The DST method for solar domestic hot water systems - Research and development for ISO and CEN standards

The Dynamic System Test (DST) method for performance characterization of solar domestic hot water (SDHW) systems has been the subject of international research for a number of years. At present, several countries are using the method and it is being standardized on international and European levels. This paper describes the state-of-the-art of research on the DST method and the activities planned to bring it to the level of a fully validated, standardized test method
