Determination of flash point — Pensky-Martens closed cup method

Edition date: 2025-11-21
Cancelled
Available languages: English, French
Summary:

ISO 2719:2016 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 °C to 370 °C.

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 1 Although, technically, kerosene with a flash point above 40 °C can be tested using this International Standard, 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 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[11] or ASTM D6751[13].

ISO 2719:2016 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.



ISO 2719:2016 décrit trois méthodes, A, B, et C, pour la détermination du point d'éclair des liquides combustibles, des liquides contenant des matières solides en suspension, des liquides ayant tendance à former un film en surface dans les conditions d'essai, des biocarburants et d'autres liquides, au moyen de l'appareil d'essai Pensky-Martens en vase clos, dans la plage de température entre 40 °C et 370 °C.

ATTENTION ? Pour certains mélanges, aucun point d'éclair, tel que défini, n'est observé; à la place, il peut y avoir un élargissement significatif de la flamme d'essai (pas de phénomène de halo) et un changement de couleur de la flamme passant du bleu à l'orange jaunâtre. Le maintien du chauffage peut faire qu'une quantité significative de vapeurs soit brûlée à l'extérieur du vase d'essai, ce qui peut constituer un danger d'incendie.

NOTE 1 Techniquement les kérosènes ayant un point d'éclair supérieur à 40 °C peuvent être soumis à essai selon la présente Norme internationale. Cependant, il est d'usage courant de déterminer le point d'éclair des kérosènes selon l'ISO 13736[5]. De façon analogue, les huiles lubrifiantes sont normalement soumises à essai suivant l'ISO 2592[2].

La Méthode A est applicable aux distillats de pétrole (carburant diesel, mélanges de biocarburant, fioul domestique et turbocombustibles), aux huiles lubrifiantes neuves et en service, aux peintures et vernis, et à d'autres liquides homogènes ne faisant pas partie du champ d'application des Méthodes B ou C.

La Méthode B est applicable aux combustibles résiduels, aux résidus de bitumes fluidifiés, aux huiles lubrifiantes usagées, aux mélanges de liquides contenant des matières solides, aux liquides ayant tendance à former un film en surface dans les conditions d'essai ou ayant une viscosité cinématique telle qu'ils ne sont pas chauffés de manière uniforme sous agitation et dans les conditions de chauffage de la Méthode A.

La Méthode C est applicable aux esters méthyliques d'acides gras (EMAG) tels que définis dans des spécifications telles que l'EN 14214[11] ou l'ASTM D 6751[13].

La présente Norme internationale n'est pas applicable aux peintures et vernis renfermant de l'eau.

NOTE 2 Le point d'éclair des peintures et vernis renfermant de l'eau peut être déterminé suivant l'ISO 3679[3]. Les liquides contenant des traces de produits hautement volatils peuvent être analysés conformément à l'ISO 1523[1] ou l'ISO 3679.
