Full Description

This part of ISO 13317 describes a method using a pipette to determine particle size distribution, typically in the size range 1 m to 100 m, by gravitational sedimentation in a liquid.

The method of determining the particle size distribution described in this part of ISO 13317 is applicable to powders which can be dispersed in liquids or powders which are present in slurry form. The method is applicable to powders made up of particles having the same density and of comparable shape. Particles should not undergo any chemical or physical change in the suspension liquid. It is necessary that the particles have a density higher than that of the liquid.
