Plastiques — Résines d'homopolymères et de copolymères de chlorure de vinyle — Détermination de la taille des particules par tamisage mécanique

ISO 22498:2005 specifies a method for the determination of the size distribution of particles of vinyl chloride homopolymer and copolymer resins by measuring the amounts retained on a selection of sieves having meshes of various aperture sizes.

The results can be expressed either in terms of the amount retained on the individual sieves or as the mean particle size for the whole test sample.
