The work of preparin
28、g International Standards is normally carried out through ISO 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-governmental, in liai
29、son with ISO, also take part in the work. ISO 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 3. The main task of t
30、echnical 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 vote. Attention is d
31、rawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1523 was prepared jointly by Technical Committees ISO/TC 28, Petroleum products and lubricants an

33、0 2006, Uncontrolled Copy, (c) BSI v Introduction This International Standard describes 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, IS
34、O 3679 (5 in the bibliography), when selecting a method. The determination of the flash/no flash temperature using the same equipment is described in ISO 1516 (4 in the bibliography). By the procedure specified, differences between test apparatus of various standard designs are minimized by ensuring
35、 that the test is carried out only when the product under test and the air/vapour mixture above it in the test vessel are considered to be in temperature equilibrium.

This International
37、 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 This Inte
38、rnational 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 ISO 3679 (5 in the bibliography). The method is sui
39、table for use over the temperature range 30 C to 110 C, 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 results. 2 N
40、ormative 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 to agreement

45、, Uncontrolled Copy, (c) BSI 2 3 Term and definition For the purposes of this 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 k
46、Pa, at which application of an ignition source causes the vapour of the test 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 te
47、mperature of the bath is slowly raised at such a rate that the difference in temperature between the liquid in the bath and the test portion in the cup never exceeds 2 C, and the temperature of the test portion does not rise at a rate greater than approximately 0,5 C in 1,5 min. During the heating-u
48、p period, ignition trials are carried out at intervals of not less than 1,5 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 de
49、pend upon the previous material tested, and the tenacity of the residue. 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 Test cup and lid: a closed cup with, where specified, an internal level indicator, and lid, as specified in the standards listed in Table 1. The test cup shall be fitted with a tightly fitting cover which c
