24、s 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.A flash point value can indicate the presence of highly volatile material(s) i
25、n 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.Flash point determinations are not appropriate for potentially unstable, decomposable, or explosive materials, unless previously
26、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 decomposition, explosion or other adverse effects.Flash point values are not a constant physic
27、al-chemical property of materials tested. They are a function of the apparatus design, the condition of the apparatus used, and the operational procedure carried out. Flash point can therefore be defined only in terms of a standard test method, and no general valid correlation can be guaranteed betw
28、een results obtained by different test methods or with test apparatus different from that specified.ISO/TR 296621(CEN/TR 151382) gives useful advice on carrying out flash point tests and interpreting results.EN ISO 13736:2013 (E) DIN EN ISO 13736:2013-08 4 CAUTION The use of this International Stand
29、ard can involve hazardous materials and equipment. This International Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this International Standard to establish appropriate safety and health practices and determine the ap
30、plicability of regulatory limitations prior to use.1 ScopeThis International Standard specifies a method for the determination of the manual and automated closed-cup flash point of combustible liquids having flash points between 30,0 C to 75,0 C . However, the precision given for this method is only
31、 valid for flash points in the range 8,5 C to 75,0 C.This International Standard is not applicable to water-borne paints.NOTE 1 Water-borne paints can be tested using ISO 3679.3NOTE 2 See 9.1 for the importance of this test in avoiding loss of volatile materials.NOTE 3 Liquids containing halogenated
32、 compounds can give anomalous results.NOTE 4 The thermometer specified for the manual apparatus limits the upper test temperature to 70,0 C.2 Normative referencesThe following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable for its applica
33、tion. For dated references, only the edition cited applies.

34、materials for paints and varnishes Sampling3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.3.1flash pointlowest temperature of the test portion, corrected to a barometric pressure of 101,3 kPa, at which application of an ignition source causes the
35、vapour of the test portion to ignite and the flame to propagate across the surface of the liquid under the specified conditions of test4 PrincipleThe test portion is placed in the test cup of an Abel apparatus and heated to give a constant temperature increase with continuous stirring. An ignition s
36、ource is directed through an opening in the test cup cover at regular temperature intervals with simultaneous interruption of stirring. The lowest temperature at which application of the ignition source causes the vapours of the test portion to ignite and propagate over the surface of the liquid is
37、recorded as the flash point at the ambient barometric pressure. The temperature is corrected to standard atmospheric pressure using an equation.EN ISO 13736:2013 (E) DIN EN ISO 13736:2013-08 5 5 Chemicals and materials5.1 Cleaning solvent, for the removal of traces of sample from the test cup and co
38、ver.NOTE The choice of solvent depends upon the previous material tested, and the tenacity of the residue. Low volatility aromatic (benzene-free) solvents can be used to remove traces of oil, and mixed solvents can be efficacious for the removal of gum-type deposits.5.2 Coolant, water, ethanediol (e
39、thylene glycol), glycerol or silicone oil (optional), for use in an external cooling bath (6.5) or in the Abel apparatus (see 6.1).5.3 Lubricant (optional), to reduce the formation of ice crystals on the cover and shutter mechanism when carrying out tests at temperatures below 5,0 C (see 7.4.3, Note
40、 1).5.4 Verification liquids, as described in Annex D.5.5 Ignitor and pilot light gas, which may be propane, butane or natural gas (not required if an electric ignitor is used).6 Apparatus6.1 Flash point apparatus, as specified in Annex A.If automated equipment is used, ensure that the test cup and
41、cover assembly conform to the key dimensions specified in A.2 and that the procedure described in Clause 10 is followed. The user shall ensure that all of the manufacturers instructions for adjusting and operating the instrument are followed.In cases of dispute, unless explicitly agreed otherwise, t
42、he manual determination of the flash point, using a flame ignition source, shall be considered the reference test.6.2 Thermometers.6.2.1 Test cup thermometer, conforming to the specification given in Annex C.6.2.2 Heating vessel thermometer, conforming to the specification given in Annex C.NOTE Othe
43、r types of temperature-measuring device can be used, provided that they meet the requirements for accuracy and have the same response as the thermometers specified in Annex C.6.3 Timing device, stopwatch or electronic timer with an accuracy better than 5 %.6.4 Barometer, absolute pressure reading, a
44、ccurate to 0,5 kPa. Barometers pre-corrected to give sea-level readings, such as those used at weather stations and airports, shall not be used.6.5 External cooling bath (optional), for assisting in the cooling of the Abel apparatus and test sample (see 7.4.1 and 7.4.2).6.6 Test cup thermal insulati
45、ng cap (optional), to reduce the formation of ice crystals on the cup and cover assembly during sub-ambient testing.EN ISO 13736:2013 (E) DIN EN ISO 13736:2013-08 6 7 Apparatus preparation7.1 Location of the apparatusSupport the Abel apparatus (6.1) on a level and steady surface in a draught-free po
46、sition.NOTE 1 When draughts cannot be avoided, it is good practice to surround the apparatus with a shield.NOTE 2 When testing materials that produce toxic vapours, the apparatus should be located in a fume hood with an individual control of air flow, adjusted such that vapours can be withdrawn with
47、out causing air currents around the test cup during the test.7.2 Cleaning the test cupWash the test cup with an appropriate solvent (5.1) to remove any traces of gum or residue remaining from a previous test. Dry using a stream of clean air to ensure complete removal of the solvent used.7.3 Apparatu
48、s examinationExamine the test cup, the cover and other parts to ensure that they are free from signs of damage and deposits. If any damage is found, either rectify the problem or, if this is not possible, obtain a replacement. If deposits are found remove them.7.4 Heating/cooling7.4.1 Liquid bathsUse water or, for less than or near 0 C bath temperatures, use a mixture of equal volumes of ethanediol (5.2) and water, or glycerol (5.2) and water, or silicone oil, or other suitable liquids, to completely fill the
