Direct Yellow 86 is not explosive when tested according to UN-MTC.
Description of key information
On Direct Yellow 86 explosive properties were tested according to UN-MTC procedure (REACH Annex VII, 7.11 and CLP Annex I, 2.1).
The structural formula of the test item contains functional groups quoted in UN-MTC1 (appendix 6, table A 6.1) which may indicate explosive properties.
Appendix 6, point 3 ‘Screening procedures for substances which may have explosive properties’ of UN-MTC refers to the decomposition energy.
A screening DTA (Differential Thermal Analysis 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 DTA oven with a linear rate of 3 K/min up to 500 °C. A sample of aluminiumoxide was heated in the same oven as comparison. The temperature difference of both sample 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.
No. | Mass | Temperature Range | Type of Effect | Energy |
1 | 26.2 mg | 223 °C to > 500 °C | exothermic | More than -830 J/g |
2 | 22.5 mg | 222 °C to > 500 °C | exothermic | More than -750 J/g |
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.
Test Run | Mass | Volume before Test | Volume after Test | Increase of Volume | Increase of Volume / 10 g |
1 | 8.2 g | 62.0 mL | 63.2 mL | 1.2 mL | 1.5 mL |
2 | 7.9 g | 62.0 mL | 65.0 mL | 3.0 mL | 3.8 mL |
Test result: "no"
Koenen-Test
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) of UN-MTC.
Nozzle Diameter | Sample Mass | Reaction Initiation after | Results |
1 mm | 16.0 g | 52 s | No fragments, cartridge unchanged |
1 mm | 16.0 g | 61 s | No fragments, cartridge unchanged |
1 mm | 15.9 g | 64 s | No fragments, cartridge unchanged |
Result: “—“, no effect on heating under confinement with a limiting diameter less than 1 mm.
Time pressure test
The test was performed as described in the test 1 (c) respectively test 2 (c) of UN-MTC. The test was performed 3 times.
Test Run | Sample Mass | Max. Pressure | Time from 690 kPa to 2070 kPa |
1 | 5.0 g | 844 kPa | N / A |
2 | 5.0 g | 906 kPa | N / A |
2 | 5.0 g | 906 kPa | N / A |
Result. “—“, the substance shows no deflagration.
Direct Yellow 86 is not explosive when tested according to UN-MTC.
