Sets out a method for determining the thermal performance characteristic of all classes of solar collectors operating with liquid as the heat-transfer fluid. The thermal performance characteristic may be used to estimate collector performance when subjected to different ambient conditions and load requirements.

This standard sets out a method for determining the thermal performance characteristic of all classes of solar collectors operating with liquid as the heat-transfer fluid. This thermal performance characteristic may be used to estimate the performance of the collector when subjected to different ambient conditions and load requirements. It can also be used as a basis for rating different collectors.The test method described is intended for use on all types of collector, which transfer incident solar energy, as heat, to liquid passing through the collector.
