This European Standard specifies a method of test to determineThe minimum ignition energy of a dust/air mixture by an electricallygenerated spark.The test method is not suitable for use with recognised explosives, gunpowder, dynamite, explosives which do not require oxygen for combustion; pyrophoric substances, or substances or mixtures of substances which can under some circumstances behave in a similar manner. Where any doubt exists aboutThe existence of a hazard due to explosive properties, expert advice should be sought.
