Reference
Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
September 2009
Reliability:

Rationale for reliability incl. deficiencies:
guideline study
Remarks:
Study performed according to international guideline. No deficiencies. Performed under internal quality management system.
Qualifier:
according to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Journal of the European Union no. L142, May 31,2008
Deviations:
no
GLP compliance:
no
Key result
Remarks on result:
no self-ignition observed up to the melting point

The sample melts between 353°C and 355°C which is shown by the nearly isothermal part of the sample temperature profile at that point. No exothermal self-heating occurred before melting. Immediately after melting the sample in its liquid state decomposes which is evidenced by a temperature increase. After the test nearly all sample had disappeared. This result means that Potassium chlorate did not show self-heating up to its melting point, and consequently this substance does not have a self-ignition temperature.

 

Conclusions:
3811-04-9, KClO3
Based on results in this report, this substance does not have a self-ignition temperature.
