DIN EN ISO 9038:2013-12

A product with a flash point within a given range can continue to burn after initial ignition, while a similar product, although it has a similar flash point, may not. This International Standard describes a method for discriminating between those products that sustain combustion and those that do not. The method determines whether a flammable product, when maintained at a selected test temperature, gives off sufficient flammable vapour to cause ignition when an ignition source is applied, and continues to generate sufficient vapour to burn when the ignition source is removed. This test method does not determine the flash point of the product under test but, by means of a pass/fail procedure, merely determines if it sustains combustion (fail) at a selected test temperature, as can be required to comply with laws or regulations relating to the storage, transport and use of flammable products. Before performing the test, it is necessary to determine either the actual flash point of the material or the temperature range in which the flash point is located. The apparatus specified in this International Standard enables a result to be determined by a rapid procedure using a small test portion (2 ml). The committee responsible for this standard is NA 002-00-07 AA "Allgemeine Prüfverfahren für Beschichtungsstoffe und Beschichtungen" ("General test methods for coating materials and coatings") at DIN.
