Overview
EN 1074-2:2000 (CEN) - Valves for water supply - Fitness for purpose requirements and appropriate verification tests - Part 2: Isolating valves - defines the minimum fitness for purpose requirements and verification testing for isolating valves used in water supply systems. The standard applies to valves installed above or below ground and to systems carrying raw or treated water, including uses such as irrigation, fire fighting and meter valves (see prEN 805). EN 1074-2 sets out expectations for performance, durability and test methods to ensure valves are suitable for service in distribution networks.
Key Topics
- Scope and applicability: Requirements for isolating (shut‑off) valves connected to water supply pipe systems above or below ground, and for both treated and raw water applications.
- Fitness for purpose: Minimum functional requirements that valves must meet to be considered suitable for intended uses (reliability, operational performance, leak tightness).
- Verification tests: Appropriate laboratory and factory tests to confirm performance (pressure testing, leakage checks, endurance and operational tests - as specified within the standard).
- Materials and construction considerations: Expectations for materials selection, corrosion resistance and construction practices that affect long‑term serviceability in potable and non‑potable water systems.
- Marking and documentation: Requirements for identification, traceability and technical documentation to support selection, installation and maintenance.
- Compatibility with piping systems: Integration with pipe systems and meter installations as referenced to prEN 805.
Applications
EN 1074-2 is used to:
- Guide manufacturers developing isolating valves to meet European minimum performance standards.
- Help water utilities and municipal engineers specify valves for distribution, fire protection and irrigation networks.
- Support procurement teams in writing technical specifications and acceptance criteria.
- Assist testing laboratories and quality assurance teams in verifying valve conformity via appropriate tests.
- Inform consulting engineers, installers and maintenance staff on expected performance and compliance for reliable operation.
