W.S. Tyler™ 12-inch diameter Test Sieves conform to the current ASTM E11-09 standard.
Each sieve has a serial number and is supplied with a Certificate of Compliance.
Optional NIST traceable certifications are available, including statistics information on opening sizes and wire diameters.
A Sieve Shaker is usually required to provide a repeatable and uniform motion to ensure reproducible results. When fine mesh sieves are involved, hand sieving is not possible.
Sieve Analysis as a standard process in the analytical laboratory or in the food and environmental laboratory works perfectly only if the particles are removed from the sieve to the last grain. For efficient and safe cleaning of test sieves, the use of an ultrasonic cleaner is recommended.
