- BIS Certification for Ferrules for Water Services ensures compliance with IS 2692:1989.
- The ISI mark confirms leak-proof strength, corrosion resistance, and long service life.
- Diligence Certification assists manufacturers through testing, documentation, and BIS license renewal.
Introduction
A manufacturing company of hardware in Ludhiana lost the municipal water-supply tender because their Ferrules for Water Services did not have BIS Certification under IS 2692:1989 for certification. Although their rules had been checked for quality compliance through in-house checks, the tender committee refused to take the bid, citing the BIS Act, 2016 the mandated using ISI-marked product component for public owned water infrastructure.
This is not an isolated case. Many manufacturers overlook the importance of a BIS certification until they are restricted from supplying water services under a public tender or face legal penalties.
Having BIS Certification for Ferrules for Water Services allow manufacturers to legally supply, sell, and export those products within India and demonstrate that the products comply with the national standard IS 2692:1989 — to guarantee safe, durability, and performance for every installation.
Diligence Certification has dedicated to support and guide manufacturers throughout the entire process of having products tested, factories inspected, and issuing and renewing licenses for BIS compliance.
What is IS 2692:1989?
IS 2692:1989 is an Indian Standard published by the Bureau of Indian Standards (BIS) specifying requirements for Ferrules used in Water Services. Ferrules, small – but significant, brass fittings consist of a Female Connection, that connects water service pipes to mains which are leak-tight, and corrosion resistant within a distribution system.
Key Technical Parameters of IS 2692:1989
1. Material Composition:
Ferrules must be made from high-grade brass (copper-zinc alloy) to resist corrosion and ensure longevity under continuous water pressure.
2. Threading and Dimensions:
The standard defines thread pitch, diameter, and tolerance to ensure perfect compatibility with standard water service pipes.
3. Mechanical Strength:
Ferrules must withstand specified hydraulic pressures without cracking or deformation.
4. Leakage and Pressure Tests:
Every ferrule undergoes leak-proof testing under controlled pressure conditions.
5. Marking Requirements:
Each BIS-certified ferrule must carry the ISI mark, manufacturer’s name or code, and batch number.
6. Finish:
The product surface must be smooth, free from cracks, and finished to prevent contamination or leakage.
Why BIS Certification for Ferrules for Water Services is Essential
1. Legal Requirement under BIS Act, 2016
Manufacturers cannot produce, sell, or distribute ferrules for domestic water systems without a valid BIS license as per IS 2692:1989.
Violation of this norm can result in penalties, confiscation, or closure under Section 17 of the Act.
2. Assurance of Product Safety and Reliability
BIS-certified ferrules undergo pressure and leak tests to ensure safety in potable water supply, maintaining system integrity for years.
3. Tender and Market Access
Government departments, water boards, and smart city projects only procure ISI-marked ferrules, making certification a direct gateway to larger contracts.
4. Brand Reputation and Trust
The ISI mark enhances brand credibility, demonstrating adherence to India’s strict quality regulations and boosting buyer confidence.
5. Support to “Make in India”
Standardizing local production under IS 2692:1989 promotes Indian manufacturers’ global competitiveness and aligns with Atmanirbhar Bharat objectives.
Understanding the ISI Mark for Ferrules for Water Services
The ISI mark is the symbol of trust and compliance.
For ferrules, it certifies that the product has been tested under IS 2692:1989 and verified for:
- Dimensional accuracy and thread precision
- Pressure and leakage resistance
- Chemical composition of bras
- Surface quality and finish consistency
- Batch traceability and inspection history
Each ISI-marked ferrule is traceable through its license number, ensuring transparency from production to installation.
