ISO 9459-5:2007 PDF Download

A standard called ISO 9459-5:2007 focuses on describing how solar residential water heating systems work. The standard offers instructions for performing in-situ, indoor, and outdoor laboratory tests. Without the need for intricate measurements on individual components or inside the system, the objective of these tests is to evaluate the overall performance of the systems.

The method for doing whole-system testing using a "black box" approach is described in the standard. This indicates that rather than diving into the individual measurements of the components, the emphasis is on analyzing the system as a whole. The standard also outlines how to handle and examine the measurement data that was gathered throughout the tests. To ensure uniformity and accuracy in reporting system performance, the standard also offers instructions on how to format the test report.
