7、reword This Part of BS 3900 has been prepared under the direction of the Surface Treatments and Coatings Standards Policy Committee. It is identical to ISO 1517:1973 Paints and varnishes Surface-drying test Ballotini method, published by the International Organization for Standardization (ISO). It s
8、upersedes BS 3900-C2:1971, which is withdrawn. In 1995 the European Committee for Standardization (CEN) accepted ISO 1517:1973 as European Standard EN ISO 1517:1994. As a consequence of implementing the European Standard is renumbered as BS EN ISO 1517:1995 and any reference to BS 3900-C2 should be
9、read as a reference to BS EN ISO 1517. The main differences between this revision and BS 3900-C2:1971 are as follows: a) The temperature for the test is now (23 2) C. b) The relative humidity for the test is now (50 5) %. The Technical Committee has reviewed the provisions of ISO 1514:1993, to which
10、 normative reference is made in the text, and has decided that they are acceptable for use in conjunction 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 application. Complianc
11、e with a British Standard does not of itself confer immunity from legal obligations.

24、 one of a series dealing with the sampling and testing of paints, varnishes and related products. It should be read in conjunction with ISO 1512, ISO 1513 and ISO 1514. The method of test specified requires to be completed, for any particular application, by the following supplementary information.
25、This information should be derived from the national standard or other document for the material under test or, where appropriate, should be the subject of agreement between the interested parties. a) Nature and surface preparation of substrate. b) Method of application of test coating to substrate.
26、 c) Thickness, in micrometres, of the dry coating, including method of measurement, and whether it is a single coating or a multicoat system. d) Duration and conditions of drying of primer and/or undercoat before testing. e) Duration of drying before testing, if applicable. 1 Scope and field of appl
27、ication 1.1 This International Standard specifies a method for determining the surface-drying characteristics of a coating of a paint or varnish which dries by the action of air or by chemical reaction of its components. The method is not intended to apply to stoving products. 1.2 The method describ
28、ed may be carried out either as a “go/no go” test, by determining the surface-drying state after a specified time, to assess compliance with a particular requirement, or by determining the surface-drying state at suitable intervals until the surface-drying time is obtained. 2 References ISO 1512, Pa

30、he state of the surface of a coating of paint or varnish, i.e. whether “surface-dry” or not 3.2 surface-dry surface-drying state of a coating of paint or varnish when ballotini can be lightly brushed away without damaging the surface of the coating 3.3 surface-drying time period of time between that
31、 at which a coating of paint or varnish is applied to a prepared test panel and that at which the coating is assessed as just surface-dry by the test procedure specified in clause 7 4 Apparatus 4.1 Ballotini (small transparent glass spheres) The material shall be obtained by sieving from a suitable
32、commercial grade of ballotini and shall be graded so that none passes a sieve of nominal mesh aperture 125 m and all passes a sieve of nominal mesh aperture 250 m. 4.2 Brush, soft-haired 4.3 Stop-watch or stop-clock. 5 Sampling A representative sample of the product to be tested shall be taken as sp
33、ecified in ISO 1512. The samples shall be examined and prepared for testing as specified in ISO 1513. 6 Test panels 6.1 Material and surface preparation Unless otherwise specified or agreed, the test panel shall be of glass, burnished steel, burnished tinplate or burnished aluminium complying with t
34、he requirements of ISO 1514, and the surface shall be prepared for painting as specified therein. 6.2 Coating the panel 6.2.1 If required, the test panel shall be coated with the appropriate primer and/or undercoat and allowed to dry for an agreed period before applying the product under test. 6.2.2
35、 The test panel shall be coated with the product under test by the specified or agreed method of application.

36、ed test panel to dry in a vertical position, shielded from air currents, in the absence of direct sunlight and under ambient conditions of 23 2 C and 50 5 % relative humidity, unless otherwise stated. 7.2 Assessment of surface-drying state after a specified time 7.2.1 After the completion of the spe
37、cified time, place the test panel in a horizontal position. 7.2.2 Pour approximately 0,5 g of the ballotini (4.1) onto the surface of the coating from a height of not less that 50 mm and not more than 150 mm. NOTEIt is convenient to pour the ballotini down a glass tube of appropriate length and with
38、 an internal diameter of approximately 25 mm, in order to avoid undue spreading of the ballotini and thus enable further tests to be made, if necessary, on other areas of the same panel. 7.2.3 After 10 s, hold the panel at an angle of 20 to the horizontal and brush the coating lightly. 7.2.4 Examine
39、 the surface of the coating, using normal corrected vision. The coating is “surface-dry” if all the ballotini can be brushed away without damage to the surface. 7.3 Determination of surface-drying time Prepare a number of similar coated test panels as specified in clause 6 and allow to dry as specif
40、ied in 7.1. At appropriate intervals, starting shortly before the coating is expected to be surface-dry and using a different panel for each test (or an untouched area of the same panel, if the tube described in the Note to 7.2.2 is used) carry out the test as specified in 7.2 until the test shows t
41、he coating to be surface-dry. Record the time taken for the coating to become just surface-dry. 7.4 Determination of thickness of coating Determine the thickness, in micrometres, of the dry coating by the method specified, using one of the procedures specified in ISO 2808. 8 Test report The test rep
42、ort shall include the following information: a) a reference to this International Standard or to a corresponding national standard; b) the type and identification of the product under test; c) the items of supplementary information referred to in the Introduction to this International Standard; d) t
43、he national standard or other document supplying the information referred to in c) above; e) any deviation, by agreement or otherwise, from the test procedure specified; f) the result of the test; report, as required: either whether or not the coating was “surface-dry” after the specified time, or t
44、he “surface-drying time”; g) the date of the test.
