Outline of Functional Qualification Test
By evaluating the influence of environmental conditions and reflecting this in the design and manufacturing of the active valve, it performs safety-related functions without damaging the valve under any conditions during the installation life of the active valve, it is a series of actions to prove, document, and maintain operability in accordance with ASME QME-1(KEPIC MFC) to meet the performance requirements of the system, and the environmental conditions are as follows.
- Temperature, pressure, humidity, radiation, electromagnetic waves, vibration, etc.
- Earthquake, natural environment and design-based accidents
