GB/T 19628.2---2005
This standard is a modification of SO4783-2:1989&T "Guide to the combination of mesh size and wire diameter for industrial metal mesh and metal wire woven mesh - Preferred combination selection of metal wire woven mesh". This standard is the second part of the series of standards for industrial metal wire mesh and metal wire woven mesh. This series of standards will include: GB/T5330.1-2000 Guide to the combination of mesh size and wire diameter for industrial metal screens and other metal wire woven meshes - General rules:
G8/19628.2=2005 Guide to the combination of mesh size and wire diameter for industrial metal bag nets and metal wire woven meshes - Preferred combination selection of metal wire woven meshes; GF/T19628.3 Guide to the combination of mesh size and wire diameter for industrial metal mesh and metal wire woven mesh - Preferred combination selection of pre-bent or pressure-welded metal wire meshes. This standard is different from ISO4783-2:1989, for example, the table of material density is placed in Appendix A. Appendix A of this standard is an informative appendix.
This standard was proposed by the National Technical Committee for Standardization of Screen Screening and Particle Sorting Methods (CSBTS/TC168). This standard was drafted by the National Technical Committee for Standardization of Screen Screening and Particle Sorting Methods. The drafters of this standard are Yu Fang, Wu Guofei, and Huang Gang. This standard is interpreted by the Secretariat of the National Technical Committee for Standardization of Screen Screening and Particle Sorting Methods. 1 Scope
