This document specifies a method for the determination of the particle size distribution of coating powders by sieve analysis. Particle size distributions with a maximum of less than 100 ?? is determined by laser diffraction@ ISO 8130?13. This method is used especially for determining the oversize material or for the presence of contamination and can be used as a quality control procedure (??go??/??no go?? test) by checking the amount retained on a single sieve. The following particle sizes are typical for coating powders@ however the particle size can deviate depending on the application: -thin-film technology: 1 ?? to 63 ??; -electrostatic coating: 10 ?? to 200 ??; -fluidizing-bed method: 100 ?? and above. NOTE Sieves with a mesh size smaller than 32 ?? are not practical and are likely to become blind during use.
