Overview
EN 1490:2000 (CEN) specifies requirements and test methods for combined temperature and pressure relief valves used on storage water heaters. The standard covers valves of nominal sizes DN 15 to DN 40, with working pressures from 0.1 MPa (1 bar) to 1.0 MPa (10 bar) and is applicable to storage water heaters with a maximum distribution temperature of 95 °C, regardless of energy source. EN 1490 defines dimensions, materials and performance requirements, and includes methods of test to verify compliance.
Key Topics and Requirements
- Scope and applicability: Valves intended for fitting to storage water heaters in building water supply systems.
- Dimensions and materials: Specifies required physical dimensions and material considerations to ensure compatibility and durability.
- Performance requirements: Sets functional expectations for combined temperature and pressure relief valves, including discharge behaviour under over-temperature and over-pressure conditions.
- Methods of test: Includes standardized test procedures to verify valve performance, safety, and reliability (pressure testing, temperature response and functional testing are addressed in the standard).
- Rated sizes and pressures: Applies to nominal sizes DN15–DN40 and working pressures 0.1–1.0 MPa.
- Maximum temperature: Designed for systems with distribution temperatures up to 95 °C.
Applications
EN 1490 is practical for anyone involved in the safety, design, manufacture, installation or testing of building hot water systems:
- Manufacturers of combined temperature and pressure relief valves use EN 1490 to design products and demonstrate conformity for the European market.
- Testing laboratories and certification bodies apply the standard’s methods of test to verify performance and safety.
- Plumbing and HVAC engineers reference EN 1490 when specifying valves for storage water heaters and hot water systems.
- Installers and maintenance teams use the standard to select compliant valves and to understand expected operational behavior.
- Procurement and regulatory bodies use EN 1490 to set procurement specifications and to ensure installations meet European safety expectations.
Related Standards
EN 1490 complements other European and national standards concerned with building valves, pressure relief devices and hot water system safety. For comprehensive compliance and system design, consult relevant CEN standards on water heaters, pressure relief devices and plumbing fittings.
This summary helps manufacturers, engineers and safety professionals understand EN 1490’s scope and practical use when working with combined temperature and pressure relief valves in building water supply systems.
