Measurement procedures for materials used in photovoltaic modules - Encapsulants. Test procedure of optical durability Ingestion-build-797691 Scope IEC 612152 provides a set of qualification tests that indicate that a PV module design is likely to be free of flaws that will result in early failure. However, IEC 612152 does not address the long term wear out of PV modules. This part of IEC 627881 is designed as a more rigorous qualification test, using accelerated UV exposure at elevated temperature to determine whether polymeric encapsulants can suffer loss of optical transmittance.
