GB/T 10613-2003
This standard is modified to adopt ISO7805-1:1984 "Industrial sieve plates Part 1: Plate thickness ≥ 3mm" (English version). The main changes are as follows:
-ISO7805-1 gives the limit deviation of sieve holes and hole spacing in the form of formulas, and gives examples in the form of appendixes, while this standard directly gives the values ​​in the form of Tables 1 and 2, and gives the formulas for the limit deviation of sieve plate hole spacing and sieve hole size in the form of Appendix A. This standard replaces GB/T10613-1989 "Circular and square hole sieve plates with plate thickness ≥ 3mm". Compared with GB/T10613-1989, the main changes of this standard are as follows: Added provisions on materials;
- Modified some contents of marking and packaging, and added simple packaging methods. Appendix A of this standard is a normative appendix.
This standard was proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Technical Committee for Standardization of Screen Screening and Particle Sorting Methods (CSBTS/TC168). This standard was drafted by the Mechanical Science Research Institute, and Hunan Yueyang Wujiang Machine Screen Co., Ltd. participated in the drafting. The drafters of this standard are Wu Guochuan, Wan Jun, Sun An, and Yu Fang. This standard is interpreted by the Secretariat of the National Technical Committee for Standardization of Screen Screening and Particle Sorting Methods. The previous versions of the standards replaced by this standard are: -GB/T10613—1989.
