ISO 3310-2 Perforated Plate Test Sieve is used for sizing coarse aggregates, ores, fertilizer granules and pellets with round- or square-hole perforated plates whose holes are certified to ISO 3310-2. ISO 3310-2 is the reference cited for it on drawings, datasheets and purchase orders.
What ISO 3310-2 Means for ISO 3310-2 Perforated Plate Test Sieve
The dimensions in the table below are supplied to suit ISO 3310-2. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
ISO 3310-2 Perforated Plate Test Sieve Dimensions
| Hole diameter (mm) | Frame diameter (mm) | Frame height (mm) | Pitch (mm) | Thickness (mm) | Hole shape |
|---|---|---|---|---|---|
| 4.0 | 300 | 75 | 5.5 | 1.0 | Round |
| 8.0 | 300 | 75 | 10.0 | 1.5 | Round |

Specifying ISO 3310-2 Perforated Plate Test Sieve Beyond the Standard
- Hole shape: Round or square holes as the test method specifies — results differ between them.
- Frame size: 300 mm for routine coarse work; 450 mm for very coarse material.
- Plate thickness: 1–2 mm; thicker plates resist denting by heavy stones.
When ISO 3310-2 Perforated Plate Test Sieve Is Not the Right Choice
Not for fine powders below about 1 mm; woven-wire test sieves are used there.
