Additional information

6、 regarding this test method: The importance of the cross-cut test as a field test in the construction sector should not be underestimated. For substrates that are inhomogeneous and/or that have a considerably lower cohesion than the coating being tested (e.g. certain plaster surfaces) it is not poss

7、ible to make cuts having a uniformly low depth. This method is therefore not suitable for such substrates. The results of field tests on coatings with different exposure conditions and carried out at different times are not comparable. Normally, climatic conditions do not remain constant over time a

8、nd they vary from location to location; for this reason the test conditions specified in this standard cannot be maintained in field tests. The DIN Standards corresponding to the International Standards referred to in this document are as follows: ISO 1513 DIN EN ISO 1513 ISO 1514 DIN EN ISO 1514 IS

10、 loose paint have been transferred 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

11、; c) a cutting tool used with automatic cross-cut apparatus has also been specified; d) the pictorial standard for classification 2 has been replaced by one originally used in the first edition (1972) and the second edition (1992) of this International Standard; e) in Subclause 6.1.4, plastics have

12、been added as an example of a hard substrate; f) a designation code has been introduced to indicate the test result; g) the supplementary test conditions previously given 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 mo

13、tor-driven) and the type of cutting tool used have an influence on the test result.

Foreword“”3DIN EN ISO 2409:2013-06 EN ISO 2409:2013 (E) 1 ScopeThis International Standard specifies a test met

30、hod for assessing the resistance of paint coatings to separation from substrates when a 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

31、either the preceding coat or the substrate. This procedure is not to be regarded, however, 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

32、also suitable for field testing.The method described may be used either as a pass/fail 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

33、can be made.The test can be carried out on finished objects and/or on specially prepared 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

34、 not suitable for coatings of total thickness greater than 250 m or for textured coatings.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 reference

38、out the total coating thickness, and that the cutting edges are in 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

39、 multi-blade cutting tool (3.2.3) is not suitable for thick (120 m) 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 app

40、aratus, which gives more uniform cutting. The application of the latter 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 c

43、defined manner so that a sharp blade is available at any time.3.2.3 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 hav

44、e six cutting edges spaced 1 mm, 2 mm or 3 mm apart. In addition, two 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. This informa
