Purpose
The purpose of the Minimum Ignition Temperature of dust clouds (MITdc) test is to determine the minimum temperature of a hot surface able to ignite a dust cloud.
The MITdc is used In combination with the Minimum Ignition Energy (MIE) of dust clouds to assess the hazards of ignition by mechanical sparks.
Method
We perform this test in accordance with EN 80079-20-2 “Explosive atmospheres – Part 20-2: Material Characteristics – Combustible dust test methods“.
We disperse dust samples of various sizes into the Godbert-Greenwald Furnace and vary the temperature of the furnace walls until the lowest temperature of the wall at which the dust cloud still ignites is found.
Benefit
The determination of the MITdc helps you understand the ignition sensitivity of your product when it forms a dust cloud.
The result is relevant for defining the maximum operating temperature for electrical equipment (together with the minimum ignition temperature of a dust layer (MITdl)), i.e. choice of electrical equipment and set values for monitoring temperatures of rotating equipment used in dusty environments.
