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.

Sheet - Nominal Sizes of Openings (ISO 565.1990, MOD)
3 Terms and Definitions
For the purposes of this Document, the terms and definitions given in GB/T 5329 and the
following apply.
< Particle size analysis> measuring instrument used for sieving.
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”).
5 Metal Wire Cloth
The aperture size deviation and metal wire diameter shall comply with the provisions of Tables
1 and 2.
View the wire cloth against a uniformly illuminated background. If obvious deviations from
uniformity of appearance are found, for example, weaving defects, creases and wrinkles, the
sieve is unacceptable.
The manufacturer may provide, at the specific request of the purchaser, a test sieve inspection
certificate stating the values for the average aperture size, separately in both the warp and weft
direction of the wire cloth; the minimum number of the measured aperture can refer to Table 4,
Column 2.
6 Test Sieve Frames
It is recommended that the 200 mm round metal frame be used as far as possible, especially for
metal wire cloth of basic aperture size up to 4 mm.
Smaller or larger frames may be appropriate for smaller or larger quantities of material to be
sieved.
7 Marking of Test Sieves
The test sieve shall be provided with fix and clear nameplate stating the following contents.
