Alternative methods for particle size determination include: water sieving for powders; size measurement with magnification: microscopic counting; particle fall in a fluid without acceleration: settling; particle fall in a fluid with acceleration: cycloning; electromagnetic wave diffraction: turbidity; dielectric properties: Coulter counter. 5.1.2 Principle Measurement of particle size distribution by sieving for granular materials or laser diffraction for powders. 5.1.3 Particle size distribution for granular material The particle size distribution for granular material shall be determined in accordance with ISO 2591-1; see also ISO 2395 and ISO 565. 5.1.4 Particle size distribution for powders 5.1.4.1 General The laser diffraction method described applies to powders in suspension in a liquid or gaseous fluid as well as to aerosols or emulsions. Measurable particle sizes are between 0,5 µm and an upper limit linked to the optical configuration of the laser equipment used which can range up to 3 600 µm. The principle of the method and guidance on measurement are given in ISO 13320-1. 5.1.4.2 Reagents All reagents shall be of a recognized analytical grade and the water used shall conform to grade 3 in accordance with EN ISO 3696.
