Sieve Verification, or certification, is the measurement and analysis of mesh openings and wire diameters in woven wire sieve cloth. A specified number of openings and wires are examined, and statistical calculations determine whether ASTM or ISO requirements have been met.

Test sieves are measuring devices used to determine the size and size distribution of particles in a material sample using wire mesh of different openings to separate particles of different sizes. Test sieves usually consist of wire mesh held in a frame. In most laboratory applications the frame is round and is made from stainless steel or brass.

Standard test sieves (Fig. 1) that conform to ASTM Specification E11 are a series of test sieves with intervals based on a fixed ratio of 4√2:1 between opening sizes (Table 1). The concept, pioneered by Peter Ritter von Rittinger of Austria in 1867, was first introduced in the United States in 1910 and has since achieved worldwide use.

Calibration Grade sieves should be used in applications where a very high degree of accuracy is necessary. These sieves are best when you need to verify that your working sieves meet ASTM E11 requirements. Importance of ongoing verification. Ongoing verification of a used sieve is just as important as starting with a reliable new one.

The ASTM D 422 sieve analysis is a widely accepted standard for identifying particle size in soils. It also allows for other methods like the sedimentation standard D7928 and the laser diffraction method. These methods differ in accuracy, range, and cost. Understanding their differences helps choose the best method for a project's specific needs.
