What is BS EN ISO 8130-1 on coating powders about?
BS EN ISO 8130-1 is the first part of the BS EN 8130 multi-series on coating powders. BS EN 8130-1 specifies a method to find out the particle size distribution of coating powders, by sieve analysis. Particle size distributions with fewer than 100 μm are determined by laser diffraction. This method 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 μm to 63 μm Electrostatic coating: 10 μm to 200 μm Fluidizing-bed method: 100 μm and above
NOTE Sieves with a mesh size smaller than 32 μm are not practical and are likely to become blind during use.
