Thermal solar systems and components - Solar collectors - Part 1: General requirements
This European Standard specifies performance requirements for fluid heating collectors with respect to mechanical resistance to climatic loads, fire safety, weather tightness, release of dangerous substances, electrical safety, operating pressure, sound level, thermal output and collector efficiency. Fluids included are anti-freeze fluids, thermo oil, air and water which are not intended for human consumption. The intended use of the solar collector is to heat up the working fluid. This European Standard also includes provisions for evaluation of conformity to these requirements.
This European Standard covers only the solar collector consisting of its components: i.e. absorber, frame, insulation and glazing; It does not cover the fluid.
It is applicable to glazed and unglazed solar collectors, flat plate solar collectors, evacuated tubular solar collectors, concentrating solar collectors, tracking solar collectors and thermal-electrical hybrid solar collectors (so called PVT solar collectors).
It is not applicable to those solar collectors, in which the thermal storage unit is an integral part of the solar collector to such an extent, that the heat production process cannot be separated from the storage process for the purpose of making measurements of these two processes.
Thermische Solaranlagen und ihre Bauteile - Kollektoren - Teil 1: Allgemeine Anforderungen
Diese Europäische Norm legt Leistungsanforderungen an Flüssigkeitskollektoren im Hinblick auf die mechani-sche Widerstandsfähigkeit gegen klimatische Belastungen, die Feuersicherheit, Wetterdichtheit, Freisetzung von gefährlichen Stoffen, elektrische Sicherheit, den Betriebsdruck, den Schallpegel, die Wärmeleistung und den Kollektorwirkungsgrad fest. Zu den abgedeckten Wärmeträgerfluiden gehören Frostschutzmittel, Wärme-trägeröl, Luft und Wasser, die nicht für den menschlichen Verbrauch vorgesehen sind. Der vorgesehene Ver-wendungszweck des Sonnenkollektors ist die Erwärmung des Arbeitsfluids. Diese Europäische Norm enthält auch Vorgaben für die Bewertung der Konformität mit diesen Anforderungen.
Diese Europäische Norm gilt nur für den Sonnenkollektor und seine Bauteile, d. h. den Absorber, den Rah-men, die Dämmung und die Abdeckung. Sie gilt nicht für das Wärmeträgerfluid.
Diese Norm gilt für abgedeckte und unabgedeckte Sonnenkollektoren, Flachkollektoren, Vakuum-Röhrenkol-lektoren, konzentrierende Sonnenkollektoren, nachgeführte Sonnenkollektoren und thermoelektrische Hybrid-kollektoren (sogenannte PVT-Kollektoren).
Die vorliegende Norm ist nicht auf Sonnenkollektoren anwendbar, bei denen der Wärmespeicher in einem sol-chen Maße in den Kollektor integriert ist, dass bei der Durchführung von Messungen der Wärmeerzeugungs-prozess im Kollektor vom Prozess der Wärmespeicherung nicht getrennt werden kann.
Installations solaires thermiques et leur composants - Capteurs thermiques solaires - Partie 1: Exigences générales
La présente Norme européenne spécifie les exigences de performances des capteurs thermiques solaires à circulation de fluide relatives à la résistance mécanique aux charges climatiques, à la sécurité incendie, à la perméabilité à l'eau, au dégagement de substances dangereuses, à la sécurité électrique, à la pression de fonctionnement, au niveau acoustique, à la production thermique et au rendement du capteur. Les fluides inclus sont des fluides antigel, des pétroles thermiques, de l’air et de l’eau non prévu pour la consommation humaine. L’utilisation prévue des capteurs thermiques solaires est de réchauffer un fluide de travail. La présente Norme européenne donne également des dispositions pour l'évaluation de la conformité à ces exigences.
La présente Norme européenne traite uniquement aux capteurs thermiques solaires constitués de ses composants : c’est-à-dire, l’absorbeur, le bâti, l’isolation et le vitrage ; il ne traite pas des fluides.
Elle s’applique aux capteurs thermiques solaires vitrés et non vitrés, aux capteurs thermiques plan, aux capteurs à tube sous vide, aux capteurs thermiques à concentration, aux capteurs thermiques solaires traquant et aux capteurs hybrides thermiques-photovoltaïques (appelés capteurs thermiques PVT).
Elle ne s'applique pas aux capteurs thermiques dont le dispositif de stockage thermique fait partie intégrante dans la mesure où les opérations de production de chaleur et de stockage de l'énergie ne peuvent pas être séparées en vue d'effectuer des mesures nécessaires.

Introduction
In respect of potential adverse effects on the quality of water intended for human consumption, caused by the
product covered by this standard, it is pointed out that:
a) This standard provides no information as to whether the product may be used without restriction
in any of the Member States of the EU or EFTA;
b) It should be noted that, while awaiting the adoption of verifiable European criteria, existing
national regulations concerning the use and/or the characteristics of this product remain in force.
1 Scope
This European Standard specifies requirements on durability (including mechanical strength), reliability and
safety for fluid heating solar collectors. It also includes provisions for evaluation of conformity to these
requirements.
It is not applicable to those collectors, in which the thermal storage unit is an integral part of the collector to
such an extent, that the collection process cannot be separated from the storage process for the purpose of
making measurements of these two processes.
It is also applicable to thermal-electrical hybrid collectors, so called PVT collectors; however it does not cover
electrical safety or other specific properties related to the PV part of these collectors.Collectors that are
custom-built (built in, roof integrated collectors that do not comprise factory made modules and are assembled
directly on the place of installation) cannot be tested in their actual form for durability, reliability and thermal
performance according to
