Determination of flash point — Pensky-Martens closed cup method

Le présent document décrit trois méthodes 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. Les méthodes sont applicables aux distillats de pétrole (carburant diesel, mélanges de biocarburant, fioul domestique et turbocombustibles) , aux huiles lubrifiantes neuves et en service, aux peintures et vernis, à des liquides homogènes, 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, aux esters méthyliques d''acides gras (EMAG) de type NF EN 14214+A1. Les kérosènes peuvent être soumis à l''essai selon le présent document, cependant, il est d''usage courant de déterminer le point d''éclair des kérosènes selon la NF EN ISO 13736. De façon analogue, les huiles lubrifiantes sont normalement soumises à l''essai suivant la NF EN ISO 2592. Le présent document n''est pas applicable aux peintures et vernis renfermant de l''eau.
