Determination of flash point - Pensky-Martens closed cup method (ISO 2719:2016)
Hardcopy , PDF
22-02-2017
This International Standard describes 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 °ðC to 370 °ðC.
CAUTION For certain mixtures no flash point, as defined, is observed; instead a significant enlargement of the test flame (not halo effect) and a change in colour of the test flame from blue to yellowish-orange can occur. Continued heating can result in significant burning of vapours outside the test cup, and can be a potential fire hazard.
NOTE 1Although, technically, kerosenes with a flash point above 40 °ðC can be tested using this International Standard, it is standard practice to test kerosenes according to ISO 13736 [3] . Similarly, lubricating oils are normally tested according to ISO 2592 [4].
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 residua, used lubricating oils, mixtures of liquids with solids, 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 [5] or ASTM D 6751 [6].
This International Standard is not applicable to water-borne paints and varnishes.
NOTE 2Water-borne paints and varnishes can be tested using ISO 3679 [7]. Liquids containing traces of highly volatile materials can be tested using ISO 1523 [8] or ISO 3679.
