1 Scope
This standard specifies test methods and calculation procedures for the thermal performance of solar collector (hereinafter referred to as collector) in steady and dynamic state.
This standard is applicable to plate solar collector (hereinafter referred to as plate collector) heated by solar radiation and with transparent cover and liquid heat transfer working medium, non-light-concentrating all glass evacuated solar collector with liquidwhose heat transfer working medium is liquid, glass-metal evacuated tube solar collector and heat pipe evacuated tube solar collector (hereinafter referred to as evacuated tube collector).
This standard is not applicable to heat-storage solar collector integratinged with heat reservoir with and collector and is also not applicable to solar collector without transparent cover and tracing focus.
