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:
Introduction
The relative self-ignition temperature of Trimethylolethane was determined using a procedure designed to be compatible with Method A.16 Relative Self-Ignition Temperature for Solids of Commission Regulation (EC) No 440/2008 of 30 May 2008.
Method
A wire mesh cube was completely filled with the test item and placed in the centre of a temperature controlled laboratory oven at room temperature. 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 208 °C (which was approximately 10 °C higher than the melting temperature, determined as part of a previous study) 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 data logger. Before and after the test the appearance of the test item was recorded.
Result
On heating the test material no relevant exothermic reaction / self-heating of the sample was observed.
Conclusion
It was concluded that the test item does not to have a relative self-ignition temperature below its melting temperature.
