Reference
Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
15 November 2017 to 17 November 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Key result
Relative self-ignition temperature:
> 400 °C
Remarks on result:
no self ignition observed under the test conditions
Conclusions:
Three replicate tests were performed. No relative self-ignition temperature of Cadmium selenide was observed up to 400°C.
Executive summary:

The purpose of this test was to provide preliminary information on the auto-flammability of solid substance at elevated temperatures. A specific amount of the test substance was placed in a wire-mesh cube into an oven at room temperature; the temperature difference/time curve of the sample of test item was recorded while the temperature of the oven is increased to 400°C at a rate of 0.5°C/min. For the purpose of this test, the temperature of the oven at which the sample temperature reaches 400°C by self-heating is called the self-ignition temperature.

Three replicate tests were performed. No relative self-ignition temperature of Cadmium selenide was observed up to 400°C.

The test item was not auto-flammable under the conditions of the test.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
400 °C
