This International Standard specifies test methods for assessing the durability, reliability and safety for fluid heating collectors. This International Standard also includes test methods for the thermal performance characterization of fluid heating collectors, namely steady-state and quasi-dynamic thermal performance of glazed and unglazed liquid heating solar collectors and steady-state thermal performance of glazed and unglazed air heating solar collectors (open to ambient as well as closed loop). This International Standard is also applicable to hybrid collectors generating heat and electric power. However it does not cover electrical safety or other specific properties related to electric power generation. This International Standard is also applicable to collectors using external power sources for normal operation and/or safety purposes. This International Standard 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. This document (EN ISO 9806:2013) has been prepared by Technical Committee ISO/TC 180 "Solar energy" in collaboration with Technical Committee CEN/TC 312 "Thermal solar systems and components" (secretariat: ELOT, Greece). The responsible German body is Working Committee NA 041-01-56 AA "Solaranlagen (SpA CEN/TC 312 und ISO/TC 180)" ("Solar systems (SpA CEN/TC 312 und ISO/TC 180)") of the DIN Standards Committee Heating and Ventilation Technology and their Safety (NHRS).
