Test Sieve Size Chart in mm, Microns and Mesh
Use this test sieve size chart to compare nominal sieve apertures in millimetres (mm) and microns (µm), along with legacy BSS mesh references and ASTM mesh references. Mesh numbers may differ between standards, so confirm the nominal aperture and applicable test standard before selecting a laboratory test sieve.

Brass vs Stainless-Steel Test Sieves
| Selection Factor | Brass Frame | Stainless-Steel Frame |
|---|---|---|
| Typical Use | General dry laboratory sieving | Frequent use and cleaning-intensive applications |
| Frame Material | Brass | Stainless steel |
| Wire Cloth | Phosphor bronze or specified mesh | Stainless-steel wire cloth |
| Selection Note | Confirm chemical compatibility, cleaning method, aperture, diameter and applicable test standard before ordering. | |
How to Select the Correct Laboratory Test Sieve
- Standard: specify IS 460, ASTM E11, ISO 3310 or the standard required by your test method.
- Aperture: order by nominal opening in millimetres or micrometres; do not rely only on mesh number.
- Diameter and height: match the sieve frame to the sieve shaker and required sample volume.
- Material: select brass, G.I. or stainless steel according to corrosion resistance and cleaning needs.
- Sieve medium: choose woven wire cloth or perforated plate according to aperture size and application.
- Documentation: state whether a conformity or calibration document is required.
Cleaning, Inspection and Storage
After each test, clear out retained material using a method suited to the mesh and sample. Don't force hard tools through fine wire cloth. Check the frame, mesh tension and apertures for damage, then store clean, dry sieves separately to prevent distortion. Verification frequency should follow the laboratory quality system and applicable test method.
For an independent standards reference, see ASTM E11 for woven wire test sieve cloth and test sieves.

Frequently Asked Questions:
Test sieve standards specify requirements for apertures, construction and permissible tolerances. Select the standard required by your testing method or purchase specification, such as IS 460, ASTM E11 or the relevant part of ISO 3310. When using a legacy BSS mesh reference, confirm the nominal aperture and applicable standard before ordering.
For an accurate quotation, provide the required standard, nominal aperture or mesh size, sieve diameter, frame material, sample type and whether you need a lid, receiver or supporting documentation.
Sieve analysis measures the particle size distribution of a sample. Quality-control teams compare the results with specified grading or acceptance limits. Reliable results depend on representative sampling, suitable sieves and following the applicable test method.
