IS 2692:2018 is the Indian Standard (BIS) for ball valves for water supply - specification. This standard specifies the requirements for materials, dimensions, construction, and testing of ball valves used in water supply systems. It defines nominal pressure ratings and hydrostatic test criteria to ensure valve integrity and leak-tightness.
Specifies requirements for full bore and reduced bore ball valves for water supply applications.

Specification for spherical valves (ball valves) of copper alloy for domestic and industrial purposes
This was the British standard for copper alloy ball valves before the adoption of the harmonized European standard EN 13828.
Key Differences
≠IS 2692 specifies two pressure classes (PN 1.0 and PN 1.6), whereas EN 13828 primarily focuses on PN 10 (1.0 MPa) and ASME B16.34 uses a system of pressure classes (e.g., Class 150, 300) with detailed pressure-temperature ratings.
≠EN 13828 includes mandatory requirements and tests for acoustic performance (noise levels), which are not specified in IS 2692.
≠The mechanical endurance test in IS 2692 requires 2,500 cycles (standard) or 10,000 cycles (heavy-duty), while EN 13828 mandates a more stringent 20,000-cycle test for the operating mechanism.
≠IS 2692 references Indian Standards for material specifications (e.g., IS 319 for brass), while EN 13828 specifies European material designations (e.g., CW617N for brass) and lists approved materials for potable water contact.
Key Similarities
≈All standards are based on the quarter-turn operation of a spherical obturator (ball) to control flow.
≈Both IS 2692 and EN 13828 cover a similar nominal size range from DN 8 to DN 100 for water supply applications.
≈All relevant standards mandate hydrostatic pressure testing for both shell integrity (at ~1.5x PN) and seat tightness (at ~1.1x PN) to ensure leak-free performance.
≈The standards require clear and permanent marking on the valve body, including the manufacturer's identity, nominal size (DN), and pressure rating (PN).
≈All standards emphasize that materials in contact with potable water must be corrosion-resistant and must not contaminate the water, often by referencing national regulations or lists of approved materials.
