and interactive services that specify requirements for the Hybrid Fibre Coax (HFC) Outside Plant (OSP) Power Supplies (PS)

This part of ISO 15548 does not give the extent of verification nor acceptance criteria for the characteristics

Because prescriptive regulations covering fire-safety design will co-exist for some time with performance-based design

If a reference PV device or a thermopile type detector is used to measure the irradiance

The IEC 60904 series is a European Standard that covers various requirements, test conditions of photovoltaic devices. BS EN 60904 5 is the fifth part of the EN 60904 series that specifies the preferred method for determining the equivalent cell temperature (ECT) of PV devices for the purposes of comparing their thermal characteristics, determining NOCT (nominal operating cell
