3、 standard has been developed is a government agency within the Federal Department of Supply and Services. The CCSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are co
4、mposed of representatives of relevant interests induding producers, consumers and other users, retailers, governments, educational institutions, tech- nical, professional and trade societies, and research and test- ing organizations. Any given standard is developed on the consensus of views expresse
5、d by such representatives. The Ministers Advisory Council on CCSB reviews the results of the consensus process. The CCSB has been accredited by the Standards Council of Canada as a national standards-writing organization. The standards that it develops and offers as National Standards of Canada conf
6、orm to the criteria and procedures established for this purpose by the Standards Council of Canada. In addition to standards it publishes as national standards, the CCSB produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sect
7、ors. Both CCSB standards and national standards developed by the CGSB are developed in conformance with the policies described in the Policy Manual for the Development and Maintenance of Standards by CGSB. CCSB standards are subject to review and revision at any time, so as to ensure that they keep
8、abreast of technological progress. Suggestions for their improvement, which are al- ways welcome, should be brought to the notice of the stand- ards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards. An up-tedate listing of CGSB
9、 standards, including details on latest issues and amendments, and ordering instructions, will be found in the Catalogue of Standards and Qualified Products Lists which is published annually and is available without charge upon request. Although the intended primary application of this standard is s
10、tated in its Scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitabil- ity for their particular purpose. Many tests required by CCSB standards are inherently hazard- ous. The CCSB neither assumes nor accepts any responsibility for any injur
11、y or damage that may occur during or as the result of tests, wherever performed. The CCSB takes no position respecting the validity of any patent rights asserted with any item connected with this standard. Users of this standard are expressly advised that determination of the validity of any such pa
12、tent rights are entirely their own responsibility.

42、ve frame without distortion, looseness or waviness. The joint between the wire cloth and the frame shall be smoothly filled with solder, or otherwise fashioned so that the joint shall have no influence on the determination of particle size by the sieve. The joint or fillet shall be so constructed as
43、 to allow a minimum free-sieving surface of not less than 7-112 in diameter for a sieve having a nominal diameter of 8 in. The per cent effective sieving surface of other sizes of sieves shall be within this tolerance. 4.4 The sieves shall be free from obvious imperfections or defects in workmanship
44、 and material. 5. DETAIL REQUIREMENTS 5.1 Aperture Tolerances - The wire cloth used in a sieve shall conform to the dimensional requirements in Table 1. The average apertures in both the warp and shoot (weft) directions, measured separately, shall conform to the values for the sieve designation with
45、in the permissible variation given. In no case shall any individual aperture exceed the value given for the maximum individual aperture, nor more than 5% of the openings exceed the value given in Table 1. All measurements of apertures shall be made on wire cloth mounted in the completed sieve. 5.2 A
46、ngle Tolerance - With the exception of any twilled weave item the warp and shoot (weft) wires shall be perpendicular to each other after mounting within a maximum deviation of 8 from the perpendicular based on the mean direction of wires over several meshes. 2Y sin 8 = - W where: W is the standard s
47、ieve designation Y is the permissible variation of average aperture from the standard sieve designation. 5.3 Wire diameter tolerances - The wire diameters given in Table 1 apply to woven wire cloth mounted in a frame. The average diameter of the wires in the cloth of any sieve, in both the warp and
48、shoot (weft) directions, measured separately, shall not deviate from the nominal values given in Table 1 by more than * 15%. These calculated averages for the diameters shall be made from a random selection of the wires. = 1874650 0009928 715 Les montures, les rceptacles et les couvercles des tamis
