Overview - ISO 3310-2:2013 (Test sieves of perforated metal plate)
ISO 3310-2:2013 specifies the technical requirements and test methods for test sieves manufactured from perforated metal plate. It covers sieves with round holes (125 mm to 1 mm) and square holes (125 mm to 4 mm) in accordance with ISO 565. The standard ensures dimensional accuracy of sieve openings so that particle size analysis and sieving results are reproducible and traceable.
Key topics and technical requirements
- Scope and designation
- Nominal hole size (mm) and shape (round or square) define sieve designation.
- Hole size tolerances and pitch
- Tolerances on individual hole sizes and preferred pitches are specified (see Table 1). Pitches have a permissible range to allow practical manufacturability while maintaining sieving accuracy.
- Plate thickness and materials
- Preferred nominal thicknesses and permissible ranges are given (Table 2). Typical materials: plated steel or brass; purchasers can specify stainless steel.
- Hole arrangement and geometry
- Holes may be in straight or staggered rows; square-hole corners may have limited rounding. Sieves ≥4 mm require an unperforated margin; partial holes are not permitted.
- Inspection and test methods
- Mandatory tests include a visual inspection and measured verification of individual hole sizes and pitch. Measurement precision requirements (e.g., reading precision of 20 µm or 1/4 of the applicable tolerance) are specified.
- Documentation, certification and record keeping
- Manufacturers may supply a test sieve record card and certificates: compliance, inspection (average hole size), and calibration (detailed measurement results).
- Frames and marking
- Recommendations for frame sizes (200 mm typical), nesting, sealing to prevent sample loss, and required marking (nominal size/shape, material, standard reference, manufacturer, serial number).
Practical applications and who uses ISO 3310-2
- Particle size analysis and quality control in industries such as minerals, aggregates, pharmaceuticals, food, and chemicals.
- Testing and calibration laboratories that need traceable sieve specifications and calibration records.
- Sieve manufacturers and suppliers for production tolerances, documentation, and conformity certificates.
- Procurement and QA teams who require specified sieve performance for standard test methods.
Using ISO 3310-2 helps ensure consistent sieving performance, repeatable test results, and compliance with international best practice.
