Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

11 October 2018 to 12 October 2018

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Version / remarks:

2008

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Key result

Relative self-ignition temperature:

> 70 °C

Remarks on result:

no self-ignition observed up to the melting point

Three replicate tests were performed. No relative self-ignition temperature of the test material was observed up to the melting of test material (around 70 °C) and is therefore considered not auto-flammable.

Conclusions:

Under the conditions of the study no relative self-ignition temperature of the test material was observed up to the melting of test material (around 70 °C) and is therefore considered not auto-flammable.

Executive summary:

The relative self-ignition temperature of the test material was assessed in accordance with standardised guideline EU Method A.16 and in compliance with GLP.

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 was increased from about 30°C to 400°C (or to above the melting point), at a rate of 0.5 °C/minute. 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.

Under the conditions of the study no relative self-ignition temperature of the test material was observed up to the melting of test material (around 70°C) and is therefore considered not auto-flammable.

Description of key information

Under the conditions of the study no relative self-ignition temperature of the test material was observed up to the melting of test material (around 70°C) and is therefore considered not auto-flammable.

Additional information

The relative self-ignition temperature of the test material was assessed in accordance with standardised guideline EU Method A.16 and in compliance with GLP. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
