IEC TS 62600-4:2020 specifies the requirements of the technology qualification process for marine renewable technologies. Technology Qualification is a process of providing evidence and arguments to support claims that the technology under assessment will function reliably in a target operating environment within specific limits and with an acceptable level of confidence.
The Technology Qualification process is also assumed in IEC TS 62600-2:2019.
