Language in which you want to receive the document.


This International Standard specifies a method to determine if paints, varnishes, paint binders, solvents, petroleum or related products, when maintained at a selected equilibrium temperature and under the conditions of the test, give off sufficient flammable vapour to cause ignition on application of an external source of flame applied in a standard manner.
This International Standard is not applicable to water-borne paints which may, however, be tested using ISO 3680.
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.
