Auto flammability

Link to relevant study record(s)

Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

9 May 2001 - 11 May 2001

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

Study conducted in compliance with agreed protocols, with no or minor deviations from the standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and conducted under GLP conditions.

Qualifier:

according to guideline

Guideline:

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

Deviations:

no

GLP compliance:

yes

Key result

Remarks on result:

no self-ignition observed up to the melting point

The temperature vs. time graph can be seen in Figure 1.

Conclusions:

Under the conditions of the test, the test material did not self-ignite prior to melting at approximately 156 °C.

Executive summary:

The relative self-ignition temperature of the test material was determined in a study performed under GLP conditions and in accordance with the standardised guidelines EU method A.16.

The mesh cube was filled with test material by tapping gently and adding more until the cube was full. The cube was then suspended in the centre of the furnace at room temperature and a thermocouple placed in the centre of the cube. Another thermocouple was placed midway between the furnace wall and the cube in order to monitor the furnace temperature. The temperature of the furnace and sample were then continuously recorded while the temperature of the furnace was increased at a rate of 0.5 °C/min to 400 °C.

Under the conditions of the test, the test material did not self-ignite. There was no exothermic reaction below the melting point of the test material at approximately 156 °C.

Description of key information

The test material did not self-ignite, EU Method A.16, Comb 2001.

Additional information

The relative self-ignition temperature of the test material was determined in a study performed under GLP conditions and in accordance with the standardised guidelines EU method A.16. The study was assigned a reliability score of 1, reliable without restrictions, in line with the principles of Klimisch et al. (1997).
