- Remarks:
- Instead of the UN gap test the BAM Trauzl Test was carried out according to 11.3.5 respectively 12.3.4. of the UN-MTC
- Principles of method if other than guideline:
- A screening OTA (based on DIN 51007) was made in order to rule out a decomposition of the test substance. A sample of the test item in a melted glass container was heated up in a OTA oven with a linear rate of 3 K/min up to 500 °C. A sample of aluminum oxide was heated in the same oven as comparison. The temperature differences of both samples were recorded electronically. From these differences the heat flow of transformation of the test item was calculated electronically. The result was plotted as time/heat-flow diagram. Integration gives the heat release of the transformation. The test was made twice.
The test was performed according to Test Series 1 and 2 of UN-MTC. The test of explosive properties consists of three tests.
UN gap test / BAM Trauzl test
Instead of the UN gap test the BAM Trauzl Test was carried according to 11.3.5 respectively 12.3.4. of the UN-MTC. The test was performed as described in the test procedure F.3 of UN-MTC. The test item was filled in the hole of a massive lead-block and after plugging with sand ignited with a standard detonator Nr. 8. The increase of the hole was assessed by filling with water. The increase was referred to 10 g of substance. The test was performed twice.
Koenen-Test (determining the effect of heating under confinement)
This test is used to determine whether the sample shows an explosive decomposition behavior under the influence of intense heat and under high confinement. The test was performed as described in the test procedure Test 1 (b) respectively Test 2 (b) of UN-MTC.
Time pressure test (determining the effect of ignition under confinement)
The test was performed as described in the test 1 (c) respectively test 2 (c) of UN-MTC. The test was performed 3 times. - GLP compliance:
