"GB/T 21782.1-2008 Powder coatings Part 1: Determination of Particle size distribution by sieving method" stipulates the method of determining powder coatings Particle size distribution by sieving method. This method is suitable for powder coatings with particle size range of 32 μm to 300 μm. The powder is sieved by standard sieve to calculate the mass percentage of each particle size segment, so as to obtain Particle size distribution. Standard equivalence adopts ISO 8130-1:1992, which is centralized by the National Standardization Administration of China and implemented by the National Technical Committee for Standardization of Hazardous Chemicals Management. It was issued on May 12, 2008 and implemented on September 1, 2008.
