18、dards bodies (ISO member bodies). The work of preparing 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 org
19、anizations, governmental and non-governmental, in liaison 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
20、in the ISO/IEC Directives, Part 2.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 %
21、 of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 2409 was prepared by Technical Committee ISO/TC 35, Paints an
22、d varnishes, Subcommittee SC 9, General test methods for paints and varnishes.This fourth edition cancels and replaces the third edition (ISO 2409:2007), which has been technically revised. The main changes are as follows:a) the description of suitable methods for removal of loose paint have been tr
23、ansferred to an informative annex as examples and, for the method using adhesive tape, the adhesive strength of the tape is no longer specified;b) the single-blade cutting tool originally used in the first edition (1972) of this International Standard has been re-introduced;c) a cutting tool used wi
24、th automatic cross-cut apparatus has also been specified;d) the pictorial standard for classification 2 has been replaced by one originally used in the first edition (1972) and the second edition (1992) of this International Standard;e) plastics have been added as an example of a hard substrate in 6
25、.1.4;f) a designation code has been introduced to indicate the test result;g) the supplementary test conditions previously in Clause 7 have been integrated in the test report;h) a note has been added to Subclause 3.2.1 that the apparatus (manual or motor-driven) and the type of cutting tool used hav
26、e an influence on the test result.iv ISO 2013 All rights reservedBS EN ISO 2409:2013INTERNATIONAL STANDARD ISO 2409:2013(E)Paints and varnishes Cross-cut test1 ScopeThis International Standard specifies a test method for assessing the resistance of paint coatings to separation from substrates when a
27、 right-angle lattice pattern is cut into the coating, penetrating through to the substrate. The property determined by this empirical test procedure depends, among other factors, on the adhesion of the coating to either the preceding coat or the substrate. This procedure is not to be regarded, howev
28、er, as a means of measuring adhesion.Where a measurement of adhesion is required, the method described in ISO 46241may be used.NOTE 1 Although the test is primarily intended for use in the laboratory, the test is also suitable for field testing.The method described may be used either as a pass/fail
29、test or, where circumstances are appropriate, as a six-step classification test. When applied to a multi-coat system, assessment of the resistance to separation of individual layers of the coating from each other can be made.The test can be carried out on finished objects and/or on specially prepare
30、d test specimens.Although the method is applicable to paint on hard (e.g. metal) and soft (e.g. wood and plaster) substrates, these different substrates need a different test procedure (see Clause 6).The method is not suitable for coatings of total thickness greater than 250 m or for textured coatin
31、gs.NOTE 2 The method, when applied to coatings designed to give a rough patterned surface, will give results which will show too much variation (see also ISO 16276-22).2 Normative referencesThe following referenced documents are indispensable for the application of this document.

34、ary laboratory apparatus, together with the apparatus specified in 3.2 to 3.4.3.2 Cutting tool3.2.1 General requirementsIt is particularly important to ensure that the cutting tool is capable of creating the specified V-shape throughout the total coating thickness, and that the cutting edges are in
35、good condition. Suitable tools are described in 3.2.2 and 3.2.3 and shown in Figures 1 and 2.A single-blade cutting tool (3.2.2) is the preferred tool in all cases, i.e. with all kinds of coating on both hard and soft substrates. The multi-blade cutting tool (3.2.3) is not suitable for thick (120 m)
36、 or hard coatings or where the coating is applied over soft substrates.The tools described in 3.2.2 and 3.2.3 are suitable for manual use, which is the more usual method of use, but the tools may also be mounted on a motor-driven apparatus, which gives more uniform cutting. The application of the la
37、tter procedure shall be subject to agreement between the interested parties.NOTE The apparatus (manual or motor-driven) and the type of cutting tool used have an influence on the test result.Results obtained with different types of cutting tool cannot be directly compared.3.2.2 Single-blade cutting
38、tools3.2.2.1 Hand-held single-blade cutting tool with a cutting edge as shown in Figure 1a).3.2.2.2 Single-blade cutting tool used in motor-driven apparatus as shown in Figure 3.3.2.2.3 Cutter with a rigid blade with a V-shaped cutting edge as shown in Figure 1b), e.g. a Cutter 3011)as illustrated i
39、n Annex A of ISO 17872:2007.3The thickness of the blade may be disregarded as long as the blade is rigid and the cut produced is V-shaped through the whole thickness of the coating.NOTE The cutter blade is designed to be broken in a defined manner so that a sharp blade is available at any time.3.2.3
40、 Multi-blade cutting tools3.2.3.1 Hand-held multi-blade cutting tool with cutting edges as shown in Figure 2.3.2.3.2 Multi-blade cutting tool used in motor-driven apparatus as shown in Figure 3. The multi-blade cutting tool shall have six cutting edges spaced 1 mm, 2 mm or 3 mm apart. In addition, t
41、wo guide edges (see Figure 2) are necessary to make handling easier. The guide edges and the cutting edges shall lie on the same diameter (see Figure 2).1) This is an example of a suitable product available commercially.
