Mechanical sensitivity (friction)
Six negative assays were recorded: No friction sensitivity was noted with the test item.
Mechanical sensitivity (shock)
Six negative assays were obtained: No shock sensitivity was noted with the test item.

- By DSC (Differential Scanning Calorimetry)
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The exothermic decomposition energy of the test item is less than 500J/g and it has no potential for rapid energy release, therefore the test item is not suspected of having explosive properties
- Executive summary:
The objective of this study was to determine the enthalpies of the test item accompanied by the reaction/phase transition when the test item is heated. At the same time, the exothermic decomposition enthalpies are used to assess the explosive and self reactive properties of the test item.
The exothermic decomposition energy of the test item is less than 500J/g and it has no potential for rapid energy release, therefore the test item is not suspected of having explosive properties.

Description of key information
Based on negative results on its constituents, the reaction mass is considered as non explosive.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
No data is available on the reaction mass of potassium trifluoromethanesulphinate (TFSK) and potassium trifluoroacetate (TFAK).
Experimental data performed according to the EC A14 method are available on each constituent (i.e. TFSK and TFAK). The result was negative for both constituents.
Justification for classification or non-classification
Based on available data of its constituents, the reaction mass is not classified as explosive.
