Recommended for general established sieving programs, including aggregates, and use with rotating tapping sieve shakers
Certified sieves Top quality construction and performance characteristics, for use with start up sieving applications and educational use. Recommended for use with vibratory sieve shakers
30% reduced ASTM E 11 Tolorences. For more exacting sieving applications, where electroformed accuracy is not neccessary. Recommended for use as a master stack with performance test sieve calibration programs (ASTM E 2427)
Manufactured in accordance with ASTM E 161, where ASTM E 11 Tolerances are too great. Accuracies of +/- 2 microns are achieved. May require use of special sifters for below 20 micron sieving applications
