15、0ISO 9117-2:2010(E) ISO 2010 All rights reserved iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Ea

16、ch 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 liaison with ISO, also take part in the work. ISO collaborates closely with the Internatio

17、nal 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 2. The main task of technical committees is to prepare International Standards. Draft International Standar

18、ds 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 drawn to the possibility that some of the elements of this document may be the subject

19、of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 9117-2 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes. This first edition of ISO 9117-2 cancels and replaces I

20、SO 4622:1992, which has been technically revised. The main changes are as follows: a) the method has been integrated into the ISO 9117 series as Part 2, for determination of the drying of paints and varnishes; b) a “terms and definitions” clause has been added; c) a “principle” clause has been added

21、; d) the requirement for relative humidity during the procedure has been deleted, i.e. it is not necessary to carry out the test in a climate chamber; e) text from the former annex A headed “required supplementary information” has been integrated into the test report. ISO 9117 consists of the follow

22、ing parts, under the general title Paints and varnishes Drying tests: Part 1: Determination of through-dry state and through-dry time Part 2: Pressure test for stackability Part 3: Surface-drying test using ballotini The following parts are under preparation: Part 4: Test using a mechanical recorder

24、standard conditions, 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 intend

25、ed to simulate 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、finitions apply. 3.1 stackability resistance to damage due to unwanted adhesion between adjacent surfaces of articles that develops when these articles are left in contact BS EN ISO 9117-2:2010ISO 9117-2:2010(E) 2 ISO 2010 All rights reserved4 Principle A coat of paint or varnish is applied to a sub

29、strate and is allowed to dry under 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

30、for any damage to the coating in 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 plu

31、nger is aligned with the top surface 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.

Examine and prepare each sample for testing in accordance with IS

33、O 1513. 7 Test panels 7.1 Substrate Select the substrate 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 met

34、hod with the product or system under test. 7.3 Drying 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 pi

35、eces As soon as possible after the specified drying 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

36、 remains as planar as possible. Remove any rim raised 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 th

37、is case, Clause 9 shall be applied. If the interaction 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

38、 ISO 2808. 8 Procedure 8.1 Carry out the procedure 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 fac

39、ing each other are in close contact (see plan view 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. BS EN ISO 9117-2:2010ISO 9117-2:2010(E) 4 ISO 2010 All rights reservedKey

40、l width of the square of the overlapping test pieces in contact (see 7.4) 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 th

41、e contact square entirely. Place the weight on the plunger and gently 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 perio

42、d, remove the plunger, separate the test pieces and examine them for any 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 b

43、e stated in the test report. 8.5 Repeat the procedure in 8.2 to 8.4 on 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 pl

44、unger assembly; m2is the mass, in grams, of the weight; m3is the mass, 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).
