The ISO 22975 series covers solar collector components and materials. ISO 22975-5 is one of the parts of a series that specifies the requirements on insulation materials for solar collectors and test methods for durability and performance of insulation materials used in solar collectors.
ISO 22975-5 is applicable to all types of insulation material used in solar collectors, such as rigid polyurethane foam (PU), phenolic foam (PF), mineral wool (MW) and mineral fibre.
ISO 22975-5 on solar energy is applicable to:
The insulation material is a component of a solar collector that is employed as a thermal insulation element and is inserted behind the panel in a flat plate solar collector or in the header of an evacuated tube solar collector through a specific filling procedure.
ISO 22975-5 helps in the improved performance of solar collectors by providing test methods for measuring the common properties of insulation materials, including apparent density, the apparent volume percentage of open cells of PU and PF, and dimension, bulk density of MW, and mineral fibre.
ISO 22975-5 helps in improvement in durability of insulation materials by providing test methods for compression properties, water absorption, hygroscopic sorption properties, water vapor transmission properties, flammability, accelerated aged value of thermal resistance of PU and PF, and compression behaviour, water absorption, moisture content, water vapor transmission properties, maximum use temperature, non-combustibility of MW and mineral fibre.
Compliance with test methods provided by ISO 22975-5 can help you demonstrate quality, reliability and durability of solar connectors while minimizing risks of product failure.
