ISO 3680
DETERMINATION OF FLASH/NO FLASH - RAPID EQUILIBRIUM CLOSED CUP METHOD.
ISO 3680:2004 specifies a method for the determination of the ability of paints (including water-borne paints), varnishes, paint binders, adhesives, solvents and petroleum and related products, when maintained at a selected test temperature within the range of - 30 degrees Celsius and 300 degrees Celsius, and under the conditions of test, to yield sufficient flammable vapour at this temperature to cause ignition on the application of a test flame in a standard manner. When used in conjunction with the flash detector (A.1.6), ISO 3680:2004 is also suitable to carry out a flash/no flash test on fatty acid methyl esters (FAME).
