prBAS EN ISO 2719:2027

This document specifies three procedures, A, B and C, 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, biodiesel and other liquids in the temperature range of 40 °C to 370 °C. NOTE 1        Although, technically, kerosene with a flash point above 40 °C can be tested using this document, it is standard practice to test kerosene according to ISO 13736.[5] Similarly, lubricating oils are normally tested according to ISO 2592.[2] Procedure A is applicable to distillate fuels (diesel, biodiesel blends, heating oil and turbine fuels), new and in-use lubricating oils, paints and varnishes, and other homogeneous liquids not included in the scope of procedures B or C. Procedure B is applicable to residual fuel oils, cutback residuals, used lubricating oils, mixtures of liquids with solids, and liquids that tend to form a surface film under test conditions or are of such kinematic viscosity that they are not uniformly heated under the stirring and heating conditions of procedure A. Procedure C is applicable to fatty acid methyl esters (FAME) as specified in specifications such as EN 14214[11] or ASTM D6751.[13] This document is not applicable to water-borne paints and varnishes. NOTE 2        Water-borne paints and varnishes can be tested using ISO 3679.[3] Liquids containing traces of highly volatile materials can be tested using ISO 1523[1] or ISO 3679.
