IS 10483:1983 is the Indian Standard (BIS) for code for designating perforations of industrial plate sieves (identical with iso/dis 7806). This standard establishes a uniform code for designating the perforations in industrial plate sieves. It provides a system for specifying the shape (round, square, slotted) and size of the openings to ensure consistency in manufacturing and procurement.
Code for designating perforations of industrial plate sieves (identical with ISO/DIS 7806)

Status
Current
Usage level
Specialized
Domain
Materials Science — Sieves, Sieving and Other Sizing Methods
! This code is solely for the designation (naming convention) of perforations. It does not cover material specifications, manufacturing tolerances, or testing procedures, which are found in other standards like the IS 460 series.
! As this standard is identical to ISO 7806, it facilitates the specification and procurement of industrial sieves in international trade.
! The designation applies to the nominal size of the perforation, not the effective screening area or other performance characteristics.

Key Differences
≠IS 10483 is a code for designation only, whereas modern standards like ISO 3310-2 are comprehensive specifications that include manufacturing tolerances, material requirements, and testing procedures.
≠The Indian standard is based on a withdrawn ISO draft from the early 1980s (ISO/DIS 7806) and has not been updated, while the international standard has evolved into ISO 3310-2:2013.
≠IS 10483 does not specify mandatory plate thickness, tolerances on aperture size, or arrangement of holes (e.g., 60° stagger for round holes), which are all defined in ISO 3310-2.
≠The scope of IS 10483 refers to 'industrial plate sieves', a broad term, while ISO 3310-2 specifically addresses 'test sieves', implying a higher degree of precision and quality control.
Key Similarities
≈The fundamental principle of designating perforations by shape (Round, Square) and a nominal size is consistent across IS 10483 and its international counterparts.
≈Both IS 10483 and the original ISO 7806 use a similar coding structure: Shape Code - Aperture Size / Pitch (e.g., R 5.00 / 8.00).
≈The primary hole shapes covered, Round (R) and Square (S), are the same in both the Indian and international standards for perforated plate sieves.
≈The core purpose of all these standards is to provide a clear and unambiguous system for describing perforated plates to avoid misinterpretation in procurement and manufacturing.

Arrangement of Round Holes
Not explicitly defined, though pitch 'p' is part of the designation.
Holes shall be on a triangular pitch (staggered at 60°).
ISO 3310-2:2013
Arrangement of Square Holes
Not explicitly defined, though pitch 'p' is part of the designation.
Holes shall be on a square pitch (parallel to the sides of the sieve).

How do I specify a 10 mm round hole sieve according to this code?+
The designation would be 'R 10', where 'R' stands for a round perforation and '10' is the nominal diameter in millimetres.
What does the symbol 'L' mean in a sieve designation?+
'L' designates a slotted (oblong) perforation. The designation would also include the width and length, for example 'L 8 x 30'.
Does this standard apply to wire cloth or wire mesh sieves?+
No, this code is specifically for industrial plate sieves (perforated plate). Wire mesh sieves are covered by separate standards, such as the IS 460 series.
