Applicant's summary and conclusion

Executive summary:

The pure product melted at 100°C and flow completely out of the wire basket. The product mixture with Kieselguhr (1:1) indicates a self ignition starting at 140°C.

The substance has neither to be classified as self heating substance div. 4.2 according to the UN-Transport regulation nor as self heating substance according to GHS.

The test item has no self-ignition temperature according to EC 440/2008, Annex V, part A, A.16 up to the melting of the test item or the maximum temperature of 400°C respectively.
