ISO 22000 requires
1) Who should define the frequency of calibration? a) The manufacturer of equipment b) The organization c) Outside laboratory (third party) 2) Should verification process determine if equipment is out of tolerance before the time of the certificate expiration? I think the answer is "yes" and ISO 22000 prescribes:
8.3 Control of monitoring and measuring The organization shall provide evidence that the specified monitoring and measuring methods and equipment are adequate to ensure the performance of the monitoring and measuring procedures. Where necessary to ensure valid results, the measuring equipment and methods used a) shall be calibrated or verified at specified intervals, or prior to use, against measurement standards traceable to international or national measurement standards; where no such standards exist, the basis used for calibration or verification shall be recorded, b) shall be adjusted or re-adjusted as necessary, c) shall be identified to enable the calibration status to be determined, d) shall be safeguarded from adjustments that would invalidate the measurement results, and e) shall be protected from damage and deterioration. Records of the results of calibration and verification shall be maintained.
And if the appropriate action is "recalibration" and doesn’t fall any of the options (a to d). <BR><BR>3) If we prefer to do the calibration internally, can certificate of master gauge suffice, or the personnel who will do the calibration should be certified by a authorized body?
8.4.2 If verification does not demonstrate conformity with the planned arrangements, the organization shall take action to achieve the required conformity. Such action shall include, but is not limited to, review of a) existing procedures and communication channels (see 5.6 and 7.7), b) the conclusions of the hazard analysis (see 7.4), the established operational PRP(s) (see 7.5) and the HACCP plan (see 7.6.1), c) the PRP(s) (see 7.2), and d) the effectiveness of human resource management and of training activities (see 6.2).
