Remarks on result:
other: The sample entered a long shallow endotherm then entered a long shallow exothermic reaction, reaching its self-ignition point at 390°C.
at atm. press. of 1.0 atm
The Auto-flammability temperature of MEA-LAS was 390°C (determined by EU Method A.16).
Executive summary:

Auto-flammability temperature of MEA-LAS was determined by following the EU Method A.16 (Relative Self-Ignition Temperature for Solids).

The relative self ignition temperature test for solids was performed in a temperature programmed oven of approximately 2 L volume with natural air circulation. A stainless steel wire mesh, 20 mm test cube with 0.045 mm openings was filled with the test sample. The cube was then gently tapped and refilled until completely full. The sample temperature was monitored by a thermocouple placed in the centre of the test cube. Another thermocouple was placed between the test cube and the oven wall to monitor oven temperature. The temperature of the oven and the sample are continuously recorded while the temperature of the oven was increased to 400°C or to the melting point of the solid, if lower, at a rate of 0.5°C/min. The temperature of the oven at which the sample temperature reaches 400°C by self heating was called the self-ignition temperature.

The Auto-flammability temperature of MEA-LAS was 390°C.

This auto-flammability test is classified as acceptable, and satisfies the guideline requirements of the EU Method A.16 method.
