Test sieves - Technical requirements and testing - Part 1: Test sieves of metal wire cloth 1 Scope This document specifies the technical requirements and corresponding test methods for test sieves of metal wire cloth. This document applies to test sieves having aperture sizes from 125mm down to 20µm, in accordance with GB/T 6005-2008. 2 Normative references The following documents contain provisions which, through reference in this text, constitute indispensable provisions of this document. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 5329 Test sieves and test sieving vocabulary (GB/T 5329-2003, ISO 2395:1990, MOD) GB/T 6005-2008 Test sieves - Metal wire cloth, perforated metal plate and electroformed sheet - Nominal sizes of openings (ISO 565:1990, MOD) Note: There is no technical difference between the referenced content from GB/T 6005-2008 and that from ISO 565:1990. ISO 2591-1:1988 Test sieving - Part 1: Methods using test sieves of woven cloth and perforated metal plate 3 Terms and definitions For the purposes of this document, the terms and definitions given in GB/T 5329 and the following apply. 3.1 test sieve measuring instrument used for sieving Note: ISO/IEC Guide 99:2007 defines a "measuring instrument" as a device used for making measurements, alone or in conjunction with one or more supplementary devices.   4 Designation Test sieves of metal wire cloth shall be designated by the frame size, nominal aperture size and metal wire diameter (referred to as "wire diameter"). Example 1: A test sieve of metal wire cloth with a frame size of φ200mm×50mm, a nominal aperture size of 90mm and a wire diameter of 6.3mm shall be designated as: φ200×50—90/6.3 GB/T 6003.1-2022. Example 2: A test sieve of metal wire cloth with a frame size of φ200mm×50mm, a nominal aperture size of 900μm and a wire diameter of 500μm shall be designated as: φ200×50—0.9/0.5 GB/T 6003.1-2022.   5 Metal wire cloth 5.1 Technical requirements Aperture maximum permissible errors and wire diameters shall be as specified in Tables 1 and 2. Table 1 Maximum permissible errors of apertures and wire diameters (W≥1mm)
