Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- yes
- Remarks:
- The wire mesh had 0.064 mm openings instead of 0.045 mm as stated in the guideline. This is irrelevant for the outcome of the study.
- Principles of method if other than guideline:
- A certain volume of the substance under test is placed in an oven at room temperature; the temperature/time curve relating to conditions in the centre of the sample is recorded while the temperature of the oven is increased to 400 °C, or to the melting point if lower, at a rate of 0,5 °C/min. 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
- GLP compliance:
- no
