ISO 8130-13 Coating Powders Particle Size Analysis by Laser Diffraction

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 8130-13 testing. This standard specifies a method for determining the equivalent spherical particle size distribution of coating powders by laser diffraction for particles in the 1 µm to 300 µm range.

There is a possibility that particle sizes of 300 µm will require the use of a different optical model.

This standard is specific to the measurement of coating powders and also draws attention to ISO 13320, which provides guidance on instrument qualification and particle size distribution.

Laser diffraction is not suitable for identifying large sized materials that can be verified by sieve analysis as described in ISO 8130‑1 or by dynamic image analysis as described in ISO 13322‑2.

A coating powder sample is analyzed by dynamic light scattering. Dust particles scatter light and their intensities are measured at various angles by a multi-array detector to obtain a scattering. The pattern is then converted into numerical values ​​using an appropriate optical model, and the mathematical procedure that gives the ratio of the total volume of particles for a discrete number of size classes that creates a volumetric particle size distribution.
