IS 3042:1965 is the Indian Standard (BIS) for single faced sluice gates (200 to 1200 mm size). This standard lays down the requirements for materials, design, manufacture, dimensions, and testing of single-faced cast iron sluice gates (200 mm to 1200 mm size) used for water supply, sewerage, and drainage systems.

BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
Practical Notes
! Always specify whether the gate will be subjected to 'seating' or 'unseating' hydrostatic head, as this heavily influences the required wedge arrangement.
! Ensure perfect alignment of the guide frames and spindle during installation to prevent jamming and premature wear of the bronze sealing faces.
! For sewage applications, periodic operation and greasing of the spindle are mandatory to prevent operational failures.
Covers cast iron slide gates for water control, overlapping on material, application, and basic design.

Key Differences
≠IS 3042 specifies outdated material grades (e.g., Cast Iron FG 200 to IS:210). Modern standards like AWWA C560 reference current ASTM grades (e.g., ASTM A126 Class B) and provide for modern materials like ductile iron and stainless steel.
≠IS 3042 only states gates 'should be reasonably water-tight'. Modern standards like AWWA C560 and DIN 19569-4 provide specific, quantifiable maximum leakage rates (e.g., L/min per meter of sealed perimeter).
≠The Indian standard specifies a basic, prescriptive coating system (red lead primer and bituminous paint). International standards specify a range of high-performance, tested coating systems like fusion-bonded epoxy, often requiring certification for potable water contact (e.g., NSF/ANSI 61).
≠IS 3042 focuses on manual operation. AWWA C560 is specifically for 'Actuator-Operated' gates and includes detailed requirements for electric, hydraulic, and pneumatic actuators, their sizing, controls, and performance testing.
Key Similarities
≈All standards cover the same fundamental configuration: a vertically-lifting slide (leaf) operating within a frame to control water flow in a channel or aperture.
≈The primary material of construction for the main components (frame and slide) in IS 3042 and its closest equivalent (AWWA C560) is cast iron, chosen for its rigidity and casting properties.
≈The use of dissimilar materials for sealing/seating faces to prevent galling is a common principle. IS 3042 specifies bronze (gunmetal) on cast iron, which is also a primary option in standards like AWWA C560.
≈The basic design principle of using wedges to force the gate leaf against the frame seat to ensure a tight seal under pressure is common to both the IS code and international standards.
