Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 07 September 2016 to 09 September 2016
- 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:

- Key result
- Relative self-ignition temperature:

- Executive summary:
The auto-flammability of the test material was investigated in a GLP study conducted in accordance to the standardised guideline EU Method A.16.
A wire mesh cube was filled with the test item and tapped gently. More of the substance was added until the cube was completely full. The cube was then suspended in the centre of the oven at room temperature. One thermocouple was placed at the centre of the cube and the other between the cube and the oven wall to determine the temperature difference of the sample and the oven. The temperature difference of the oven and sample were continuously recorded while the temperature of the oven was increased at a rate of 0.5 °C/min. The self-ignition temperature as obtained by this method is the minimum ambient temperature expressed in °C at which the sample temperature reaches 400 °C under the above conditions. The experiment was repeated three times. The test was carried out at about 98.0 – 98.4 kPa atmospheric pressure.
Under the conditions of the study, the relative self-ignition temperature of the test material was 362 °C.
Reference
Three replicate tests were performed. The average of the measured data was reported.
The relative self-ignition temperature of the test material was determined to be 362 °C.
Description of key information
Under the conditions of the study, the relative self-ignition temperature of the test material was 362 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 362 °C
Additional information
The auto-flammability of the test material was invesigated in a GLP study conducted in accordance to the standardised guideline EU Method A.16. The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
