scope:

This International Standard specifies a pass/fail procedure, at temperatures up to 100 °C, to determine whether or not a liquid product, that would be classified as "flammable" by virtue of its flash point, has the ability to sustain combustion at the temperature or temperatures specified in the appropriate regulations. NOTE 1 Many national and international regulations classify liquids as presenting a flammable hazard on the basis of their flash point, as determined by a reconized method. Some of these regulations allow a derogation if the substance cannot "sustain combustion" at some specified temperature or temperatures. NOTE 2: In connection with the United Nations recommendations on the Transport of Dangerous Goods as well as with the Globally Harmonized System of Classification and Labelling of Chemicals, and also with derived national/EC regulations, temperatures of 60,5 °C and 75,0 °C are specified for this test [1][2] The procedure is applicable to paints (including water-borne paints), varnishes, paint binders, solvents, petroleum or related products and adhesives, which have a flash point. It is not applicable to painted surfaces in respect of assessing their potential fire hazards. NOTE 3 This test method can be used, in addition to test methods for flash point, in assessing the fire hazard of a product. Particular care needs to be taken in translating results from small scale tests to large scale (real life) situations, as liquids in large quantities may not behave in the same way as small samples because geometry and the surface to volume ratio affect rates of heat transfer and evaporation from the surface
