Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Thermal Stability (OECD 113): The test item in closed gold plated stainless steel crucibles showed exothermic effects in the temperature ranges of 100 – 130 °C, 150 – 230 °C, 360 – 430 °C and 430 – >500 °C with an overall decomposition energy of >-2540 J/g.

Explosive Properties UN Class 1: In the DSC-measurement the energy of the exothermic decomposition of the test item Isoamyl nitrite was above the threshold of -500 J/g. Therefore, further tests for explosive properties had to be performed.
In the tests on explosive properties according to UN Transport Regulation, Test series 1 and 2 (Koenen- and Time-Pressure Test), and Test series F (BAM Trauzl Test) the test item showed no explosive properties.
