Comprehensive information on the CENTERLINE® measurement system is offered in a two-page color brochure. The brochure explains that current ASTM E-11 specification limits of test sieves may be too broad for many users’ particular applications. The brochure explains all steps and verification procedures involved in the CENTERLINE® measurement system, which was developed to verify exactly how a sieve compares to ASTM E-11 specifications. The process includes image analysis of opening sizes and wire diameters traceable to the National Institute of Standards and Technology (NIST). All sieves are serialized for accurate identification.
