Any other information on results incl. tables

Results

Whilst heating the test item,no relevant exothermic reaction was observed.The temperature/time curve is shown in Attachment 2. On completion of the test, the cube was empty, a brown liquid was observed beneath the cube.

Applicant's summary and conclusion

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

Principle of the Test

The test item is heated in a fine mesh stainless steel cube that is suspended in an oven. The temperature/time-curves of both test item and oven are recorded.

           

Performance of the Test

The cube was completely filled with the test item and placed the center of the 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 to178°C (which was approximately 10°C higher than the melting temperatures supplied by the Sponsor) 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. Before and after the test the appearance of the test item was recorded.

         

Conclusion

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