Standard Test Method for Minimum Ignition Energy of a Dust Cloud in Air

Importancia y uso:

5.1 This test method provides a procedure for performing laboratory tests to determine the minimum ignition energy of a dust cloud.

Note 1: For gases and vapors, see Test Method E582.

5.2 The data developed by this test method may be used to assess the spark ignitibility of a dust cloud. Additional guidance on the significance of minimum ignition energy is in X1.1.

5.3 The values obtained are specific to the sample tested, the method used and the test equipment used. The values are not to be considered intrinsic material constants.

5.4 The MIE of a dust as determined using this procedure can be compared with the MIE's of reference dusts (using the same procedure) to obtain the relative sensitivity of the dust to spark ignition. An understanding of the relative sensitivity to spark ignition can be used to minimize the probability of explosions due to spark ignition.
