Certification and Testing Services
W.S. Tyler offers premium test sieve analysis and calibration services to ensure the performance of test sieves for quality control programs. Our services are applicable for both new and in-use test sieves.
The Primary Standards that govern Test Sieves are ASTM E 11-13 and ISO 3310-1. Both W.S. Tyler and its parent organization, Haver & Boecker, Germany, are very active on the committees that write and oversee the Standards. By contributing our many years of expertise to the various committees, the marketplace can rely on the Standards to be valuable and practical to the product user
