IS 13349:1992 is the Indian Standard (BIS) for cast iron single faced thimble mounted sluice gates. This standard specifies the requirements for cast iron, single-faced, thimble-mounted sluice gates used for controlling water flow in open channels. It covers materials, dimensions, manufacturing, workmanship, testing, and marking for gates ranging from 200 mm to 1200 mm in size. The standard is intended for gates operating under a maximum head of 6 meters.

Key Differences
≠IS 13349 is exclusively for 'thimble mounted' gates, where a cast iron sleeve is embedded in concrete for mounting. International standards like AWWA C501 cover thimbles as one of several mounting options, including direct wall mounting.
≠IS 13349 specifies fixed design heads (up to 6m seating, 3m unseating). AWWA C501 is more flexible, allowing gates to be designed for higher or specific heads as required by the purchaser.
≠The standards reference different national material specifications. IS 13349 uses Indian Standard (IS) grades for cast iron, bronze, and steel, while AWWA standards use ASTM (American Society for Testing and Materials) grades.
≠IS 13349 requires manual operation testing for a minimum of three full cycles, whereas AWWA C501 requires at least five cycles of operation for shop testing.
Key Similarities
≈Both IS 13349 and AWWA C501 specify grey cast iron as the primary material for the gate frame, shutter (slide), and guides, recognizing its durability and suitability for water applications.
≈The acceptable leakage rates under both seating and unseating pressure are virtually identical between IS 13349 and its closest equivalent, AWWA C501.
≈Both standards mandate the use of corrosion-resistant materials for critical components. Seating faces and wedges are typically bronze or stainless steel, and the operating stem is made from high-strength bronze or stainless steel.
≈The fundamental design principle is the same: a vertically sliding, single-faced gate designed to control water flow under specified pressure heads, with metal-to-metal or resilient seating.

Table 1 - Materials for various components of sluice gates
Stainless steel conforming to Grade 04Cr13 of IS 6603 is standard, unless otherwise agreed upon (Clause 4.1.2).
What is the maximum leakage allowed during the seating test?+
The leakage rate shall not exceed 1.25 litres per minute per metre of the perimeter of the sealing face (Clause 9.4.1).
What is the required hydrostatic test pressure for the gate assembly?+
The gate assembly must be tested at 1.5 times the maximum design head, with a minimum pressure of 0.1 N/mm² (approx. 10.2m water head), for 15 minutes without showing any signs of leakage (Clause 9.3).
What sizes do these standard gates come in?+
The standard covers nominal sizes ranging from 200 mm to 1200 mm (Table 2).
