29 Test sieves TEST SIEVES are used to measure particle size distribution, and the accuracy of eye opening is very important. Under stringent quality control, we meticulously choose materials and weave wire mesh using high-precision, specialized weaving looms. All finished wire meshes undergo a comprehensive inspection following the JIS Z8801-1 (Test sieves - Metal wire sieves) standards. Only those that meet the required standards are approved for shipment. It is also possible to issue a certification certificate and a data table at a separate cost. It is also possible to attach a calibration certificate from the Japan Quality Assurance Organization (JQA), which is certified as a calibration organization based on ISO/IEC 17025. 30 25 25 20 20 15 10 5 0 (nominal open 106 μm) Figures [-] 94.5 97.5 97.5 103.5 109.5 112.5 115.5 115.5 115.5 115.5 115.5 115.5 115.5 1115.5 2.5 2.6000 2.60 2.60 200 20 20 20 20 20.6.6.20 20 20 20 20 20 2020 20 4.6. b) Due to the small number of sieves to be measured, σ0 is not defined because it is not realistic. Note a) Nominal opening (38 μm or more) is based on Table 2 of ISO 565 (Main dimensions: R20/3, auxiliary dimensions: R40/3). Note a) Nominal opening is based on Tables 1 and Table 2 of ISO 565 (assistant dimensions: R20).
