Aggregate Test Sieves: Frame Sizes, Openings & Accessories
Choose Frame Diameter and Opening Size Separately
Test sieves separate aggregate samples into particle-size fractions. Frame diameter and mesh opening size are independent specifications: frame diameter describes the sieve's width, while opening size describes the mesh itself. Confirm both against your required method rather than treating the frame size as an indication of the opening.
Browse the listed diameter groups—3in, 6in, 8in, 10in, 12in and 18in diameter ASTM sieves—then select openings from the required gradation sequence.
Match Frame Height and Construction
Check full-height, half-height and intermediate-height options against the sieve-stack capacity of your shaker or screen. Height affects how many sieves fit in a stack, and frame material—brass or stainless steel—should suit the material being tested and your laboratory's care practices.
Verify the cloth material and any certification or inspection documentation offered for the selected sieves. Frame appearance does not establish opening accuracy, so rely on the manufacturer's specifications and documentation rather than visual comparison.
Consider Specialized Sieve Types
For washing applications, compare Deep Frame Wash Sieves. Where the procedure requires ISO-designated sieves, review the 200mm and 300mm diameter ISO test sieves; ISO and ASTM designations are not interchangeable, so confirm which system your method specifies.
For fine-particle work requiring tighter opening tolerances, compare ASTM Precision Electroformed Sieves, and for replaceable-mesh workflows, review two-part replaceable mesh sieves. Specialized sieves carry their own handling and verification requirements; confirm them before mixing sieve types in one stack.
Complete the Setup with Pans, Covers and Racks
Match pans and covers to the sieve diameter in use. The 8in Brass Sieve Pan with Drain and 12in Brass Sieve Pan with Drain support washing workflows, while stainless-steel versions are listed for the same diameters. Confirm diameter compatibility before ordering; a pan for one frame size does not fit another.
For storage, compare the Adjustable Bench Sieve Storage Rack, Wall-Mount Sieve Rack for 8in Sieves and Wall-Mount Rack for 12in Sieves. Sieve performance depends on mesh condition, so plan handling and storage to protect openings rather than stacking loose sieves.
Plan Verification and Cleaning
Where your quality system requires sieve verification, review the listed NIST Glass Beads for Sieves in the applicable size ranges. Follow the manufacturer's instructions and the governing procedure for verification intervals and documentation; calibration materials do not replace the required laboratory record-keeping.
Clean sieves with the appropriate sieve cleaning brushes for the mesh in use, or use an ultrasonic sieve cleaner where the sieve manufacturer approves it. Match cleaning methods to mesh fineness and frame construction rather than using one approach for all sieves, and inspect mesh condition before each use.
