Product Overview
The CISA 200 mm Ø x 50 mm H test sieve is the most widely used sieve size in the CISA range, referenced by ISO, AFNOR, ASTM, BS, DIN, and UNE standards. It is available in five configurations to cover a broad range of particle analysis applications: wire mesh (configuration 200.1), square-hole perforated plate (200.2), round-hole perforated plate (200.3), elongated-hole perforated plate (200.4), and electroformed plate (200.5). The mirror-polished AISI-304 frame is suitable for wet sieving. Each sieve is laser-marked with a serial number and supplied with a certificate of compliance according to 2.1 EN 10204.
Key Features
- Five configurations: wire mesh, square perforated, round perforated, elongated holes, electroformed plate
- Wire mesh (200.1) compliant with ISO 3310.1 and ASTM E-11-2013; openings from 20 µm to 125 mm
- Perforated plate (200.2 and 200.3) compliant with ISO 3310.2 and ASTM E-323-2011
- Elongated holes (200.4) compliant with ISO 5223; designed for grain and cereal industry
- Electroformed plate (200.5) compliant with ISO 3310.3 and ASTM E-161; tolerance ±2%
- Mirror-polished frame; suitable for wet sieving
- Laser-marked serial number for individual traceability
- Frame material: AISI-304 stainless steel (AISI-316 frame available as option)
- Perforated plates not perforated in the area in contact with the frame, preventing partial holes
- Standard EN 933-2 recommends square perforated plates (ISO 3310.2) for openings of 4 mm and above

Available Configurations — 200 mm x 50 mm
| Code | Configuration | Applicable standard(s) | Opening range (wire mesh / plate) |
|---|---|---|---|
| 200.1 | Wire mesh sieves | ISO 3310.1 / ASTM E-11-2013 | 20 µm to 125 mm |
| 200.2 | Perforated plate — square holes | ISO 3310.2 / ASTM E-323-2011 | 4.00 mm to 125 mm |
| 200.3 | Perforated plate — round holes | ISO 3310.2 | 0.50 mm Ø to 50.00 mm Ø (standardised); additional non-standardised sizes available |
| 200.4 | Perforated plate — elongated holes | ISO 5223 | 1.00 x 20 mm to 6.00 x 30 mm; and electroformed 5 µm–500 µm |
| 200.5 | Electroformed plate — square holes | ISO 3310.3 / ASTM E-161 | 5 µm to 500 µm; tolerance ±2% |
Configuration 200.3 note: Sieves with perforations of 0.50 mm Ø, 1.00 mm Ø, 1.80 mm Ø, 4.00 mm Ø, and 4.50 mm Ø are used for testing rapeseed, rice, soybean, and other cereals.
Configuration 200.4 note: Elongated-hole sieves are constructed entirely of AISI-304 stainless steel. Primary application: grain and cereal industry.
Configuration 200.5 note: Electroformed sieves have tolerances two to ten times smaller than wire mesh, depending on opening size. Due to higher cost, their use is limited to applications requiring precision beyond wire mesh capability. Each sieve is supplied with a certificate of conformity.
