Solar collectors - General requirements
This document is applicable to all types of fluid heating solar collectors. This European Standard specifies performance requirements for fluid heating solar collectors with respect to durability, reliability, safety and thermal performance. This European Standard includes provisions for the assessment and verification of constancy of performance to these requirements.
This document deals with the collector module and not with assemblies. This document is not applicable to those devices in which a thermal storage unit is an integral part to such an extent that the collection process cannot be separated from the storage process for making the collector thermal performance measurements.
Kollektoren - Allgemeine Anforderungen
Dieses Dokument ist für alle Arten von fluiderhitzenden Sonnenkollektoren anwendbar. Diese Europäische Norm legt die Anforderungen an die Leistungsfähigkeit von fluiderhitzenden Sonnenkollektoren hinsichtlich Dauerhaftigkeit, Zuverlässigkeit, Sicherheit und thermischer Leistungsfähigkeit fest. Diese Europäische Norm enthält Vorgaben für die Bewertung und Überprüfung der Leistungsbeständigkeit.
Dieses Dokument behandelt das Kollektormodul und nicht die Baugruppen. Dieses Dokument ist nicht auf solche Geräte anwendbar, bei denen der Wärmespeicher in einem solchen Maß integriert ist, dass bei der Messung der thermischen Leistungsfähigkeit am Kollektor der Wärmeerzeugungsprozess nicht vom Prozess der Wärmespeicherung getrennt werden kann.
Capteurs solaires - Exigences générales
Le présent document s'applique à tous les types de capteurs solaires à circulation de fluide. La présente Norme européenne spécifie les exigences de performance pour les capteurs solaires à circulation de fluide en ce qui concerne la durabilité, la fiabilité, la sécurité et la performance thermique. La présente Norme européenne comprend des dispositions pour l'évaluation de la performance et la vérification de sa constance par rapport à ces exigences.
Le présent document traite du module de capteur et non de l’assemblage. Le présent document ne s'applique pas aux appareils dans lesquels un dispositif de stockage thermique fait partie intégrante dans la mesure où les opérations de captage et de stockage de l'énergie ne peuvent pas être séparées en vue d'effectuer des mesures de performance thermique du capteur.

1 Scope
This document is applicable to all types of fluid heating solar collectors. This European Standard
specifies performance requirements for fluid heating solar collectors with respect to durability,
reliability, safety and thermal performance. This European Standard includes provisions for the
assessment and verification of constancy of performance to these requirements.This document deals with the collector module and not with assemblies. This document is not
applicable to those devices in which a thermal storage unit is an integral part to such an extent that the
collection process cannot be separated from the storage process for making the collector thermal
performance measurements.2 Normative references

4 Symbols and abbreviations
For the purposes of this European Standard, the symbols, abbreviations and units given in EN ISO 9488
and EN ISO 9806:2017 apply.5 Requirements
5.1 General
Collectors shall be tested according to 5.3. For the declarations of performance of a solar collector as
required in the Z-Annexes, additional tests (5.4) or conversions of test results into other formats may be
required (A.1).5.2 Safety
Materials to be used in the collector and in the installation incorporating collectors shall be chosen
taking into account the expected maximum local temperatures with respect to e.g. melting, burning,
self-ignition, or any other kind of degradation.5.3 Required tests
Collectors shall be tested according to Table 1 of EN ISO 9806:2017 considering the provision of
Clause 5 of EN ISO 9806:2017. The measurement of the pressure drop (Clause 27 of EN ISO 9806:2017)
is recommended but not mandatory. The results shall be reported as required in the corresponding
clauses and in Annex A of EN ISO 9806:2017.None of the findings of the performed tests shall be rated as “major failure” according to Clause 17 of
EN ISO 9806:2017.5.4 Additional tests for the purpose of the Z-annexes
5.4.1 Fire safety
Reaction to fire: If required, collectors that are not classified without testing shall be tested according to
EN 13501-1 applying the standards therein as applicable and following Annex C for the selection,
preparation, mounting, fixing as well as Annex ZA for the field of application of the collector.
External fire performance: If required, collectors embedded in the roof shall be tested and classified in
accordance with EN 13501-5 applying the standards therein, as applicable and Annex D for the
selection, preparation mounting and fixing and field of application of the collector.
5.4.2 Release of dangerous substancesNational regulations on dangerous substances may require verification and declaration on release, and
sometimes content, when construction products covered by this European Standard are placed on those
markets. In the absence of European harmonized test methods, verification and declaration on
release/content should be done taking into account national provisions in the place of use.
NOTE An informative database covering European and national provisions on dangerous substances is
available at https://ec.europa.eu/growth/tools-databases/cp-ds_en5.4.3 Surface temperature
Harmful surface temperatures on a solar thermal collector are linked to a malfunction of the collector
that are rated as major failure according to Clause 17 of EN ISO 9806:2017. The surface temperatures of
parts that are associated with the transmission of heat are excluded. No findings with a rating as
“2 - major failure” according to Clause 17 of EN ISO 9806:2017 thus confirms that no harmful
temperatures on the surface of the collector are expected.---------------------- Page: 9 ----------------------

5.4.4 Electrical safety
If required, collectors co-generating or using electricity shall comply with the specific requirements of
the applicable standards and regulations for such products (See also Annex ZG).5.4.5 Sound level
If applicable, the sound level shall be tested and the results shall be reported according to either
ISO 3741, EN ISO 3743-2 or EN ISO 37475.5 Classification of collectors with respect to their hydraulic system
Collectors shall be classified with respect to their intended use and their intended fluids (Group 1 or
Group 2 fluids) into one or several collector classes defined in Table 1 — Collector classes with respect
to the hydraulic system.Table 1 — Collector classes with respect to the hydraulic system
Collector class Definition
