Sieve-Testing Standards, Certification, and Calibration

Sep 26, 2008· A way to determine if changes have occurred is to compare the sieve’s performance against a known standard. This is sieve calibration. In addition, in operations with tight particle-size specifications, calibration of new test sieves is performed to establish a performance baseline for the sieve.

Mid-point sieves are certified that the openings fall in the middle of the ASTM E-11-95 specification. Mid-point sieves provide a solid foundation for a dependable sieve calibration system. Although not recommended, a new set of calibrated sieves could be used. The sieves from a master set should only be used to calibrate working sieves.
