The 8-inch (20 cm) Brass Test Sieve is designed for particle-size analysis, sieve analysis and laboratory material classification.
The product uses a polished brass frame and is available with fine wire mesh or coarse perforated-plate openings depending on the required aperture size.
Available coarse aperture sizes include 125, 106, 100, 90, 80, 75, 70, 63, 53, 50, 45, 40, 37.5, 31.5, 26.5, 25, 22.4, 20, 19, 16, 14, 13.2, 12.5, 11.2, 10, 9.5, 8, 6.7, 6.3, 5.6 and 4.75 mm.
Fine-mesh options are also available for smaller particle-size analysis requirements.
Used for aggregate testing, soil testing, cement and concrete analysis, powder classification, laboratory sieve analysis and construction-material quality control.

The current product information references IS 460, ASTM, BSS and ISO laboratory testing requirements. Exact sieve specification should be selected according to the required test method and aperture size.
It is used for particle-size analysis and separation of laboratory samples according to aperture size.
The listed brass sieve has a nominal diameter of approximately 8 inches or 20 cm.
Yes. The current product range includes fine wire-mesh sieves and coarse perforated-plate sieves.
Yes. The 8-inch configuration is intended for use with compatible manual or motorized sieve-shaker systems.

For reliable sieve specification, use the actual aperture opening together with the applicable test method or standard. Generic BSS, ASTM and ISS number crosswalks are not treated as universally interchangeable.
| Aperture (mm) | Aperture (µm) |
|---|---|
| 4.75 | 4750 |
| 2.36 | 2360 |
| 1.18 | 1180 |
| 0.600 | 600 |
| 0.425 | 425 |
| 0.300 | 300 |
| 0.150 | 150 |
| 0.075 | 75 |
See the full Mesh Size & Micron Guide, IS 460 Guide and ASTM E11 vs ISO 3310 before specifying a sieve for a formal laboratory method.
For an accurate quotation and the correct laboratory configuration, send the actual aperture and the test method or standard wherever possible. A mesh number alone can be ambiguous between designation systems.
