24、itions, whether a single-coat film or a multi-coat system of paints or related materials, after a specified drying period, is sufficiently dry to resist damage when two painted surfaces or one painted surface and another surface are placed in contact under pressure. The method is intended to simulat
25、e the conditions when painted articles are stacked upon each other. NOTE In some countries, the test is called a “block resistance” test. 2 Normative references The following referenced documents are indispensable for the application of this document.

28、ly. 3.1 stackability resistance to damage due to unwanted adhesion between adjacent surfaces of articles that develops when these articles are left in contact DIN EN ISO 9117-2:2010-07 EN ISO 9117-2:2010 (E) 4 4 Principle A coat of paint or varnish is applied to a substrate and is allowed to dry und
29、er specified conditions. The coated test panel is cut into strips, and two strips are placed so that the test surfaces are in close contact. This assembly is placed in a test apparatus and loaded with weights. After a specified period of time, the panels are examined for any damage to the coating in
30、 the area of contact. 5 Apparatus 5.1 Test apparatus, e.g. as shown in Figure 1, consisting of a baseplate and a free-sliding plunger. The plunger, with a head of diameter (50 1) mm, shall have a mass of (250 2) g and be designed in such a way that the face of the plunger is aligned with the top sur
31、face of the test panel. It is recommended that a ball joint connection be present between the plunger and its head. 5.2 Weights, of mass in the range 100 g to 1 000 g.

32、0-07 EN ISO 9117-2:2010 (E) 5 6 Sampling Take a representative sample of the product to be tested (or of each product in the case of a multi-coat system) in accordance with ISO 15528. Examine and prepare each sample for testing in accordance with ISO 1513. 7 Test panels 7.1 Substrate Select the subs
33、trate from one of those described in ISO 1514 and, where possible, in accordance with the intended practical application. 7.2 Preparation and coating Prepare each test panel (see 7.1) in accordance with ISO 1514 and then coat it by the specified method with the product or system under test. 7.3 Dryi
34、ng Dry (or stove) and age, if applicable, each coated test panel in a horizontal position with free circulation of air, but shielded from draughts and direct sunlight, for the specified time under the specified conditions. 7.4 Preparation of test pieces As soon as possible after the specified drying
35、 period, prepare from the test panels at least six strips of width l = (30 1) mm and length approximately five times the width, in such a manner as to: avoid damage to the paint film; produce the least distortion of the substrate; and ensure that it remains as planar as possible. Remove any rim rais
36、ed on the test pieces before testing. If the preparation of appropriate test pieces with dimensions as given above is unfeasible, because the coating to be tested can be easily damaged, test pieces may be used of dimensions up to 100 mm 75 mm. In this case, Clause 9 shall be applied. If the interact
37、ion between the painted surface and another surface is to be determined, prepare a similar test piece of the other material. 7.5 Thickness of coating Determine the thickness, in micrometres, of the dried coating by one of the procedures specified in ISO 2808. 8 Procedure 8.1 Carry out the procedure
38、in triplicate at standard temperature (23 2) C and ambient relative humidity (see ISO 3270). The relative humidity during the test shall be measured and stated in the test report. 8.2 Superpose the test pieces at (90 2) so that the test surfaces facing each other are in close contact (see plan view
39、in Figure 2). Arrange the test pieces so that the areas least damaged during preparation are superposed. NOTE A set square may be used to ensure that the test area is square. DIN EN ISO 9117-2:2010-07 EN ISO 9117-2:2010 (E) 6 Key l width of the square of the overlapping test pieces in contact (see 7
40、.4) NOTE The length of the test piece is approximately five times the width (see 7.4). Figure 2 Plan view of typical arrangement of test pieces 8.3 Place the test pieces on the baseplate in such a manner that the plunger covers the contact square entirely. Place the weight on the plunger and gently
41、place the total mass in contact with the test pieces. Allow it to remain there for the specified time. The weight and the time of contact under load have to be specified between the interested parties. 8.4 At the end of this period, remove the plunger, separate the test pieces and examine them for a
42、ny damage to the coating in the area of contact, e.g. the presence of visible impressions, any sticking of the test pieces, and any detachment of the coating. The time elapsed between removal of the weights and examination shall be stated in the test report. 8.5 Repeat the procedure in 8.2 to 8.4 on
43、 two additional test arrangements. 9 Calculation of pressure The pressure, p, in pascals, on the painted surfaces may be calculated from the following equation: 123 32123 421010mmmpglmmml+=+where m1is the mass, in grams, of the plunger assembly; m2is the mass, in grams, of the weight; m3is the mass,
44、 in grams, of the upper test piece; l is the width, in millimetres, of the square of the overlapping test pieces in contact (see Figure 2); g is the acceleration of free fall, in newtons per kilogram (approximately 10 N/kg).

48、8.1); e) the combined mass of the plunger and weight (i.e. test load) or the pressure to be used (see 8.3); f) the duration of contact under load of the two pieces (see 8.3); g) the time elapsed between removal of the weights and examination (see 8.4); h) the results of the test in terms of the stated requirements and a description of any damage (see 8.4); i) any unusual features (anomalies) observed during the test; j) any deviations from the test procedure specified; k) the date of the test.
