Trauzl-Test
The results are summarized in the Table below:
No. | Mass | Volume Before test | Volume After test | Increase of Volume | |
1 | 14.2 g | 60.9 mL | 78.6 mL | 17.7 mL | 12.5 mL / 10 g |
2 | 13.9 g | 60.4 mL | 80.3 mL | 19.9 mL | 14.3 mL / 10 g |
Test result: low
Since the determined volume increase per 10 g test item is ≥ 10 mL and < 25 mL, the result is “low”. The UN gap test according to UN-MTC procedure was necessary.
UN Gap Test
The results are summarized in the Table below:
No. | Sample nr. | Mass | Steel tube after Test | Witness Plate after Test |
1 | 132046 | 771.0 g | not fragmented | not holed or punched |
2 | 132196 | 760.2 g | not fragmented | not holed or punched |
Test result: negative
Koenen test
The Koenen test was started with a diameter of 5 mm and subsequently continued with 3 mm, 2 mm, 1.5 mm and 1 mm. The physical state of the test item (solid) excludes the enrichment of high-energy components caused by evaporation of volatile solvents. Therefore, an explosion with larger nozzles could be excluded. 7 tests were performed. Tests were performed with a circular nozzle plate with a hole of varying diameters.The results are shown in Table below.
No. | Orifice Diameter | Mass | Reaction Initiation after | Results |
1 | 1 mm | 39.3 g | 69 s | no fragments, cartridge unchanged |
2 | 1 mm | 39.3 g | 66 s | no fragments, cartridge unchanged |
3 | 1 mm | 39.3 g | 69 s | no fragments, cartridge unchanged |
4 | 2 mm | 39.3 g | 72 s | no fragments, cartridge unchanged |
5 | 2 mm | 39.3 g | 67 s | no fragments, cartridge unchanged |
6 | 2 mm | 39.3 g | 69 s | no fragments, cartridge unchanged |
Result: “ — “, no effect on heating under confinement with a limiting diameter less than 1 mm.
Time / pressure test
Table below shows the used amounts of sample and the results from the Time / pressure test.
No. | Mass | Max. Pressure | Time from 690 kPa to 2070 kPa |
1 | 5.0 g | 1438 kPa | N/A (2070 kPa was not reached) |
2 | 5.0 g | 1125 kPa | N/A (2070 kPa was not reached) |
3 | 5.0 g | 1188 kPa | N/A (2070 kPa was not reached) |
Result: “ ̶ “, the substance shows no deflagration.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- due to 'low' results from the BAM Trauzl test, and negative results from UN tests 1(b) (effect of heating under confinement) and 1 (c) (effect of ignition under confinement), and UN tests 2(a) (UN Gap test), the test item can be excluded from classification in class 1 (explosives) according to series 1 and 2 of the UN Manual of Tests and Criteria, revision 7 (2019).
