, so the main test on explosive properties was performed. The method comprises three parts:
a) a test of thermal sensitivity;
b) a test of mechanical sensitivity with respect to shock;
c) a test of mechanical sensitivity with respect to friction.
The test substance did not show any reaction in above tests.
Under the test conditions, test substance has no danger of explosion
