3. commissioning definitions :
• Pre-commissioning A series of verification and activities which
verify function of a competent, or group of components executed
prior to commencing commissioning activities on the portion of the
facilities, the Purpose of which is to prepare the system/subsystem
to be ready for commissioning .
• Commissioning is defined as those function testing activities to be
performed on a multi discipline basis and to bring the system into a
state of RFSU.
