Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
05 March 1993
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Qualifier:
equivalent or similar to guideline
Guideline:

Conclusions:
Self ignition was registered at a temperature of 230°C in a warm storage test in a wire basket.
Executive summary:

Study was conducted according to in-house safety standards, using the DTA.

A small exotherm reaction of the test substance occurs at a temperature of about 160°C, followed the main exothermic reaction at the temperature of 260°C.

Self ignition was registered from a temperature of 260°C. The test substance is considered to have the a potential to auto-ignite.
