IS 1703:2000 is the Indian Standard (BIS) for water fittings - copper alloy float valves (horizontal plunger type). This standard prescribes the requirements for materials, dimensions, manufacture, workmanship, and testing of horizontal plunger type copper alloy float valves used for water supply in cisterns, overhead tanks, and similar fixtures.

| Parameter | IS Value | International | Source |
|---|---|---|---|
| Material for Body | Copper Alloy (e.g., Brass as per IS 318, IS 1264) | Brass or Bronze (e.g., Dezincification Resistant (DZR) Brass, Low-Lead Brass) | BS 1212-1:1990, EN 14124:2004, ASME A112.18.1/CSA B125.1-2018 |
| Maximum Working Pressure | 1.0 MPa (10 bar) | Up to 1.0 MPa (10 bar) or higher (e.g., 1.6 MPa) | BS 1212-1:1990, EN 14124:2004 |
| Connection Thread Type | As per IS 554 (equivalent to ISO 7-1, i.e., BSP) | BSP (Parallel or Taper) or NPT/IPS | BS 1212-1:1990, ASME A112.18.1/CSA B125.1-2018 |
| Leakage Test (Shut-off) | No visible leakage under working pressure for 1 minute | Maximum drip rate (e.g., no drops per minute or max 0.2 ml/min) after shut-off at specified pressures | EN 14124:2004, AS/NZS 1172.2:2014 |
| Lead Content in Alloy (for potable water contact) | Up to 3.5% (common for brass grades specified in IS 318, IS 1264) | < 0.25% (lead-free or low-lead brass) for potable water applications | ASME A112.18.1/CSA B125.1-2018, EN 14124:2004 (referencing potable water directives) |
| Endurance/Life Cycle Test | Not explicitly detailed for plunger type in common summaries (general mechanical tests apply) | 100,000 to 200,000 cycles | EN 14124:2004 (e.g., 200,000 cycles), AS/NZS 1172.2:2014 |
