Ventilation for buildings - Chilled ceilings - Testing and rating
This European Standard specifies test conditions and methods for the determination of the cooling capacity of chilled ceilings and other extended chilled surfaces.
The purpose of the Standard is to give comparable and repeatable product data.
The test method applies to all types of surface cooling systems using any medium as energy transport medium.
NOTE The result is valid only for the specified test set up. For other conditions (i.e. different positions of heat loads, forced flow around the test object, variations in surface area) the producer should give guidance based on full-scale tests.
This standard refers to water as the cooling medium throughout, however wherever water is specified any other cooling medium can also be used in the test. Where air is the transport medium this air may not be discharged into the test room. In addition, this standard refers to chilled surfaces and where "surfaces" are specified this should be taken to include ceiling, wall or floor as appropriate.
Lüftung von Gebäuden - Kühldecken - Prüfung und Bewertung
Diese Europäische Norm legt Prüfbedingungen und Verfahren zur Bestimmung der Kühlleistung von Kühldecken oder anderen größeren Kühlflächen fest.
Ziel dieser Norm ist es, vergleichbare und reproduzierbare Produktkennwerte zur Verfügung zu stellen.
Das Prüfverfahren gilt für sämtliche Bauarten von Kühlflächensystemen, die jedes Medium als Energietransportmedium verwenden.
ANMERKUNG Das Ergebnis ist nur für den festgelegten Prüfaufbau gültig. Bei anderen Bedingungen (z. B. anderer Anordnungen der Wärmelasten, erzwungene Strömung um den Prüfgegenstand, Veränderungen der Oberfläche) sollte der Hersteller Anleitungen geben, die auf gründlicher Prüfung beruhen.
Diese Norm bezieht sich durchgängig auf Wasser als Kühlmedium, es kann jedoch bei den Prüfungen, bei denen Wasser festgelegt ist, auch jedes andere Kühlmedium verwendet werden. Ist Luft das Transportmedium, darf diese Luft nicht in den Prüfraum gelangen. Weiterhin bezieht sich diese Norm auf Raumkühlflächen und wenn ¿Flächen" angegeben sind, sollten sie, soweit zutreffend, Decken, Wände oder Fußböden einschließen.
Ventilation de bâtiments - Plafonds refroidis - Essais et évaluation
La présente Norme européenne spécifie les conditions et méthodes d'essai pour la détermination de la puissance frigorifique des plafonds refroidis et autres parois refroidies allongées.
La norme vise à attribuer aux produits des données comparables et répétables.
La méthode d'essai est applicable à tous les types de systèmes de refroidissement par les parois, quel que soit le fluide utilisé pour véhiculer l'énergie.
NOTE Le résultat ne vaut que pour la configuration d'essai spécifiée. Pour d'autres conditions (positions différentes des sources de chaleur, ventilation forcée autour du corps d'épreuve, aire de paroi différente) il convient que le fabricant donne des indications basées sur des essais en vraie grandeur.
Dans toute la présente norme il est fait référence à l'eau en tant qu'agent de refroidissement, toutefois lorsque l'eau est spécifiée tout autre agent de refroidissement peut toujours être également utilisé pour l'essai. Si le fluide de transport est l'air, cet air ne doit pas être insufflé dans la chambre d'essai. En outre, la présente norme se réfère à des parois refroidies et lorsque des « parois » sont spécifiées il convient d'y inclure le cas échéant plafonds, murs ou planchers.

EN 14240:2004 - Overview
EN 14240:2004, published by CEN, defines test conditions and laboratory methods for the determination and rating of the cooling capacity of chilled ceilings and other extended chilled surfaces. Its primary purpose is to provide comparable and repeatable product data for surface cooling systems. The standard is written with water as the reference cooling medium but allows other media to be used; when air is the transport medium, that air must not be discharged into the test room. Results apply to the specified test setup only - producers should provide guidance or full‑scale test data for other installation conditions.
Key Topics
- Scope and applicability
- Applies to all types of surface cooling systems (ceilings, walls, floors) and any energy transport medium.
- Test conditions and methods
- Defines laboratory test setups and measurement methods used to determine cooling capacity and produce rating data.
- Repeatability and comparability
- Emphasis on standardized conditions so manufacturers and test labs produce consistent product data.
- Cooling medium guidance
- Uses water as the reference medium; other media permitted where appropriate.
- Limitations and test validity
- Explicit note that results are valid only for the specified test configuration (heat load positioning, surface area, surrounding flow conditions).
- Definitions
- Clarifies terminology for “chilled surfaces,” including ceiling, wall, and floor applications.
Applications
EN 14240:2004 is practical for:
- Manufacturers of chilled ceilings and radiant surface cooling systems - to rate products and publish comparable cooling capacity data.
- Independent test laboratories - to perform standardized laboratory testing and certification.
- HVAC consultants and design engineers - to interpret laboratory ratings when specifying systems for building projects.
- Specifiers and procurement teams - to compare product performance across suppliers using common test data.
- Facility managers and commissioning agents - to validate manufacturer data against expected in‑building performance and to request full‑scale tests or guidance for site‑specific conditions.
Related Standards
- Consult other CEN or ISO standards covering ventilation, indoor environmental performance, and HVAC testing methods for complementary requirements and in‑situ testing protocols.
- For project-specific design, combine EN 14240 product ratings with building‑scale thermal and airflow standards or guidelines.

The EN 14240:2004 standard presents a comprehensive framework for the testing and rating of chilled ceilings and other extended chilled surfaces in ventilation systems. Its primary scope is to establish uniform test conditions and methodologies to determine the cooling capacity of various surface cooling systems effectively. One of the strengths of this standard is its applicability across all types of surface cooling systems, allowing for the use of any medium as an energy transport medium, which enhances its versatility and relevance in modern building ventilation design. The standard's emphasis on delivering comparable and repeatable product data is particularly noteworthy. This consistency is essential for manufacturers and builders seeking reliable performance metrics for their chilled ceiling products, ultimately contributing to improved energy efficiency and indoor comfort. The provision that results are valid specifically for the defined test setup is crucial for ensuring accurate assessments, while also recognizing the need for guidance from producers when variations occur in real-world applications. Another significant aspect of EN 14240:2004 is its flexibility concerning the cooling medium. While the standard primarily references water, it explicitly permits the use of other cooling mediums in testing, thereby accommodating a wide array of technologies and innovations in the field. Additionally, the standard clarifies the conditions under which air, as a transport medium, must be handled, avoiding potential complications that could arise from air discharge into the test room. Furthermore, the inclusivity of various surfaces, including ceilings, walls, and floors, under the term "chilled surfaces," broadens the standard's applicability in various architectural designs. This comprehensive scope ensures that the EN 14240:2004 supports a wide range of building projects, making it a pivotal reference for industry professionals involved in the design and implementation of effective ventilation systems. Overall, the EN 14240:2004 standard stands out for its detailed approach to testing chilled ceilings and other related surfaces, reinforcing its relevance in promoting energy-efficient building practices while ensuring comfort through effective ventilation solutions.
