1.1 This standard ( Part 1 ) is applicable to the determination of the minimum temperature of a prescribed hot surface which will result in the ignition of a layer of dust deposited on it in a specified thickness. The method given here is particularly relevant to industrial equipment with which dusts are present on hot surfaces as thin layers exposed to the atmosphere.
1.2 The method is not suitable for use with sub-stances having explosive properties ( see 0.3 ).
