Key result
Remarks on result:
no self-ignition observed up to the melting point
Conclusions:
In the course of this study the test item 2,4,8,10-Tetraoxa-3,9-dithiaspiro[5.5]undecane, 3,3,9,9- tetraoxide did not self-ignite up to the melting point (276.9 °C, based on Safety Data Sheet, provided by the Sponsor). Thus, no self-ignition temperature could be stated.
Executive summary:

In the course of this study the test item 2,4,8,10-Tetraoxa-3,9-dithiaspiro[5.5]undecane, 3,3,9,9- tetraoxide did not self-ignite up to the melting point (276.9 °C, based on Safety Data Sheet, provided by the Sponsor). Thus, no self-ignition temperature could be stated.
