24、dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standa
25、rd only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 21512, Paints and varnishes Sampling of products in liquid or paste form (ISO 1512:1991). EN ISO 1514, Paints and varnishes Standard panels for testing (ISO
26、1514:1993). 3 Test method The maximum particle size of the filler is the reading obtained on a standard gauge under specified conditions of test, indicating the depth of the groove of the gauge at which discrete solid particles in the product are readily discernible. 4 Apparatus 4.1 Gauge, consistin
27、g of a block of stainless steel approximately 175 mm long, 65 mm wide and 13 mm thick. The top surface of the block shall be both plane and ground smooth and shall contain one or two grooves approximately 140 mm long and 12,5 mm wide parallel to the longer sides of the block. The depth of each groov
28、e shall be uniformly tapered along its length from a suitable depth (for example 50 m, 100 m, 250 m or 500 m) at one end to zero depth at the other end and shall be graduated as specified in Table 1. Diagrams of typical gauges are given in Figure 1. The depth of the groove at any position along its
29、length shall not depart from its nominal value at any position across the groove by more than 2,5 m. A method of checking the groove depth is described in annex A.

31、all be flat so that all points lie between two parallel planes 12 m apart and, in addition, at every position along the surface, the transverse generator shall be straight so that all points along it lie between two parallel straight lines 1 m apart. The top and bottom surfaces of the block shall be
32、 parallel within 25 m. NOTE The precision of the maximum particle size determination depends in part on which gauge is used (see clause 6). Therefore it is essential to identify the gauge (500 m, 250 m, 100 m, 50 m) when reporting results or specifying requirements. 4.2 Scraper, consisting of a sing
33、le- or doubled-edged steel blade approximately 90 mm long, 40 mm wide and 6 mm thick. The edge(s) on the long side(s) shall be straight and rounded to a radius of approximately 0,25 mm. A drawing of a suitable scraper is shown in Figure 2. The scraper shall be periodically checked for wear, damage o
34、r warping by placing the edge of the scraper on the reference plane surface (see A.2.3) and inspecting the contact edge against a strong light. Reject the scraper if poor contact between the edge of the scraper and the reference plane surface is revealed when the scraper is rocked backwards and forw
35、ards. NOTE 1 The top surface of the gauge can be used for routine checking of the scraper, provided that it itself is not worn or warped and verified by use of the reference plane surface. NOTE 2 When not in use, the scraper should be stored in a container lined with velvet or similar soft material.
36、 5 Sampling Take a representative sample of the product to be tested as specified in EN 21512. Examine and prepare the sample for testing as specified in EN ISO 1514. 6 Test procedure 6.1 Carry out a preliminary determination to establish the size of gauge most suitable for the test and the approxim
37、ate maximum particle size of the test sample (see Table 1 and the note to 6.5). This approximate determination shall not be included in the results of the test. Then carry out the determination in triplicate. 6.2 Place the gauge (4.1), which shall be thoroughly clean and dry, on a flat, horizontal,
38、nonslip surface. 6.3 Pour a sufficient amount of sample into the deep end of the groove so that it overflows the groove slightly. Take care that during pouring the sample does not trap any air.

39、 Page 6 EN 12192-2:1999 BSI 09-1999 6.4 Grasp the scraper (4.2) between the thumbs and fingers of both hands and place it edgewise in contact with the surface of the gauge at the extreme deep end of the groove with the length of the scraper parallel to the width of the gauge. While holding the scrap
40、er perpendicular to the surface of the gauge and at right angles to the length of the groove, draw it at a uniform rate over the surface of the gauge to a point beyond the zero depth of the groove in 1 s to 2 s. Apply sufficient downward pressure on the scraper to ensure that the groove is filled wi
41、th the sample and that any surplus is removed. 6.5 In a time not exceeding 3 s from the completion of the drawdown, view the gauge from the side in such a manner that the line of vision is at right angles to the long dimension of the groove and at an angle of not more than 30 nor less than 20 to the
42、 surface of the gauge while it is in a light that will make the pattern on the sample in the groove readily visible. NOTE If the rheology of the sample is such that a smooth pattern is not obtained after drawdown, a minimal quantity of an appropriate thinner or blinder solution can be added to the s
43、ample by hand stirring, and the test repeated. Any dilution should be stated in the test report. In some instances, the dilution of the sample can lead to flocculation and the fineness of grind can be affected. 6.6 Observe the point where the product first shows a predominantly speckled appearance a
44、nd, in particular, where a 3 mm wide band across the groove contains five to ten particles (see Figures 3 and 4). Disregard any scattered specks that may appear prior to the point where the predominantly speckled appearance begins. Estimate the position of the upper limit to the nearest: a) 20 m for
45、 the 500 m gauge; b) 10 m for the 250 m gauge; c) 5 m for the 100 m gauge; d) 2 m for the 50 m gauge. 6.7 Clean the gauge and scraper carefully with a suitable solvent immediately after each reading. 7 Expression of results Calculate the mean of the three determinations and record the result to the
46、same precision as the original readings (see 6.6).
