Solar energy. Collector components and materials - Absorber surface durability Ingestion-build-258901 BS EN 17141 sets out1 Scope This part of ISO 22975 is applicable to the determination of the long term behaviour and service life of selective solar absorbers for use in vented flat plate solar collectors working under conditions corresponding to that in a typical solar domestic hot water system or combisystem. This part of ISO 22975 specifies a failure criterion of a solar absorber based on changes in optical performance of the absorber. The optical properties of
