This standard specifies the technical requirements and corresponding test methods for metal wire woven mesh test sieves. This standard applies to test sieves with mesh sizes ranging from 20μm to 125mm in GB/T 6005-1997.

GB/T 6003.1—1997
This standard is equivalent to IS03310-1:1990 Test sieves-Technical requirements and test sieves.
Part 1: Metal wire mesh test
This standard is a revision of the original GB6003-85 "Test sieves" and GB6004-856 "Metal wire woven square hole mesh for test sieves". The new national standard has the following changes in the main technical content: 1) In the test method, GB6003-8 focuses more on the requirements for test equipment. This standard focuses on the specific method of the test and the judgment of the results.
2) Compared with the international standard, this standard adds the provisions for the marking of the test sieve. This standard will be in line with GB6003B5 and GB6004-85 from the date of entry into force. This standard is proposed by the Ministry of Machinery Industry of the People's Republic of China. This standard is under the jurisdiction of the National Sieve Screening Standardization Technical Committee. This standard was drafted by: State-owned No. 540 Machinery Science Research Institute of the Ministry of Machinery Industry, State-owned No. 9699 Factory. The main drafters of this standard are: Deng Qian, Song Ruxuan, Song Xiupo: GB/T 6003. 1
ISO Foreword
ISO (International Organization for Standardization) is a worldwide joint organization composed of national standard bodies (ISO) of various member countries. The formulation of international standards is carried out through ISO technical committees. Each member country has the right to participate in the committee if it is interested in the project carried out by a technical committee. Governmental and non-governmental international organizations related to ISO may also participate in this work. The ISO has a close relationship with the International Electrotechnical Commission (IF) in the Department of Electrotechnical Standardization. The international standard draft adopted by the technical committee is circulated to all member countries for voting. The formal publication of international standards requires at least 5% of the voting fees of the member countries.
International Standard ISO 3310.1 was prepared by the ISO/TC24 Technical Committee on Screens, Sieving and Other Methods of Sorting. The third edition of this standard replaces the second edition (IS(3310-1:1982) and constitutes the content of the technical revision. Under the general title of "Test sieves - Technical requirements and inspection", ISO 3310 consists of the following parts: Part 1: Woven wire mesh test sieves Part 2: Perforated metal plate test sieves Part 3: Electroformed sheet test sieves (Annex A in ISO 3311 is for reference only). 1 Scope

4.1 Marking method
Screen size should be marked first, followed by the basic size of the mesh (see Table 1 and Table 2) and the preferred size of the wire diameter. The two are separated by a slash, and the unit is plus m; leave one space, and finally mark the national standard. 4.2 Marking example
The standard size of the sieve is 00×50mm, the basic size of the mesh is 90mm, and the wire diameter is 6.3mm. The marking of the wire woven mesh test sieve is:
$200X50—90/6.3GH/T6003.1—1997. The sieve frame size is 00×50mm, the basic size of the mesh is 900um. The wire diameter is 500um. The marking of the wire woven mesh test sieve is:

5.1 Technical requirements
The mesh tolerance and wire diameter shall be as specified in Table 1 and Table 2. 5.1.1 Mesh tolerance
5.1.1.1 The mesh tolerances X, Y, Z given in Table 1 and Table 2 require that the mesh size be measured on the mesh center line in the warp and weft directions (see Figure 1).

The mesh size shall not be larger than X:
The unit of X and w is μm. 5.7.1.3 The deviation range of the average mesh size from the basic size shall not exceed Y:sae. The units of Y and are um. The wire diameter is allowed to be selected within a range. 5.1.1.4 The number of meshes with a mesh size between 1 + X and 12 shall not exceed 2% of the total number of meshes. If the test sieve has less than 50 meshes, the number of meshes with a mesh size between 2 + X and 2e + 2 shall not exceed 3. 5.1.2 Metal wires 5.1.2.1 The wire diameters given in Tables 1 and 2 are applicable to the wire mesh used for the test sieve. 5.1.2.2 The wire point diameters given in Column 7 of Tables 1 and 2 shall be used preferentially. 5.1.2.3 The wire diameters of the warp and weft on the test sieve shall be of the same specification. 5.1.2.4 Recommended materials: austenitic stainless steel, bronze, brass. 5.2 Test method
In order to comply with the provisions of 5.1, any mesh of the wire mesh should be able to be tested. (9)
（3）
For test sieves with no more than 20 mesh holes, all mesh holes should be checked; for test sieves with more than 20 mesh holes, the following steps should be followed:
a) Observe the overall appearance of the screen:
h) Carefully check the individual mesh holes:
c) Measure the mesh size to see if it complies with the tolerances specified in Tables 1 and 2. In the methods described in 5.2.2, 5.2.3 and 5.2.4, the reading accuracy of the equipment used to measure the mesh size should be at least 2.5um, or 1/10 of the medium tolerance (2) of the basic size of the measured mesh hole in GB/T6003.1-1997
, whichever is greater. 5. 2.1. Inspection of the overall appearance of the metal wire mesh. Observe the wire mesh against a uniform lighting background. If obvious defects are found in the uniform appearance of the mesh, such as weaving defects, folds and impurities, the mesh is judged as unqualified. 5. 2.2 Inspection of mesh tolerance X
Inspect the appearance of all mesh holes, check the mesh holes that are too large and then measure them. Meshes with mesh size (w) deviations exceeding the mean value of 1 can be identified with an inner eye. At the same time, the unevenness caused by the arrangement and weaving of the mesh can be checked, that is, mesh distortion.
If any oversized holes are found to exceed the maximum allowable deviation X, the mesh is judged as unqualified. 5.2.3 Determination of meshes exceeding \w + Z\ Count the number of meshes with mesh widths within the range of "ze + \ and "+ X" (see 5.1.1) or determine their proportion at a representative sample site. If the number or the determined mesh proportion is greater than the provisions in 5.1.1.4, the net is judged to be unqualified. 5.2.4 Measurement of average mesh size and average wire diameter After the sieve is qualified by the methods of 5.2.1 to 5.2.3, the average mesh size and wire diameter shall be measured at the sample site. The method is as follows:
Measure the average mesh size on at least 10 meshes. If feasible, collect at least two sample sites on the wire mesh and measure in the warp and weft directions. If the average mesh size and the determined wire diameter are If the wire diameter does not meet the requirements given in Table 1 and Table 2 respectively, the sieve tree shall be judged as unqualified. 6 Test sieve frame
A round sieve frame with a diameter of 200mm can be used as much as possible: in the case of very fine test sieves and very little material to be screened, a smaller one can be used. For test sieves with larger mesh sizes, a 300mm round sieve frame or a force screen frame can be used. For test sieves with mesh sizes greater than 25mm and a large amount of material to be screened, a larger sieve can be used. The shape and size of the test sieve frame have no effect on the results of the screening operation. The size of the 30umm test sieve frame can exceed about 15mm. The diameter or length of the effective screening area should be within the range specified in Table 3 (see Figure 2):
, the size is determined by the manufacturer or agreed by both parties. Table 3

The sieve frame should be flat and smooth, and can be easily integrated with other sieves, covers, receiving trays and other sets of the same basic size as the sieve cabinet. The connection between the wire mesh and the sieve can prevent the leakage of the material to be screened. 8 Marking of test sieve
A clear metal nameplate should be fixed on the sieve. The nameplate should contain the following contents: a) The original size of the mesh and wire diameter
b) Execution standard:
( ) Materials of wire and sieve frame:
d) Name and logo of the manufacturer
