220.127.116.11 Water System Qualification 水系统确认
Operational checks of all components of the water system should be performed using calibrated monitoring instruments including conductivity meters, temperature-sensing devices, pressure-sensing devices, and flow meters . Temperatures in loops and storage tanks, as well as during sanitization or steam sterilization procedures, should be monitored. Performance qualification should include intense monitoring of all use points on the system as well as other key sites including the incoming potable water source, feed water to the still, the still outlet, and storage tanks. The water quality following each pretreatment and purification step should also be monitored. After the initial performance qualification, a routine monitoring schedule should be established for all of these components . Routine monitoring of the water system is discussed in more detail in Section 9.7.
