Test Objective

To screen a sample of Laromer BDDA, ca. 95,255% in order to determine the onset temperature and magnitude of any endothermic or exothermic events when ramped to elevated temperatures

The sample was observed to undergo two exothermic events the first one from 186.69°C which had a heat of decomposition of 443.22 J.g-1 and the second commenced from

382.12°C (56.68 J.g-1).

The total heat of decomposition was found to be > 300 J.g-1. Therefore the sample may have self-reactive properties.

The total heat of decomposition was found to be 500 J.g-1. Therefore the sample may have explosive properties.

Further testing was therefore conducted to confirm whether the test item possesses these properties.
