Observations:

On completion of testing for Basket 1, a crusty, black material remained filling 1/2 of the basket with large quantities on the oven floor. For Basket 2 a brown powder filling approximately 3/4 of the basket remained and for Basket 3 a brown powder filling approximately 4/5 of the basket remained.

Applicant's summary and conclusion

Conclusions:
The test material requires classified as a self-heating substance; however, classification can be exempted if the material is to be transported in volume of no more than three cubic metres.
Executive summary:

The self-hearing properties of the test material were investigated in a study which was conducted under GLP conditions and in accordance with the standardised guideline UN Method N.4.

Findings from the study reveal that the test material requires classified as a self-heating substance of UN Class 4, Division 4.2; however, classification can be exempted if the material is to be transported in volume of no more than three cubic metres.
