Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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)

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.
