Test Sieves - (TS-01)Test sieves is a common laboratory requirement. Sieves are used for sieving of chemical powders, medical powders, aggregate, sand soil and cement etc. These sieves are manufactured as per various standards like ISS, BSS, ASTM, DIN etc. Sieves are commonly used for gradation and particle size determination.
Sieves are selected to cover the entire range of particle sizes present in the test specimen. A nest of sieves having a bar(2) progression of the area of the sieve openings is recommended. The nest of sieves is assembled with the coarsest screen at the top and the finest at the bottom. Use micrometers or millimeters in denoting test sieve openings.

Mesh size is referring to the mesh number (a US measurement standard) and its relationship to the size of the openings in the mesh and thus the size of particles that can pass through these openings. Figuring out the mesh number is simple. All you do is count the number of openings in one linear inch of screen.
