Standard Test Method for Hot Surface Ignition Temperature of Gases on Flat Surface

Importancia y uso:

5.1 The autoignition temperature (AIT) of a gas mixture is the minimum temperature at which a gas mixture spontaneously ignites without an external ignition source. AIT is typically determined at atmospheric pressure, using small test vessels open to the atmosphere where gas is quickly injected into the test vessel and heated for a pre-determined time observing ignition or non-ignition (Test Method E659). AIT is often not directly applicable to real world conditions. Therefore, there is need for a test that determines if a gas or liquefied gas ignites or does not ignite when released onto a hot surface in a more unconstrained environment.
