Introduction
BIS Certification for Copper Alloy Float Valves under IS 1703:2000 confirms that the main water control devices comply with the quality and safety standards prescribed by the Bureau of Indian Standards (BIS). Copper alloy float valves find diverse applications such as water storage tanks, plumbing systems, and industrial sectors where they help in automatic water level changes and overflow prevention.The certification acts as a quality assurance for the use of superior copper alloys in the valves manufacturing along with the implementation of durability, corrosion resistance and high performance designs. Through the IS 1703:2000 standard compliance, manufacturers convey their sincerity towards creating dependable and safe products not only for the domestic but also for commercial sectors.
What is IS 1703:2000?
IS 1703:2000 is a standard in India, established by the Bureau of Indian Standards (BIS), aiming to lay down the specifications for copper alloy float valves (horizontal plunger type) used in water storage systems.
Key Points:
- Scope of the Standard : It specifies the requirement for copper-alloy float valves for automatic control of water levels in tanks and cisterns.
- Material Specifications : The standard sets the nature and chemical composition of the copper alloys so as to achieve strength, durability, and resistance to corrosion.
- Design and Construction Requirements : It specifies the requirements for material, detailed drawings, workmanship, and assembly of the valve, to ensure that it will operate properly.
- Performance and Testing Criteria: The standard IS 1703:2000 lays down the detailed test methods like pressure test, leakage test, and operational checking for confirming the performance of the product.
- Marking and Certification : BIS certification is granted to the products conforming to this standard and such products can carry the ISI mark which is a mark of quality and compliance.
Products Covered Under IS 1703 : 2000
IS 1703:2000 covers float valves of different types made of copper alloy (horizontal plunger type) used for water level control in tanks and water storage systems. The standard is to ensure that all these products comply with certain quality and performance requirements.
Key Reasons:
- Horizontal plunger type float valves: These represent the main category of goods covered by the standard that regulate the water flow automatically depending on the float position.
- Float valves for domestic water tanks: They are installed in the overhead water tanks, underground tanks, and cisterns of houses to avoid overflow and to keep the water level stable.
- Float valves for commercial and industrial use: They can be used in the large storage tanks, industrial water systems, and commercial plumbing applications.
- High and low pressure float valves: The standard encompasses valves that are capable of functioning effectively in different water pressure scenarios.
- Valves with copper alloy components: It embraces the valves which are constructed fully or partially from copper alloys, such as bodies, plungers, and other essential parts that guarantee durability and resistance to corrosion.
Importance and Benefits of BIS Certification
| Importance | Benefits |
