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 themal storage unit is an integral part of the collector to such an extent,that the collection process cannot be separated from the stotage process for the purpose of making measurements of these two processes.It is not applicable to tracking concentrating solar collectors.
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)connot be tested in their actual form for durability,reliability and themal perfomance 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 2m*2m.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 static of the collector.
