experimental study
Adequacy of study:
key study
Study period:
13 October 2017 to 16 October 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)
Version / remarks:
2008
Deviations:
no

Key result
Remarks on result:
no self-ignition observed up to the melting point
Remarks:
(200 °C)

- Three replicate tests were performed.

- No ignition was observed up to 200 °C.

Conclusions:
Under the conditions of this study, the relative self-ignition temperature of the test material was > 200 °C.
Executive summary:

The purpose of this test was to provide preliminary information on the autoflammability of solid substance at elevated temperatures. The test was performed in accordance with the standardised guideline EU Method A.16, under GLP conditions.

 A specific amount of the test material was placed in a wire-mesh cube into an oven at room temperature; the temperature difference/time curve of the sample of test material was recorded while the temperature of the oven is increased to the melting of test material (about 200 °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 the test material was observed up to 200 °C.

Under the conditions of this study, the test material was not auto-flammable.

Description of key information

Under the conditions of this study, the relative self-ignition temperature of the test material was > 200 °C.

Key value for chemical safety assessment

Additional information

The purpose of this test was to provide preliminary information on the autoflammability of solid substance at elevated temperatures. The test was performed in accordance with the standardised guideline EU Method A.16, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

A specific amount of the test material was placed in a wire-mesh cube into an oven at room temperature; the temperature difference/time curve of the sample of test material was recorded while the temperature of the oven is increased to the melting of test material (about 200 °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 the test material was observed up to 200 °C.

Under the conditions of this study, the test material was not auto-flammable.
