Results and discussion

Relative self-ignition temperature (solids)

Remarks on result:

other: A sharp rise in the temp of the sample, with a peak at an oven temp of approx. 350 °C, was registered on the temp curve. This indicates self-heating but is not regarded as self-ignition as the temp of the peak was below 400 °C.

Any other information on results incl. tables

The test item was a buff colored powder. Whilst heating the test item, a sharp rise in the temperature of the sample, with a peak at an oven temperature of approximately 350 °C, was registered on the temperature curve (see attached Fig. 1). This indicates self-heating but is not regarded as self-ignition as the temperature of the peak was below 400 °C. On completion of the test, the cube contained a black charred powder.

Applicant's summary and conclusion

Conclusions:

Copper iodide has been determined not to have a relative self-ignition temperature below 400 °C.
