36、 wire cloth. The frame of the test sieves shall be made of metaI. The range of nominal mesh apertures depends on the specification for the product to be tested and shall comply with the requirements of Table 2 in ISO 565:1990, as indicated in Table 1. The sieves shall have square openings. A lid and
37、 a residue pan shall also be provided.NOTE Smaller-diameter sieves might not produce accurate separation of the sample.Sieves shall be regularly checked for calibration and freedom from retained abrasive.DIN EN ISO 11127-2:2012-04 EN ISO 11127-2:2011 (E) 4 Table 1 List of sieve mesh apertures to be

41、 under test as given in the grade and screening specification table in the appropriate part of ISO 11126 (see Annex A) or, in the case of materials not covered by ISO 11126, as otherwise agreed between the interested parties.5.4 Arrange the test sieves (3.1) with the largest-aperture sieve on the to
42、p and progress to the smallest aperture at the bottom, with a pan to catch any abrasive that falls through the finest sieve.5.5 Place the test portion in the top sieve.5.6 Place a cover over the top sieve.5.7 Place the stack of sieves with the test portion in the rotating sieve machine (3.2) and ope
43、rate the sieve machine for 15 min.5.8 Carefully remove the top sieve from the stack and transfer any retained abrasive on to the balance pan. Brush the sieve clean of any trapped abrasive and add this to the balance pan. Weigh to the nearest 0,1 g and record this result (m1). Repeat for all the siev
44、es in the stack, including the retaining pan.DIN EN ISO 11127-2:2012-04 EN ISO 11127-2:2011 (E) 5 6 Expression of resultsFor each test sieve used, and for the residue in the pan, calculate the percentage of material retained R, expressed as a percentage by mass, using the equationRmm= 10100wherem0is
45、 the mass, in grams, of the test portion;m1is the mass, in grams, of the residue on the sieve (or in the pan).If the duplicate determinations differ by more than 10 % (relative to the higher result), repeat the procedure described in Clause 5.Calculate the mean of two valid determinations and report
46、 the result to the nearest 1 %.7 Test reportThe test report shall contain at least the following information:a) all details necessary to identify the product tested, in accordance with the appropriate part of ISO 11126 (see Annex A), if applicable;b) a reference to this part of ISO 11127 (ISO 11127-
