Hi all friends, the clause is described as: The monitoring system, at each CCP and for each OPRP, shall consist of documented information, including:
c)applicable calibration methods or, for OPRPs, equivalent methods for verification of reliable measurements or observations (see 8.7);
As we know, the measuring equipment that monitored OPRP shall be calibrated. However, If the monitoring method is to use observation (seeing, smelling, touching...), how can I address to "equivalent methods for verification of reliable measurements or observations "? Best Regards, avn165cwf
