IS 2405:2000 (Part 2) is the Indian Standard (BIS) for industrial sieves, part ii: perforated plates. This standard specifies the requirements for perforated plates used as industrial sieves. It details the acceptable materials, aperture shapes (round and square), hole arrangement patterns, and manufacturing tolerances necessary for industrial sizing and grading operations.

Key Differences
≠IS 2405 is from the year 2000, while its primary international counterparts (ISO 3310-1 and ASTM E11) have been updated more recently (2016 and 2020 respectively), incorporating more advanced inspection techniques and potentially tighter tolerances.
≠IS 2405:2000 allows for a wider range of wire materials, including galvanized or tinned mild steel, which is generally not specified in modern ISO or ASTM standards for precision test sieves due to corrosion and durability concerns.
≠Modern standards like ISO 3310-1 provide more detailed and stringent marking and traceability requirements, often mandating unique serial numbers for each sieve, which is not a mandatory requirement in IS 2405:2000.
≠The inspection and verification procedures in ISO 3310-1 and ASTM E11 are more statistically rigorous and detailed, specifying the number of apertures to be measured and the optical equipment to be used, compared to the more general guidance in IS 2405:2000.
Key Similarities
≈All standards are fundamentally based on the same geometric progression of nominal aperture sizes (based on Renard's R-series), ensuring compatibility and logical sequencing in sieve analysis across different systems.
≈The basic constructional principle of a test sieve, consisting of a taut woven wire cloth mounted on a rigid circular frame, is identical across all standards.
≈All standards specify the use of a plain square weave for most aperture sizes to ensure aperture stability and consistency, with twill weave permitted for very fine or heavy-duty applications.
≈The concept of defining tolerances for average aperture size, maximum individual aperture size, and wire diameter is a core and consistent feature in IS 2405 and its international equivalents.

What hole shapes are covered under this standard?+
The standard specifies dimensions and tolerances for both round and square perforations.
What is the recommended hole arrangement for round perforations?+
A 60-degree staggered arrangement is standard to maximize open area while maintaining structural integrity.
What materials are typically used to manufacture these sieve plates?+
Mild steel, stainless steel, and brass are most common, chosen based on the abrasiveness and corrosiveness of the material being sieved.
How does plate thickness affect the perforations?+
The thickness of the plate must be appropriately matched to the aperture size to allow clean punching and maintain rigidity without causing material blockage.
