Specifies methods for combustible liquids, liquids with suspended solids, lubricating oils, liquids that tend to form a surface film under the test conditions, and other liquids.
Le but de la présente norme est de décrire une méthode de détermination du point d'éclair en vase clos, des produits et mélanges pétroliers dont le point d'éclair est supérieur à 50 °C, à l'exception des bitumes fluxés.
ISO 2719:2002 describes two procedures, A and B, using the Pensky-Martens closed cup tester, for determining the flash point of combustible liquids, liquids with suspended solids, liquids that tend to form a surface film under the test conditions and other liquids. It is applicable for liquids with a flash point above 40 degrees C. Procedure A is used for the determination of the flash point of paints and varnishes that do not form a surface film, unused lubricating oils and other petroleum products not covered by Procedure B. Procedure B is used for the determination of the flash point of residual fuel oils, cutback bitumens, used lubricating oils, liquids that tend to form a surface film, liquids with suspensions of solids and highly viscous materials such as polymeric solutions and adhesives. ISO 2719:2002 is not applicable to water-borne paints or liquids contaminated by traces of highly volatile materials.
