This International Standard specifies a method to determine the flash point of paints, varnishes, paint binders, solvents, petroleum or related products.

This International Standard is not applicable to water-borne paints which may, however, be tested using IS0 3679 ([5] in the bibliography).

The method is suitable for use over the temperature range -30 °C to 110 °C, depending on the use of different apparatus listed in Table 1.

The interpretation of results obtained from solvent mixtures containing halogenated hydrocarbons should be considered with caution, as these mixtures can give anomalous results.
