Applicant's summary and conclusion
- Conclusions:
- Self-ignition was not observed.
- Executive summary:
The test was conducted to provide preliminary information on the auto-flammability of solid substances at elevated temperatures in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A16.
The relative self-ignition temperature test for solids was performed in a temperature programmed oven of approximately 2 litres volume with natural air circulation. A stainless steel wire mesh, 20 mm test cube with 0.045 mm openings was filled with the test sample. The cube is then gently tapped and refilled until completely full. The sample temperature was monitored by a thermocouple placed in the centre of the test cube. Another thermocouple was placed between the test cube and the oven wall to monitor oven temperature. The temperature of the oven and the sample were continuously recorded while the temperature of the oven was increased to 400°C or to the melting point of the solid, if lower, at a rate of 0.5°C/min. The temperature of the oven at which the sample temperature reaches 400°C by self-heating is called the self-ignition temperature.
Self-ignition was not observed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
