Thermal solar systems and components - Solar collectors - Part 2: Test methods
This European Standard specifies test methods for validating the durability, reliability and safety requirements
for liquid heating collectors as specified in EN 12975-1. This standard also includes three test methods for the
thermal performance characterisation for liquid heating collectors.
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 basically applicable to tracking concentrating collectors, thermal performance testing as given in 6.3
(quasi dynamic testing) is also applicable to most concentrating collector designs, from stationary non-imaging
concentrators as CPCs to high concentrating tracking designs. Parts of the solar radiation measurement
should be adjusted in case of a tracking collector and in case a pyrheliometer is used to measure beam
radiation.
Collectors that are custom built (built in; e.g. roof integrated collectors that do not compose of 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 may be tested. The module gross area should be at least 2 m2. The test is
valid only for larger collectors than the tested module.
Diese Europäische Norm legt Prüfverfahren für den Nachweis der Erfüllung der Dauerhaftigkeits- und Zuverlässigkeitsanforderungen für Flüssigkeitskollektoren fest. Diese Norm enthält auch drei Prüfverfahren für die Charakterisierung der Leistung von Flüssigkeitskollektoren. Die Norm ist nicht auf Kollektoren anwendbar, bei denen der Wärmespeicher in einem solchen Maße in den Kollektor integriert ist, dass bei der Durchführung der Messungen der Prozess im Kollektor von der Wärmespeicherung nicht getrennt werden kann.
