- Remarks:
- At test according to UN-Test series 1 (a) an additional booster from 50 g RDX/wax 95/5 was used due to the too small hole for the detonator in the 160 g booster. The result of this test was not relevant for the final result. At test according to UN-Test series 2 (a) two spacer of each 2.5 cm high was used. The overall high was 5 cm as required by the test procedure.

- Interpretation of results:
- GHS criteria not met

- Executive summary:
In a preliminary screening test a DTA was performed resulting in a heat of decomposition of >925 J/g in the temperature range of 238 - >450°C. Based on the observed exothermic decomposition which is higher than the threshold value of 800 J/g further test were perfomed. To this end, the explosive properties of Macrolex Rot B were investigated according to UN Test series 1 and 2 of the Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria (UN-MTC).
The test of explosive properties consists of three tests: UN gap test / BAM Trauzl test, the Koenen-Test (determining the effect of heating under confinement) and the time pressure test (determining the effect of ignition under confinement).
According to UN Test series 1 and 2 Macrolex Rot B propagates detonation but is not sensitive to shock. Conclusively, according to UN-MTC Macrolex Rot B is too insensitive for acceptance into Class 1 and according to CLP the substance is not an explosive (Bayer AG 2018). Thus, the GHS criteria is not met.
Reference
In a screening test a DTA was perfomred in order to determine the decomposition energy (see IUCLD 4.23: self-reactive substances). The test was made twice:
1.) weight: 23.7 mg 238°C to >450°C exothermic type of effect: >910 J/g energy
2.) weight: 25.0 mg 239°C to >450°C exothermic type of effect: >940 J/g energy
1) BAM Trauzl test
Test run | mass | volume before test | volume after test | increase of volume | increase of volume / 10 g |
1 | 3.1 g | 61.4 mL | 64.6 mL | 3.2 mL | 10.3 mL/10 g |
2 | 3.1 g | 62.7 mL | 65.6 mL | 2.9 mL | 9.4 mL/10 g |
The expansion of the lead block is less than 25 cm2 but more than or equal to 10 cm3 per 10 g of sample, Therefore the test result is “low”
1) UN gap test Series 1(a)
Test run | mass | tube after test | plate after test |
1 | 99.8 g | ripped more than half | holed |
2 | 95.8 g | ripped more than half | holed |
The test result is considered as “+” since a hole is punched through the witness plate. Therefore, the substance propagates detonation.
1) UN gap test Series 2 (a)
Test run | mass | tube after test | plate after test |
1 | 106.7 g | not ripped | unchanged |
2 | 105.9 g | not ripped | unchanged |
The test result is considered as “-“ since the tube is neither fragmented completely nor is the witness plate holed. Therefore, the substance is not sensitive to detonative shock.
2) Koenen-Test (determining the effect of heating under confinement)
nozzle diameter | sample mass | reaction initiation after | results |
1 mm | 10.6 g | 48 sec | no fragments, cartridge unchanged |
1 mm | 11.1 g | 46 sec | no fragments, cartridge unchanged |
1 mm | 10.2 g | 45 sec | no fragments, cartridge unchanged |
2 mm | 12.6 g | 29 sec | no fragments, cartridge unchanged |
2 mm | 11.9 g | 48 sec | no fragments, cartridge unchanged |
2 mm | 11.8 g | 48 sec | no fragments, cartridge unchanged |
Result: “— “, no effect on heating under confinement with a limiting diameter less than 1 mm.
3) Time pressure test (determining the effect of ignition under confinement)
test run | sample mass | max. pressure | time from 690 kPa to 2070 kPa |
1 | 3.2 g | 438 kPa | - |
2 | 3.2 g | 531 kPa | - |
2 | 3.2 g | 563 kPa | - |
In all test runs, the pressure was much lower than 2070 kPa. It can be assumed, that also for 5 g of test substance the pressure would be lower than 2070 kPa.
Result: “—“ , the substance shows no deflagration.
