Nuclear power plants - Instrumentation and control systems important to safety - Cable connector assemblies for harsh environment purposes
Scope: IEC 63423:2026 applies to cable connector assemblies for harsh environment purposes that are important to safety. It covers the engineering safety aspects to be met in the design, qualification, fabrication, assembling, testing, and installation on site of cable connector assemblies to be operated under accident conditions.
This document can be additionally used for cable assemblies that are operated under normal conditions.
This document covers cable connector assemblies that are used for the following generic functions:
- signal transmission (AC or DC voltage/current; pulses, frequency), or
- supplying electrical energy to sensors, transducers, or other devices.
