GB/T 13220-1991
ActiveDetermination of particle size distribution of fine powder--Method of sieve classfication with sonic wave
细粉末粒度分布的测定 声波筛分法
Application Summary AI generated
This standard specifies a method for determining the particle size distribution of fine powders using sonic wave sieve classification. It is applied in metallurgy and materials testing to analyze powders finer than 45 micrometers, where conventional sieving is ineffective due to particle agglomeration or mesh blinding. The method is used for quality control in industries processing metal powders, ceramics, or other fine particulate materials.
