1.1 This test method is applicable to determina-tion of minimum temperature of a prescribed hot surface which will result in the ignition of a cloud of dust or other particulate solid. The test is intended to be carried out as a complementary test after determining the minimum ignition temperature of a dust layer by the method specified in Part 1 of this standard.
1.2 The method is not suitable for use with substances having explosive properties. Also, the method is not applicable to dusts which may, over a longer time than provided for in the test method, produce from deposits the gases generat-ed during pyrolysis or smouldering.
