Thermal solar systems and components - Solar collectors - Part 1: General requirements

This European Standard specifies requirements on durability (including mechanical strength), reliability and safety for liquid 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 extend, that the collection process cannot be separated from the storage process for the purpose of making measurements of these two processes. It is not applicable to tracking concentrating solar 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 this standard. Instead, a module with the same structure as the ready collector is tested. The module gross area in the case of custom built collectors should be at least 2m2.The test is valid only for larger collectors, than the tested module.
For collectors the national and European Guidelines for Structural Planning and overhead glazing are not valid. Therefore this standard should be applied for the design of the static of the collector.

Thermische Solaranlagen und ihre Bauteile - Kollektoren - Teil 1: Allgemeine Anforderungen

Diese Europäische Norm legt für Flüssigkeitskollektoren Anforderungen hinsichtlich der Dauerhaftigkeit (ein-schließlich der mechanischen Festigkeit), der Zuverlässigkeit und Sicherheit fest. Sie enthält auch Vorgaben, um die Konformität mit diesen Anforderungen zu bewerten.
Die vorliegende Norm ist nicht auf Kollektoren anwendbar, bei denen der Wärmespeicher in einem solchen Maße in den Kollektor integriert ist, dass bei der Durchführung von Messungen der Prozess im Kollektor vom Prozess der Wärmespeicherung nicht getrennt werden kann.
Die vorliegende Norm gilt für thermoelektrische Hybridkollektoren, sogenannte PVT-Kollektoren; sie behandelt jedoch nicht die elektrische Sicherheit oder andere auf den PV-Teil dieser Kollektoren bezogene spezifische Eigenschaften. Kundenspezifische Kollektoren (in der Dacheindeckung integrierte Kollektoren, die keine industriell hergestellten Module enthalten und direkt am Einsatzort zusammengestellt werden) können in ihrer ursprüng¬lichen Form in Bezug auf Dauerhaftigkeit, Zuverlässigkeit und Wärmeleistung nicht nach dieser Norm geprüft werden. An ihrer Stelle wird ein Modul geprüft werden, das die gleiche Bauweise wie der fertig mon-tierte Kollektor aufweist. Die Bruttofläche des Moduls sollte mindestens 2 m2 betragen. Die Prüfung gilt aus-schlie߬lich für Kollektoren, die größer sind als das geprüfte Modul.
Für Kollektoren gelten nicht die nationalen und europäischen Richtlinien zur Bauplanung und Decken-verglasung. Deshalb sollte die vorliegende Norm zur Bemessung der Kollektorstatik angewendet werden.

Installations solaires thermiques et leurs composants - Capteurs 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.

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 this standard. Instead, a module with the same structure as the ready collector is
2
tested. The module gross area in the case of custom built collectors should be at least 2 m . The test is valid
only for larger collectors, than the tested module.
For collectors the national and European Guidelines for Structural Planning and overhead glazing are not valid.
Therefore this standard should be applied for the design of the static of the collector.

This test shall be carried out only in the cases specified in 5.9.1 of EN 12975-2:2006. The pass criterion is no
major failure as defined in 5.3.1 after three freeze-thaw cycles.
5.4 Procedure
The required number of collectors shall be available for testing. The collectors shall be tested in accordance
with 5.2. The collectors conform to this standard, only if all pass criteria are fulfilled.
Freeze resistance shall be tested, for collectors which the manufacturer claims can withstand freezing and
freeze/thaw cycling or if the collector contains fluids with the risk of freezing (like e.g. within some heat
pipes).and which are not intended to be filled with antifreeze fluids or air.
5.5 Fire characteristic
5.5.1 Reaction to fire
If necessary the materials used in solar collectors shall be tested and classified in accordance with EN 13501-
1.
5.5.2 External fire performance
If necessary in roof collectors shall be tested and classified in accordance with EN 13501-5.
5.6 Weather tightness (in roof and in façade collectors only)
In case of an in roof or in façade installation of the collector a test sample composed of collector, roof (façade)
segment and mounting kit shall be subject to the test according to 5.3.7 or EN 1027. A visual check shall not
show any water ingress caused by the mounting kit.
6 Evaluation of conformity
6.1 General
The compliance of solar collectors with the requirements of this standard and with the declared values
(including classes) shall be demonstrated by:
- Initial Type Testing;
11

---------------------- Page: 13 ----------------------
oSIST prEN 12975-1:2011
prEN 12975-1:2011 (E)
- Factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the
product.
6.2 Initial Type Testing – Type Testing
6.2.1 General
Initial Type Testing and Type Testing shall be performed to demonstrate compliance with this European
standard.
All essential characteristics for which the manufacturer declares performances are subject to Initial Type
Testing. In addition, the need to perform Type Tests applies to all other characteristics included in a standard
when the manufacturer claims compliance, unless the standard gives provisions (e.g. use of previously
existing data, CWFT and conventionally accepted performance) for declaring performances without
performing tests.
Tests previously performed in accordance with the provisions of this standard, may be taken into account
provided that they were made to the same or a more rigorous test method, under the same system of
attestation of conformity on the same product or products of similar design, construction and functionality,
such that the results are applicable to the product in question.
Note 1 Same system of attestation of conformity means testing by an independent third party.
 For the purposes of testing, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characteristics from any one product within the family are
representative for that same characteristics for all products within that same family (a product may be in
different families for different characteristics).
Note 2 Products may be in different families for different characteristics.
Note 3 Reference to the test method standards should be made to allow the selection of a suitable representative sample.
In addition, Type Tests or Initial Type Testing shall be performed for all characteristics included in the
standard for which the manufacturer declares performances:
- at the beginning of the production of a new or modified solar collector (unless a member of the same
family), or
- at the beginning of a new or modified method of production (where this may affect the stated properties); or
they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the solar collector
design, in the raw material or in the supplier of the components, or in the production process (subject to the
definition of a family), which would affect significantly one or more of the characteristics.
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of compliance with other product standards, these characteristics need not be re-
assessed. The specifications of these components shall be documented, as shall be included in the inspection
scheme for ensuring their compliance.
Products marked in accordance with appropriate harmonized European specifications may be presumed to
have the performances stated with that marking, although this does not replace the responsibility on the solar
