Some standard content:
National Standard of the People's Republic of China Industrial woven metal wire cloth (square openning series) UDC 621, 928, 2 GB5330—85 This standard is used for the screening of solid particles, the filtration of liquids and gases and other industrial purposes. This standard refers to the international standard IS04783/2·-1981≤1 Industrial screen and metal woven screen cloth, mesh size and wire diameter selection guide", mesh base size 16.0~0.025mm. 1 Weaving type, model and specification 1.1 Weaving type It is divided into plain weave (Figure 1) and twill weave (Figure 2). Figure 1 Plain weave Issued by the National Bureau of Standards on August 31, 1985 Implemented on April 1, 1986 1.2 Model 1.3 Specification GB5330-85 Figure 2 Twill weave Screen (net) Accuracy level Square hole (square) T Industry () Indicated by mesh base and wire diameter (see Table 1). 1.4 Accuracy level Grade 1 accuracy Grade 2 accuracy - Grade 3 accuracy - 1.5 Marking High precision Higher quality accuracy: General accuracy, Indicated by model, specification, weaving type and number of this standard. Example: The basic mesh size is 1.0mm, the wire diameter is .355mm, and the 1st level precision gold-reduced wire plain weave square hole screen for T industry is marked as: GFIW1.00/0.355 (-4 mm) GB5330—85 The basic mesh size is 0.063mm, the wire diameter is 0.0.45mm, and the 2nd level precision metal wire twill weave square hole screen for T industry is marked as: GF2W0.063/0.045 (twill) 2 Technical requirements GB 5330—85 GB5330—85 21 The combination of the basic mesh size W, the mesh arithmetic mean size deviation, the maximum mesh size deviation range, and the wire diameter d shall comply with the requirements of Table 1. 2.2 According to the special needs of the particle size of natural materials (such as grain, oil, etc.), the specifications in Table 2 may be selected. 2.3 The basic size and limit deviation of the metal wire diameter shall comply with the provisions of Table 3. 2.4 The number of large mesh holes allowed: the accuracy of level 1 shall not exceed 6%, the accuracy of level 2 shall not exceed 9%, and the accuracy of level 3 shall not exceed 112%.
