7、6, Uncontrolled Copy, (c) BSI BS EN ISO 4622:1995 ii BSI 03-2000 National foreword This Part of BS 3900 has been prepared under the direction of the Pigments, Paints and Varnishes Standards Policy Committee. It is identical with ISO 4622:1992 Paints and varnishes Pressure test for stackability, publ
8、ished by the International Organization for Standardization (ISO). In 1994, the European Committee for Standardization (CEN) accepted ISO 4622:1992 as European Standard EN ISO 4622:1994. This edition supersedes BS 3900-C7:1982, which is withdrawn. The difference between BS 3900-C7:1982 and this stan
9、dard is that provisions are now included for larger test pieces. This standard makes reference to the forthcoming revision of ISO 1514. ISO 1514:1984 is identical with BS 3900-A3:1986 Standard panels for paint testing. The Committee has reviewed the provisions of ISO 1514:1983 to which normative ref
10、erence is made in the text and has decided that, until the revision is published, they are acceptable for use in conjuction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct appl
11、ication. Compliance with a British Standard does not of itself confer immunity from legal obligations.

20、N ISO 4622:1994 BSI 03-2000 2 Foreword This European Standard has been taken over by the Technical Committee CEN/TC 139, Paints and varnishes, from the work of ISO/TC 35, Paints and varnishes, of the International Organization for Standardization (ISO). This European Standard shall be given the stat
21、us of a national standard, either by publication of an identical text or by endorsement, at the latest by February 1995, and conflicting national standards shall be withdrawn at the latest by February 1995. According to the CEN/CENELEC Internal Regulations, the following countries are bound to imple
22、ment this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

25、 and testing of paints, varnishes and related products. This International Standard specifies a test method for determining, under 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 damag
26、e when two painted surfaces or one painted surface and another surface are placed in contact under pressure. The method is intended to simulate the conditions when painted articles are stacked upon each other. NOTE 1In some countries, the test is called a “block resistance” test. 2 Normative referen
27、ces The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Stan
28、dard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

The items of supplementary information are given in Annex A. 4 Apparatus 4.1 Test apparatus, a
31、s shown in Figure 1, consisting of a base-plate and a free-sliding plunger. The plunger, with a head of diameter (50 1) mm, shall have a mass not exceeding 250 g and be designed in such a way that the face of the plunger is aligned with the top surface of the test panel. NOTE 2It is recommended that
32、 a balljoint connection be present between the plunger and its head. 4.2 Weight, of a mass suitable for the coating and its intended application. NOTE 3A mass in the range 100 g to 1 000 g will normally be suitable. 5 Sampling Take a representative sample of the product to be tested (or of each prod
33、uct in the case of a multi-coat system), as described in ISO 1512. Examine and prepare each sample for testing, as described in ISO 1513. 6 Test panel 6.1 Substrate Unless otherwise agreed, select the substrate from one of those described in ISO 1514 and, where possible, in accordance with the desir
34、ed practical application. 6.2 Preparation and coating Unless otherwise agreed, prepare each test panel in accordance with ISO 1514 and then coat it by the specified method with the product or system under test. 6.3 Drying Dry (or stove) and age (if applicable) each coated test panel for the specifie
35、d time under the specified conditions. 6.4 Preparation of-test pieces As soon as possible after the specified drying period, prepare from the test panels at least six strips preferably of width (30 1) mm and length approximately five times the width, in such a manner as to avoid damage to the paint
36、film, to produce the least distortion of the substrate and to ensure that it remains as plane as possible. Remove any rim raised on the test pieces before testing. 1) To be published.

37、lled Copy, (c) BSI EN ISO 4622:1994 4 BSI 03-2000 If the preparation of adequate test pieces with dimensions as given above is shown to be impossible because the coating to be tested may be easily damaged, test pieces may be used of dimensions up to 100 mm 75 mm. In this case, clause 8 shall be appl
38、ied. If the interaction between the painted surface and another surface is to be determined, prepare a similar test piece of the other material. 6.5 Thickness of coating Determine the thickness, in micrometres, of the dried coating by one of the procedures specified in ISO 2808. 7 Procedure 7.1 Carr
39、y out the procedure in triplicate at (23 2) C and a relative humidity of (50 5) %, unless otherwise agreed (see also ISO 3270). 7.2 Superimpose the test pieces at (90 2) so that the test surfaces are in close contact (see plan view in Figure 2). Arrange the test pieces so that the areas fast damaged
40、 during preparation are superimposed. NOTE 4A set square may be used to ensure that the test area is square. 7.3 Place the test pieces on the base plate in such a manner that the plunger covers entirely the contact square. Place the agreed weight on the plunger and gently place the total mass in con
41、tact with the test pieces. Allow it to remain there for the specified time.

42、 BSI 03-20005 7.4 At the end of this period, remove the plunger, separate the test pieces and examine them for any damage to the coating in the area of contact; for example, the presence of visible impressions, any sticking of the test pieces, and any detachment of the coating. 8 Expression of resul
43、ts If desired, the pressure p, in pascals, on the painted surfaces may be calculated from the following equation: where 9 Precision No precision data are currently available. 10 Test report The test report shall contain at least the following information: a) all details necessary to identify the pro
44、duct tested; b) a reference to this International Standard (ISO 4622); c) the items of supplementary information referred to in Annex A; d) a reference to the international or national standard, product specification or other document supplying the information referred to in c); e) the results of th
