Results and discussion

Any other information on results incl. tables

Using a linear increase in temperature up to melting point, fully hydrogenated coconut oil showed no self-ignition reaction. At the end of the experiments the test item was liquid.

Applicant's summary and conclusion

Conclusions:
In conclusion, fully hydrogenated coconut oil is considered not to be auto-flammable, according to the criteria described in the guideline.
Executive summary:

The relative self-ignition temperature of fully hydrogenated coconut oil was determined according to EU Method A.16.

The test material was filled in a cube (with wire mesh top) and placed in an oven. The temperature of the oven and the sample were continuously recorded using thermocouples while the temperature of the oven increased to the melting point (40 °C) of the test item at a rate of 0.5 °C/min.

Using a linear increase in temperature up to melting point, fully hydrogenated coconut oil showed no self-ignition reaction. At the end of the experiments the test item was liquid.

In conclusion, fully hydrogenated coconut oil is considered not to be auto-flammable, according to the criteria as described in the guideline.
