Minimum Ignition Energy Data by Product

Minimum Ignition Data by Product

Definition: the minimum energy that can ignite a mixture of a specified flammable Material with air or oxygen, measured by a standard procedure.

Depending on the specific application, there are several standard procedures for determining MIE of dust clouds, solvent vapours and gases. The common element in all procedures is that the energy is generated by an electrostatic spark discharge released from a capacitive electrical circuit. The exact circuit components and the arrangement of electrodes between which sparks are generated are the principle differences between the methods. In the following table MIE is quoted for flammable substances mixed with air. A reference is provided to indicate the source of the data. MIE values are provided for guidance only. Please check references for specific measurement conditions. Texene LLC makes no claims for the accuracy of the data and accepts no liability for any use of the data.
