Burning Test Type MP 1 This test is designed to determine the ignitability and the combustibility of a dried solid according to the following criteria: Can the product be ignited at all? Does the flame propagate? Is there a fire or flameless reaction? What is the propagation velocity of the deflagration? The tests are carried out at room temperature and at elevated temperature (e.g. 100 C). An electrically heated platinum wire is shortly dipped into the test substance and the reaction of the compound is observed.

Test for Exothermic Reaction in an Open Cup - Lutolf Oven Type MP 4 This test is designed to determine the lowest temperature at which a substance shows an exothermic reaction under defined oxygen-lean conditions. It is applied to products, which are exposed to an elevated temperature over long periods, closed off from fresh air (e.g. in vacuum ovens, fluid-bed drier etc.). With this test, the maximum permissible process temperature can be derived. The substances to be tested and a reference substance are heated up at a constant rate of 2.4 C/min. (dynamic test). The temperatures of the samples are recorded. An exothermic reaction is considered to have occurred if the temperature curve of the test sample rises above the reference sample temperature. Alternatively, isoperibolic tests can be carried out, in which the test substance is kept at a constant temperature over a defined period of time. According VDI 2263: Dust fires and dust explosions; hazards, assessment, protective measures; test methods for the determination of the safety characteristic of dusts.

Test for Exothermic Reaction in an Air Stream: Grewer Oven This test is designed to determine the relative auto ignition temperature of a product in a hot air-steam. It is applied to products, which are to be processed at elevated temperatures in the presence of air (e.g. spay drier, circulating air tray drier etc). With this test, the maximum safe process temperature can be derived. The auto ignition of the product tested occurs by reaction with the oxygen in the air and/or by exothermic decomposition. The same test may be done in a nitrogen-stream instead of an air-stream. If both results are compared, the influence of oxygen can be identified.
