Solar Collector Testing (ISO 9806)

Scope: The Standard establishes methods for determining the thermal performance of glazed liquid heating solar collectors. It provides test methods and calculation procedures for determining the steady-state thermal performance of solar collectors. It contains methods for conducting tests outdoors under natural solar irradiance. It is not applicable to those collectors in which the thermal storage unit is an integral part of the collector to such an extent that the collection process cannot be separated for the purpose of making measurements of these two processes. Specific test are:

• Steady-state efficiency test
• Determination of the pressure drop curve
• Determination of the effective thermal capacity
• Determination of the time constant
• Determination of the incidence angle modifier
• Internal pressure test for metallic absorbers
• High-temperature resistance test
• Exposure test
• External thermal shock test
• Internal thermal shock test
• Rain penetration test
• Mechanical load tests
• Energy Output Proof for Solar Collector (without accreditation)
