Layer Ignition Temperature (LIT)

About Layer Ignition Temperature (LIT)

The LIT test is one of the three core tests for accessing a materials ignition sensitivity, particularly where ‘Avoidance of Ignition Sources’ is the ‘Basis of Safety’ for the operation. The data is required for defining the maximum operating temperature for electrical and non-electrical equipment used in areas where the test material is present.
Avoidance of Ignition Sources as a Basis of Safety, is often used for processes such as charging vessels from sacks, IBC’s or FIBC’s, pneumatic conveying, milling and tabletting operations to name a few. Many materials, that can create a flammable atmosphere, are found to be insensitive to ignition and therefore it is easy, practical and cost affective to ensure an ignition source capable of initiating a reaction is not present.
Related testing for ‘Avoidance of Ignition Sources’ are Minimum Ignition Energy (MIE), Minimum Ignition Temperature (MIT) and Electrostatic testing.
