23、 The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-
24、governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part
25、3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a
26、 vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. IS0 1523 was prepared jointly by Technical Committees ISO/TC 28, Pefroleurn prod
27、ucfs and lubricanfs and ISO/TC 35, Painfs and varnishes. This third edition cancels and replaces the second edition (IS0 1523:1983), which has been technically revised. Annex A of this International Standard is for information only. iv EN IS0 1523:2002 I nt rod uction This International Standard des
28、cribes one of two closed cup equilibrium methods for the determination of the flash point of paints, varnishes, petroleum and related products, and it should be read in conjunction with the second equilibrium method, IS0 3679 (5 in the bibliography), when selecting a method. The determination of the
29、 flashho flash temperature using the same equipment is described in IS0 1516 (4 in the bibliography). By the procedure specified, differences between test apparatus of various standard designs are minimized by ensuring that the test is carried out only when the product under test and the air/vapour
30、mixture above it in the test vessel are considered to be in temperature equilibrium. V EN IS0 1523:2002 EN IS0 1523:2002 Determination of flash point - Closed cup equilibrium method WARNING - The use of this International Standard may involve hazardous materials, operations and equipment. This Inter
31、national 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 applicability of regulatory limitations prior to use. 1 Scope T
32、his International Standard specifies a method to determine the flash point of paints, varnishes, paint binders, solvents, petroleum or related products. This International Standard is not applicable to water-borne paints which may, however, be tested using IS0 3679 (5 in the bibliography). The metho
33、d is suitable for use over the temperature range -30 OC to 110 OC, depending on the use of different apparatus listed in Table 1. The interpretation of results obtained from solvent mixtures containing halogenated hydrocarbons should be considered with caution, as these mixtures can give anomalous r
34、esults. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties t
35、o agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of IS0 and IEC maintain r

39、his International Standard, wherein ignition source is recognized as being a flame, the following term and definition apply. 3.1 flash point lowest temperature of the test portion, corrected to a barometric pressure of 101,3 kPa, at which application of an ignition source causes the vapour of the te
40、st portion to ignite and the flame to propagate across the surface of the liquid under the specified conditions of test 4 Principle The test portion is placed in a suitably designed closed cup mounted in a heating bath. The temperature of the bath is slowly raised at such a rate that the difference
41、in temperature between the liquid in the bath and the test portion in the cup never exceeds 2 OC, and the temperature of the test portion does not rise at a rate greater than approximately 0,5 OC in 13 min. During the heating-up period, ignition trials are carried out at intervals of not less than 1
42、,5 min. The lowest temperature at which a flash occurs is noted. 5 Chemicals and materials 5.1 Cleaning solvent, for removal of traces of the previous test portion from the test cup and cover. NOTE The choice of solvent will depend upon the previous material tested, and the tenacity of the residue.
43、Low volatility aromatic (benzene-free) solvents may be used to remove traces of oil, and mixed solvents such as toluene-acetone-methanol may be effective for the removal of gum-type deposits. 5.2 Verification liquids, see annex A. 6 Apparatus 6.1 standards listed in Table 1. Test cup and lid: a clos
44、ed cup with, where specified, an internal level indicator, and lid, as specified in the The test cup shall be fitted with a tightly fitting cover which carries an opening slide and an ignition device capable, when the slide is open, of positioning an ignition flame, with a diameter of between 3 mm a
45、nd 4 mm, at the approximate centre of the opening in the lid. When positioned, the tip of the ignition device shall be between the planes of the lower and upper surfaces of the lid at a point on a radius passing through the centre of the opening. The apparatus shall be designed such that an ignition
46、 trial can be performed by opening the slide, positioning and removing the nozzle of the ignition device, and closing the slide again in a period of between 2 s and 3 s. A mechanically driven device for carrying out this operation is permitted provided that it can be shown that it meets the specific
47、ation. NOTE The source of flame in the ignition device may be any suitable flammable gas. 6.2 Test cup thermometer, as specified for use with the test cup in the standards listed in Table 1. NOTE and have the same response as the thermometers specified in the standards listed in Table 1. Other types
48、 of temperature measuring devices may be used provided that they meet the requirements for accuracy 6.3 (see 10.10), and of adequate size and heat capacity to meet the requirements of 10.10.
