Applicant's summary and conclusion

Conclusions:
The test material has been determined not to have a relative self-ignition temperature below its melting temperature.
Executive summary:

Method

The test material was heated in an oven and the relative self ignition temperature determined. Testing was conducted using Method A16 Relative Self-Ignition Temperature for Solids of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Procedure

An aliquot of the test material was suspended in a stainless steel mesh cube (approximately 20 x 20 x 20 mm) in an oven. A thermocouple was placed in the centre of the sample and another in the oven. The oven temperature was programmed to increase from ambient to 186°C (which was approximately 10°C higher than the melting temperature, determined as part of Harlan Laboratories Ltd project number 0102/0658) at a rate of 0.5°C/min. The temperature/time curves relating to the condition in the centre of the sample and the oven were recorded on a two channel chart recorder.

Conclusion

The test material has been determined not to have a relative self-ignition temperature below its melting temperature.
