Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

1 August 2012 to 23 August 2012

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)

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Key result

Relative self-ignition temperature:

262 °C

Remarks on result:

other: No data on pressure reported. Determination assumed to be performed at normal atmospheric pressure.

The test material was a white solid. Whilst heating the test material, self-heating of the sample was observed. On completion of the test, the test material was a fused white solid.

Conclusions:

The test material was determined to have a relative self-ignition temperature of 262 °C.

Executive summary:

The relative self-ignition temperature of the test material was investigated in a GLP study which was conducted in accordance with the standardised guideline EU Method A.16. During the study a wire mesh cube was completely filled with the test material and placed in the centre of an oven at room temperature. A thermocouple was placed in the centre of the sample and another in the oven. The oven temperature was increased from ambient to 400 °C at a rate of 0.5 °C/min. The test material was a white solid. Whilst heating the test material, self-heating of the sample was observed. On completion of the test, the test material was a fused white solid. The test material was determined to have a relative self-ignition temperature of 262 °C.

Description of key information

Self-heating of the substance was observed during the test, the relative self-ignition temperature was determined to be 262 °C

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

262 °C

Additional information

The relative self-ignition temperature of the test material was investigated in a GLP study which was conducted in accordance with the standardised guideline EU Method A.16. The study was assigned a reliability score of 1 in accordance with the principles for assessing data quality as detailed by Klimisch et al (1997).

During the study a wire mesh cube was completely filled with the test material and placed in the centre of an oven at room temperature.
