GB/T 4195-1984 is a test standard for the particle size distribution of tungsten and molybdenum powders. The standard adopts the sedimentation Balance method, which is suitable for the determination of the particle size distribution of tungsten and molybdenum powders. By clarifying the experimental principles, equipment, operation procedures, etc., the relevant personnel are instructed in detail how to use the sedimentation Balance to detect the particle size distribution of tungsten and molybdenum powders, which provides a unified standard method for accurately evaluating the particle size characteristics of tungsten and molybdenum powders at that time.
