TEST SIEVES
W.S. Tyler developed the first Test Sieve products and standards that we know today. While a Test Sieve may appear to be very simple, it is actually a very valuable instrument used for Quality Control every day. Sieving remains a very cost efficient method of measuring particles, producing consistent, repeatable results.
Standard Test Sieve diameters include 3", 8", 12", 200 mm, and 300 mm. Special application products are available in 6", 10", and 18" diameters and include air jet and wet test designs. All W.S. Tyler Test Sieves are fabricated in brass and durable stainless steel. Our premium quality testing sieve cloth, woven by Haver & Boecker, is produced to the very tight tolerances, providing consistent repeatable analysis. Standard openings per international specifications range from 5" (125 mm) down to 20 um (micron). Contact Us
Repeatable from laboratory to laboratory, state to state, country to country, is a long term goal of W.S. Tyler providing a long term benefit to quality control managers worldwide.
W.S. Tyler Test Sieves conform to the current ASTM E11-09 and ISO 565, 3310-1 specifications. The products detailed in TABLE 1 below are manufactured in Mentor, Ohio USA.
Test sieving has been used for particle measurement for generations in the Agricultural,
Bio-Industry, Chemical, Cosmetics, General Industrial, Fertilizer, Foods, Minerals,
Pharmaceuticals, Plastics and Metal Products industries.
Each W.S. Tyler Test Sieve is serialized and supplied with supporting documentation.
