Task 4: UN Series 6 testing of non-exploding, large-scale thermites, large-scale mix ID #2. For many years, the properties of thermites have perplexed test laboratories and regulators; one thermite manufacturer published on their website that they had provided a sample of their thermite to a well-known and respected international test laboratory that performed the UN Test N.1 Flammable solids test on the sample, only to have the thermite pass the test criteria; it was the conclusion of the test laboratory that the thermite was non-regulated for transport. Manufacturers, testing laboratories and regulators have been struggling together with the proper characterization and classification of thermites. U.S. DOT PHMSA, taking a very rational but extremely unpopular position, began regulating thermites, since they were being manufactured with the view to producing a pyrotechnic effect, under the same classification system as explosives.
