30、s, adhesives, petroleum, and related products. ISO 15161and ISO 15232are also closed cup equilibrium test methods that are to be considered when selecting a method.The apparatus specified in this International Standard enables a similar test result to be determined using a more rapid procedure and a
31、 smaller test portion (2 ml or 4 ml) than that required in ISO 1516 and ISO 1523. In addition, the apparatus can be made portable to the extent of being suitable for on-site testing in addition to its more normal use in laboratories.Collaborative work3has shown that results obtained by these methods
32、 are comparable. The interpretation of flash point results obtained on solvent mixtures containing halogenated hydrocarbons should be considered with caution, as these mixtures can give anomalous results.4A limited study has indicated that some water borne paints can give an elevated flash point whe
33、n an electric ignitor is used with ISO 3679.Flash point can be used in shipping, storage, handling, and safety regulations, as a classification property to define “flammable” and “combustible” materials. Precise definition of the classes is given in each particular regulation.The flash point can ind
34、icate the presence of highly volatile material(s) in a relatively non-volatile or non-flammable material and flash point testing can be a preliminary step to other investigations into the composition of unknown materials.It is not appropriate for flash point determinations to be carried out on poten
35、tially unstable, decomposable, or explosive materials, unless it has been previously established that heating the specified quantity of such materials in contact with the metallic components of the flash point apparatus, within the temperature range required for the method, does not induce decomposi
36、tion, explosion or other adverse effects.The flash point is not a constant physical-chemical property of a material tested. It is a function of the apparatus design, the condition of the apparatus used, and the operational procedure carried out. Flash point can therefore only be defined in terms of
37、a standard test method, and no general valid correlation can be guaranteed between results obtained by different test methods or with test apparatus different from that specified.ISO/TR 296625(an adoption of CEN/TR 151386) gives useful advice in carrying out flash point tests and interpreting result

This International Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user
39、of this International Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1 ScopeThis International Standard specifies procedures for flash point tests, within the temperature range of 30 C to 300 C, for paints, includi
40、ng water-borne paints, varnishes, binders for paints and varnishes, adhesives, solvents, petroleum, and related products. The 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)
41、. When used in conjunction with the flash detector (A.1.6), this International Standard is also suitable to determine the flash point of fatty acid methyl esters (FAME).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensab
