ForewordDIN EN ISO 9038:2013-12EN ISO 9038:2013 (E)3IntroductionA product with a flash point within a given range can continue to burn after initial ignition, while a similar product, although it has a similar flash point, may not.

23、 This International Standard describes a method for discriminating between those products that sustain combustion and those that do not.The method determines whether a flammable product, when maintained at a selected test temperature, gives off sufficient flammable vapour to cause ignition when an i

24、gnition source is applied, and continues to generate sufficient vapour to burn when the ignition source is removed.This test method does not determine the flash point of the product under test but, by means of a pass/fail procedure, merely determines if it sustains combustion (fail) at a selected te

25、st temperature, as can be required to comply with laws or regulations relating to the storage, transport and use of flammable products. Before performing this test, it will normally be necessary to determine either the actual flash point of the material or the temperature range in which the flash po

26、int is located.The apparatus specified in this International Standard enables a result to be determined by a rapid procedure using a small test portion (2 ml).4DIN EN ISO 9038:2013-12EN ISO 9038:2013 (E) WARNING The use of this International Standard may involve hazardous materials, operations or eq

27、uipment. 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 to determine the applicability of regulatory limitations p

28、rior to use.1 ScopeThis International Standard specifies a pass/fail procedure, at temperatures up to 100 C, to determine whether or not a liquid product, that would be classified as “flammable” by virtue of its flash point, has the ability to sustain combustion at the temperature or temperatures sp

29、ecified in the appropriate regulations.NOTE 1 Many national and international regulations classify liquids as presenting a flammable hazard on the basis of their flash point, as determined by a recognized method. Some of these regulations allow a derogation if the substance cannot “sustain combustio

30、n” at some specified temperature or temperatures.NOTE 2 In connection with the United Nations recommendations on the Transport of Dangerous Goods as well as with the Globally Harmonized System of Classification and Labelling of Chemicals, and also with derived national/EC regulations, temperatures o

31、f 60,5 C and 75,0 C are specified for this test.12The procedure is applicable to paints (including water-borne paints), varnishes, paint binders, solvents, petroleum or related products and adhesives, which have a flash point. It is not applicable to painted surfaces in respect of assessing their po

32、tential fire hazards.NOTE 3 This test method can be used, in addition to test methods for flash point, in assessing the fire hazard of a product.NOTE 4 Particular care needs to be taken in translating results from this test method to large scale (real life) situations, as liquids in large quantities

33、 may not behave in the same way as small samples.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、lication of an ignition source causes the vapour of the test portion to ignite momentarily and the flame to propagate across the surface of the liquid, under the specified conditions of test4 PrincipleA test portion of specified volume is introduced into the test cup, which is maintained at the test

38、 temperature. After a specified time an ignition source is applied.The ability of the product to sustain combustion is assessed on the basis of its ability to ignite, when exposed to an ignition source, and whether it continues to burn after the ignition source has been removed.5 Apparatus5.1 Combus

39、tibility tester, as specified in Annex A.5.2 Electrical heater, attached to the bottom of the test cup in a manner that provides efficient transfer of heat. The heater control shall be capable of maintaining the test cup temperature, as measured on the temperature measuring device, and in a draught-

40、free area, within 0,5 C for test temperatures up to and including 100 C.NOTE The combustibility tester, heater and heater control unit can consist of an integrated apparatus.5.3 Gauge, for checking that the height of the centre of the gas jet above the top of the test cup is 2,2 mm 0,1 mm. A calibra

41、ted metal strip is suitable.5.4 Temperature measuring device.5.4.1 This shall be suitable for horizontal operation, and of suitable range and dimensions.5.4.2 Resolution to be able to be read to the nearest 0,5 C.5.4.3 Accuracy 0,5 C.5.4.4 When in position in the block, the temperature measuring dev

42、ice shall be surrounded with heat transfer paste to ensure good heat transfer between the block and the measuring device.NOTE It is recommended that the accuracy of the temperature measuring device be checked at least every 12 months or when indicated by a user verification check schedule.5.5 Stopwa

43、tch or other suitable timing device, capable of measuring 15 s 1 s, 30 s 1 s and 60 s 2 s. The timing device can be fitted with a means of producing an audible signal.5.6 Syringe or pipette, capable of delivering 2,00 ml to an accuracy of 0,05 ml.5.7 Ignition source and gas supply. The ignition sour

44、ce can be fuelled by natural gas, coal gas, butane or any other gas found to be suitable. The fuel supply to the gas jet shall be fitted with a suitable regulator, or other means of regulating the gas flow, such that the width of the flame can be adjusted to 4,0 mm 0,5 mm.5.8 Draught shield, to mini

45、mize draughts, fitted at the back and two sides of the instrument. A shield 350 mm high, 480 mm wide and 240 mm deep is suitable.5.9 Barometer, measuring absolute pressure, with an accuracy of 0,5 kPa. Do not use aneroid barometers pre-corrected to give sea level readings, such as those used at weat

46、her stations and airports.6DIN EN ISO 9038:2013-12EN ISO 9038:2013 (E) 6 Preparation of apparatus6.1 Do not carry out the test in a small confined area because of the risk of explosion.6.2 Thoroughly clean and dry the test cup and assembly before use, taking care not to damage the surface of the tes

47、t cup.6.3 Position the combustibility tester on a level, stable surface and away from strong light (to facilitate observation of a flash or flame). Ensure that the top of the metal block is horizontal.6.4 Use the gauge (5.3) to check that the jet is 2,2 mm 0,1 mm above the top of the block (see Figu

48、re A.2).6.5 It is essential that the apparatus is set up in a draught free area (see Notes 1 and 2). It can be necessary to surround the tester on three sides with a draught shield (5.8) for protection. If a fume hood is used, minimize the exhaust draught.NOTE 1 The air speed within 50 mm of the top

49、 of the test cup should preferably be less than 0,05 m/s.NOTE 2 Because the combustibility tester has an open test cup, the apparatus should always be used with a draught shield in place.7 Sampling7.1 Paints, varnishes and related productsTake a representative sample of the product to be tested, as described in ISO 15528, and examine and prepare it for testing, as described in ISO 1513.7.2 Petroleum and related products7.2.1 Sampling procedureTake
