Valves for water supply - Fitness for purpose requirements and appropriate verification tests - Part 3: Check valves

This European Standard defines the minimum fitness for purpose requirements for check valves to be used in, or connected to, water supply pipe systems, above orbelow ground (see prEN 805:1996), carrying water intended for human consumption.This standard specifies the design requirements, the performance requirements and the conformity assessment method for check valves, whatever their type and materials. This standard applies in priority to any product or test standard: the requirements from other standards apply only when this standard refers to them.

Armaturen für die Wasserversorgung - Anforderungen an die Gebrauchstauglichkeit und deren Prüfung - Teil 3: Rückflußverhinderer

Diese Europäische Norm legt die Mindestanforderungen an die Gebrauchstauglich- keit von Rückflußverhinderern fest, die in oberirdisch oder erdverlegten Rohrleitungssystemen für die Wasserversorgung verwendet werden, oder mit diesenverbunden sind (siehe prEN 805:1996), die Wasser führen, welches für den menschlichen Verbrauch bestimmt ist. Diese Norm legt die Konstruktions- anforderungen, die Gebrauchstauglichkeitsanforderungen und das Konformitäts- bewertungsverfahren für Rückflußverhinderer, unabhängig von ihrer Bauart oder ihren Werkstoffen, fest.

Robinetterie pour l'alimentation en eau - Prescriptions d'aptitude à l'emploi et vérifications s'y rapportant - Partie 3: Clapets de non retour

La présente norme européenne définit les prescriptions d'aptitude à l'emploi minimales des appareils de robinetterie de type clapets de non retour à utiliser dans, ou connectés à, des réseaux d'alimentation en eaux aériens ou enterrés (voir prEN 805:1996), et aussi utilisables pour des réseaux véhiculant de l'eau destinée à l'alimentation humaine. Cette norme s'applique en priorité à toute autre norme de produit ou d'essai; les prescriptions des autres normes s'appliquent seulement lorsque cette norme y fait référence.

Overview

EN 1074-3:2000 (CEN) defines minimum fitness-for-purpose requirements and appropriate verification tests for check valves used in water supply systems. The standard applies to check valves installed in or connected to potable water pipe systems, both above and below ground, and covers valves made from any material or of any type. EN 1074-3 specifies design requirements, performance requirements and the conformity assessment method to ensure check valves are suitable for carrying water intended for human consumption.

Key topics and requirements

• Scope and applicability: Applies to check valves in water supply pipe systems carrying potable water; takes priority over product/test standards unless those are explicitly referenced.
• Design requirements: Sets baseline expectations for valve construction to ensure reliability, durability and hygienic suitability for drinking water networks.
• Performance requirements: Defines functional criteria a check valve must meet (e.g., prevention of backflow, operational stability) through appropriate verification methods.
• Verification tests: Requires appropriate tests to confirm compliance with the performance and design requirements; the standard identifies the types of verification deemed suitable without prescribing proprietary test values.
• Conformity assessment: Specifies how manufacturers or suppliers should demonstrate conformity to the standard - covering documentation, testing evidence and assessment procedures.
• Material and type independence: Requirements apply regardless of valve material (metal, plastic, composite) or mechanical type (swing, lift, spring-assisted), ensuring broad applicability.

Practical applications

Who uses EN 1074-3 and why:

• Manufacturers: To design, test and document check valves that meet European fitness-for-purpose requirements for potable water systems.
• Water utilities and network designers: To select check valves that comply with recognized performance and safety expectations for drinking water distribution.
• Specifiers and procurement teams: To include clear compliance criteria in tender documents and supplier evaluations.
• Testing laboratories and conformity assessors: To perform verification tests and certify products against the standard.
• Regulators and certification bodies: To reference a harmonized standard for public health protection and system integrity.

Related standards

• EN 1074 (series) - other parts of the EN 1074 family cover additional valve types and related requirements.
• prEN 805:1996 - referenced for application context in water supply systems carrying potable water.
• Note: EN 1074-3 takes precedence over other product/test standards unless those are formally referenced.
