Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 11 February 1999 to 16 April 1999
- 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:
- not specified
- GLP compliance:
- yes
- Key result
- Remarks on result:
- no self-ignition observed up to the melting point
- Conclusions:
- Under the conditions of the study, there was no self-ignition temperature prior to melting at 90 to 100 °C.
- Executive summary:
The autoflammability of the test material was assessed according to EU Method A.16 and in compliance with GLP.
A mesh cube was filled with test material 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.
There was no exothermic reaction of the test material below its melting point at approximately 90 to 100 °C.
Under the conditions of the study, there was no self-ignition temperature prior to melting at 90 to 100 °C.

- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- Under the conditions of the study no self-heating was observed.
- Executive summary:
The autoflammability of the test material was assessed according to EU Method A.16 and in compliance with GLP
A certain volume of the test material under test is placed in an oven at room temperature; the temperature/time curve is recorded while the temperature of the oven is increased to 400 °C at a rate of 0.5 ºC/min.
Under test conditions no self-heating was observed. At the end of the test the wire basket was empty.
Under the conditions of the study no self-heating was observed.
