- other: not self-ignitable
Any other information on results incl. tables
Interpretation: The self-ignition temperature of the test item is the minimum ambient temperature expressed in °C at which a certain volume of a substance ignites under defined conditions.
Results: The plots of the oven temperature and sample temperature versus time are shown in the Figure attached. No significant endothermic or exothermic effect of the test item was observed between 20°C and 186°C (i.e. the melting temperature of the test item). It demonstrated that the test item is not self-ignitable. After the experiment, the test item had turned into a black expanded charred residue and was collected in a container that was placed below the cube. It indicated that the test item had been molten, decomposed and/or reacted during the experiment.
Conclusion: The self-ignition temperature of Tricine was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device. Based on the results obtained the test item is considered ‘not self-ignitable’.
