Flexible cellular polymeric materials. Determination of resilience by ball rebound Ingestion-build-207047 This document may be applicable

This document may be applicable to PV devices designed for use under concentrated irradiation if they are measured without the optics for concentration and irradiated using direct normal irradiance and a mismatch correction with respect to a direct normal reference spectral irradiance distribution is performed

which is due to the phase difference between the voltage and current at the fundamental frequency

BS 8215:1991

Note: BS EN 16790 does not apply to caves
