Foreword
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents"
Drafting.
This document replaces GB/T 5758-2001 "Method for determination of particle size, effective particle size and uniformity coefficient of ion exchange resin" and is consistent with
Compared with GB/T 5758-2001, in addition to structural adjustments and editorial changes, the main technical changes are as follows.
---Added the definition, testing and calculation methods of average particle size (see 3.5, 4.4.6 and 4.6.4);
---Changed the screening method to Method 1 (see Chapter 4, Chapter 4 of the.2001 edition);
---Changed the schematic diagram of the pretreatment column and the schematic diagram of the screening funnel (see Figure 1, Figure 1 of the.2001 version);
--- Added method two, laser diffraction method (see Chapter 5);
---Changed Appendix A to the calculation of particle size (sieving method) results.
