Foreword

YS/T 438 "sandy alumina determination of physical performance" is divided into five sections. --- Part 1. Determination of particle size distribution by sieving; --- Part 2. Determination of the abrasion index; --- Part 3. Determination of angle of repose; --- Part 4. Determination of specific surface area; --- Part 5. Determination of α- alumina content of X- ray diffraction. This is Part 1. The partial replacement of YS/T 438.1-2001 "sandy alumina determination of physical performance screening method for the determination of particle size distribution." This part is YS/T 438.1-2001 revision compared with the YS/T 438.1-2001, the main changes are as follows. --- Increased precision; --- Increased quality assurance and control of the content; --- Analysis sieve set from the original five reduced to three; --- Drying temperature of the sample "300 ℃ ± 10 ℃" amended to "105 ℃ ± 5 ℃". This section drafted in accordance with GB/T 1.1-2009 given rules. The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized. This part mainly drafted by. Aluminum Corporation of China Guangxi Branch, Luoyang Xiangjiang Wanji Aluminum Co., Ltd. The main drafters of this section. Yang Yun screen, the more Liang Bin, Luo Xiangning, Zhang Feng flowers, Jiang Wei. This part of the standard replaces the previous editions are. --- YS/T 438.1-2001. Sandy alumina determination of physical performance Part 1. Determination of particle size distribution by sieving
