Measurement procedures for materials used in photovoltaic modules - Encapsulants. Test procedure of optical durabilityWhat is BS EN IEC 6278817 about? BS EN IEC 6278817 is a part of a multi series standard that deals with the performance qualifications of materials used in photovoltaic modules. BS EN IEC 6278817 is designed as a more rigorous qualification test, using accelerated UV exposure at elevated temperature to determine whether polymeric encapsulants can suffer the loss of optical transmittance. BS EN IEC 6278817 gives specifications for test procedures such

- defines the architectural relationship with other ISO geographic information standards
