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. 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.

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 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 concentrating collectors; thermal performance testing as given in EN 12975-2:2006, subclause 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. 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 2 m2. 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 document specifies performance test methods for control equipment. Furthermore this document contains requirements on accuracy, durability and reliability of control equipment. The tests described in CEN/TS 12977-5 are limited to components delivered with or for the system by the final supplier. For the purposes of this document (CEN/TS 12977-5) controller and control equipment for solar heating systems and auxiliary heaters, if part of the system, are restricted to: a) Controllers as 1) system clocks, timers and counters, 2) differential thermostats, 3) multi-function controllers. b) Sensors as 1) temperature sensors, 2) irradiance sensors (for short wave radiation), 3) pressure sensors, 4) level sensors, 5) flow meters or 6) heat meters. c) Actuators as 1) pumps, 2) solenoid and motor valves or 3) relays. Furthermore combinations of controllers, sensors and actuators listed above. An additional objective of the procedures described in this document is to verify control algorithms and, together with the accuracy of sensors, to determine control parameters. In addition to verifying the functioning of a controller, its equipment and actuators, the determined parameters may be used for numerical system simulations. Typically electrical anodes are not part of the control equipment and are not controlled by the control equipment. However, because they are electrical appliance, electrical anodes are included in this document. This document is valid for control equipment of solar heating systems for the purpose of hot water preparation and/or space heating. If the solar system is connected to or part of a conventional heating system, the validity is extended to the entire system.
