Overview

This European Standard is applicable to the determination of the long term behaviour and service life of selective solar absorbers for use in vented flat plate solar collectors working under conditions corresponding to that in a typical solar domestic hot water system. This European Standard specifies a failure criterion of a solar absorber based on changes in optical performance of the absorber. The optical properties of interest are solar absorptance and thermal emittance. This European Standard specifies durability testing procedures focused on resistance to high temperatures and condensation of water on the absorber surface as well as high humidity in the presence of sulphur dioxide. This document has been prepared by Technical Committee CEN/TC 312 "Thermal solar systems and components" (secretariat: ELOT, Greece). The responsible German body involved in its preparation was the Working Committee NA 041-01-56 AA "Solaranlagen" ("Solar systems") of the Standards Committee Heating and Ventilation Technology (NHRS) at DIN Deutsches Institut für Normung e. V. (German Institute for Standardization).
