This part of IEC 61 753 specifies the test requirements for wavelength selective cords used in a controlled environment (category C) according to IEC 61 753-1 :201 8, where the connectors already comply with the category C requirements of IEC 61 753-1 :201 8. The tests selected are a subset of the connector tests from IEC 61 753-1 :201 8 appropriate for requalification with additional requirements relevant to cords and the connector/cable interface.
