Thermal stability (DSC)
In DSC run PN14838 the test item showed an exothermic effect in the temperature range of 110 – 330 °C with a decomposition energy of approx. -140 J/g. In DSC run PN14846 two exothermic effects can be observed in the temperature ranges of 100 – 290 °C and 290 – 370 °C with an overall decomposition energy of approx. -280 J/g.
Due to the fact that the DSC signal got noisy starting at a temperature of approx. 380 °C, which may be caused by a pressure rise inside the crucible, two further measurements in closed gold plated stainless steel crucibles were carried out.
In DSC run PN14615 the test item showed two exothermic effects in the temperature ranges of 100 – 350 °C and 360 – 500 °C. Due to the fact that the second exothermic effect was not finished at the maximum test temperature of 500 °C and could not be recorded completely, the overall decomposition energy is greater than -1160 J/g. In DSC run PN14950 three exothermic effects could be observed in the temperature ranges of 100 – 350 °C, 260 – 310 °C and 370 – 500 °C. Due to the fact that the third exothermic effect was not finished at the maximum test temperature of 500 °C and could not be recorded completely, the overall decomposition energy is greater than -430 J/g.

Due
to the decomposition energy being above the threshold of -500 J/g,
explosive properties cannot be excluded and further tests on explosive
properties were carried in study
CSL-17-1663.05.
Explosive Properties UN Class 1
In the DSC-measurements in closed crucibles of study CSL-17-1663.01 the test item showed a decomposition with an overall decomposition energy of greater than -1160 J/g, meaning the decomposition energy is above the threshold of -500 J/g to exclude explosive properties.
Due to the fact that the decomposition energy is above the threshold of -500 J/g the Koenen- and the Time-Pressure-Test had to be performed.
Due to the fact that the decomposition energy is above the threshold of -800 J/g also the Trauzl test had to be performed.

Three tests witha 1.0 mm diameter orifice plate were performed.

Due to the fact that the test series with a 1.0 mm diameter orifice plate showed no explosionthe UN-Transport Regulation Test 1(b) and Test 2(b) deemed to be “-“.

Due to the fact that the test item did not reach a pressure of 2070 kPa,the UN-Transport Regulation Test 1(c) and 2(c) deemed to be “-“.
Explosive Properties; Trauzl Test
Two tests with a test item mass of approx. 3.45 g were carried out. Thevolume of the enlarged cavity is 3.0 mL. Normalization to 10 g of the test item results in an expansion of 8.7 mL per 10 g, therefore theUN-Transport Regulation Test F.3 results to be “No”.Based on the UN Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of Tests and Criteria, the UN Test Series F.3 can be used as screening tests for assessing the ability to propagate a detonation.Based on this the UN-Transport Regulation Test 1(a) and 2(a) (UN gap test) deemed to be “-“.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
