ISO Test Sieves
ISO test sieves
Gilson's 200mm and 300mm diameter ISO test sieves meet ISO 565 and 3310-1 specifications for Compliance Sieves. Gilson offers all ISO 565 Mesh Sizes. Every ISO sieve is fitted with a rubber O-ring for a dust-free seal when nested in a sieve stack. Many ISO opening sizes and tolerances are equivalent to ASTM E11 sizes.
Sample volume and particle size determine proper frame diameter and height. Material is processed more efficiently and accurately on a sieve with more surface area, and blinding is reduced. The thickness of a specimen fraction on the mesh of a sieve should be no more than a couple of particles or layers deep. Frame height must permit proper agitation of the specimen, allowing larger particles enough room to reorient to the mesh surface.
