Foreword
This Document was drafted as per the rules specified in GB/T 1.1-2020 Directives for Standardization – Part 1: Rules for the Structure and Drafting of Standardizing Documents. This Document is Part 1 of GB/T 6003 Test Sieves – Technical Requirements and Testing. GB/T 6003 has published the following parts:
--- Part 1: Test Sieves of Metal Wire Cloth;
--- Part 2: Test Sieves of Perforated Metal Plate;
--- Part 3: Test Sieves of Electroformed Sheets.
This Document replaced GB/T 6003.1-2012 Test Sieves – Technical Requirements and Testing – Part 1: Test Sieves of Metal Wire Cloth. Compared with GB/T 6003.1-2012, the major technical changes of this Document are as follows besides the structural adjustments and editorial modifications:
--- Delete the relevant provisions of “unit” (see 4.2 of 2012 Edition); --- Change the relevant provisions of aperture size deviation, aperture size limit deviation, average aperture size deviation and maximum standard deviation (see 5.1.1 of this Edition; 5.1.1 of 2012 Edition);
--- Increase the description and calculation formula of the maximum standard deviation σ0 (see 5.1.1.4 of this Edition);
--- Change the expression of the predicted standard deviation value; and change the "predicted standard deviation value" into "the estimated standard deviation value" (see 5.1.1.4 of this Edition; 5.1.1.4 of 2012 Edition);
--- Delete the recommended materials (see 5.1.2.4 of 2012 Edition);
--- Change the general requirements (see 5.2.1 of this Edition; 5.2.1 of 2012 Edition); --- Change the expression of the detection of the aperture size limit deviation X (see 5.2.3 of this Edition; 5.2.3 of 2012 Edition);
--- Change the relevant provisions of the sampling instructions in the measurement of the average aperture size 𝑤ഥ , the average aperture size deviation Y, the maximum standard deviation σ0 and the wire diameter d (see 5.2.4 of this Edition; 5.2.4 of 2012 Edition); --- Change the relevant provisions of the test sieve frame (see Clause 6 of this Edition; Clause 6 of 2012 Edition);
--- Change the relevant provisions on the identification of test sieves (see Clause 7 of this Edition; Clause 8 of 2012 Edition).
This Document modified and adopted ISO 3310-1:2016 Test Sieves – Technical Requirements and Testing – Part 1: Test Sieves of Metal Wire Cloth.
Compared with ISO 3310-1:2016, this Document made the following structural adjustments: --- 5.2.1 corresponds to 5.2 overview in ISO 3310-1:2016; and 5.2.2~5.2.4 corresponds to 5.2 "Test 1" to "Test 3" in ISO 3310-1:2016.
There are technical differences between this Document and ISO 3310-1:2016; and the clauses involved in these differences have been marked by a vertical single line (│) in the outer margin of the Document. The technical differences and their causes are as follows: --- Replace ISO 2395:1990 with the normative reference GB/T 5329; and revise the degree of consistency between the two documents to adapt to the technical conditions of China; --- Replace ISO 565:1990 with the normative reference GB/T 6005-2008; and revise the degree of consistency between the two documents to adapt to the technical conditions of China;
--- Delete 4.2; merge relevant content with 5.1; and merge the same description content; --- Add examples of test sieve markings, standardizing product identification. Please note some contents of this Document may involve patents. The issuing agency of this Document shall not assume the responsibility to identify these patents. This Document was proposed by and under the jurisdiction of National Technical Committee on Particle Characterization and Sorting and Screen of Standardization Administration of China (SAC/TC 168).

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
< Particle size analysis> 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 Markings
4.1 The marking of test sieve of metal wire cloth consists of sieve frame size, basic aperture size, and metal wire diameter (referred to as “wire diameter”).
EXAMPLE 1:
The marking of test sieve of metal wire cloth with sieve frame size of ϕ200mm × 50mm, basic aperture size of 90mm and metal wire diameter of 6.3mm is as follows: ϕ200mm × 50mm-90/6.3 GB/T 6003.1- 2022.
EXAMPLE 2:
The marking of test sieve of metal wire cloth with sieve frame size of ϕ200mm × 50mm, basic aperture size of 900μm, and metal wire diameter of 500μm is as follows: ϕ200mm × 50mm-0.9/0.5 GB/T 6003.1- 2022.
