NF EN ISO 3679

ISO 3679:2004 specifies a method for the determination of the closed cup flash point of paints (including water-borne paints), varnishes, paint binders, adhesives, solvents, petroleum, and related products having closed cup flash points within the range of - 30 degrees Celsius to 300 degrees Celsius. When used in conjunction with the flash detector (A.1.6), ISO 3679:2004 is also suitable for the determination of the flash point of fatty acid methyl esters (FAME).

Le présent document décrit une méthode pour déterminer si les peintures, les vernis, les liants pour peintures, les adhésifs, les solvants, les produits pétroliers et les produits connexes, lorsqu'ils sont maintenus à une température d'équilibre comprise entre -30 °C et 300 °C, émettent suffisamment de vapeurs inflammables pour provoquer l'inflammation en présence d'une flamme présentée de manière normalisée. Sous certaines conditions d'application la présente méthode convient également pour l'essai de point d'éclair de type passe/ne passe pas des esters méthyliques d'acide gras (EMAG).

This document describes three procedures (A, B and C) covering determinations of flash no-flash and flash point. Rapid equilibrium procedures A and B are applicable to flash no-flash and flash point tests of paints, including water-borne paints, varnishes, binders for paints and varnishes, adhesives, solvents, petroleum products including aviation turbine, diesel and kerosene fuels, fatty acid methyl esters and related products over the temperature range –30 °C to 300 °C. The rapid equilibrium procedures are used to determine whether a product will or will not flash at a specified temperature (flash no-flash procedure A) or the flash point of a sample (procedure B). When used in conjunction with the flash detector (A.1.6), this document is also suitable to determine the flash point of fatty acid methyl esters (FAME). The validity of the precision is given in Table 2. Non-equilibrium procedure C is applicable to petroleum products including aviation turbine, diesel and kerosine fuels, and related petroleum products, over the temperature range –20 °C to 300 °C. The non-equilibrium procedure is automated to determine the flash point. Precision has been determined over the range 40 °C to 135 °C. For specifications and regulations, procedures A or B are routinely used (see 10.1.1).
