1.1 ,These test methods cover procedures for determining whether a material does or does not flash at a specified temperature or for determining the lowest finite temperature at which a material does flash when using a small scale closed-cup apparatus.2 The test methods are applicable to paints, enamels, lacquers, varnishes, and related products having a flash point between 0 and 110°,C (32 and 230°,F) and viscosity lower than 150 St at 25°,C (77°,F).
