Specific details on test material used for the study:

Adiabatic storage test
The test method "adiabatic storage test" determines the rate of heat generation produced by a reacting substance as a function of temperature. The heat generation parameters obtained and the heat loss data relating to a package are used to determine the Self Accelerating Decomposition Temperature (SADT) of a substance in its packaging. The method is appropriate for every type of packaging, including IBCs and tanks.
The test is performed following the procedure of test H.2 of the UN Manual on Tests and Criteria. The apparatus consists of a glass Dewar vessel (0.2 liter) which contains the sample, an insulated aluminium block oven with a differential control system to keep the temperature in the oven within
0.1 oc of the sample temperature and an inert lid for the Dewar vessel. To improve the thermal isolation of the sample the Dewar vessel is set into an autoclave (0 .75 liter; 500 barg) which is afterwards tightly closed. Thermo couples are located in the center of the sample and in the jacket of
the autoclave. A pressure transducer measures the pressure inside the autoclave. The autoclave is homogenuously heated by the aluminum block oven. Heat losses due to condensation of volatile compounds can therefore be excluded. Under such conditions the decomposition process can be
tracked under nearly adiabatic conditions once the starting temperature is reached.

Results and discussion

Results:

UN Transport Regulations: The test item does not have to be classified as "self-reactive substance" (class 4.1) due to the SADT >75 °C.
EU-GHS/CLP: The test item does not have to be classified as "self-reactive substance" due to the SADT >75 °C.
