Scope

This standard specifies the test methods for the steady-state and quasi-steady-state thermal performance of solar collectors under simulated solar radiation indoors. This standard applies to flat-plate solar collectors with pressure drop, transparent cover, and liquid heat transfer medium. This standard is also applicable to evacuated tube solar collectors. This standard does not apply to concentrating solar collectors, thermal storage solar collectors that integrate heat storage and collectors, nor does it apply to tracking solar collectors and solar collectors without cover plates.
