  • Calibration reference standards / calibration equipment shall be traceable to national standards and be accompanied by certificates of traceability / analysis

  • If recognized standards are not available, an independent reproducible standard may be used

  • The calibration tolerance of a given standard should be as tight or tighter than the tolerance of the instrument to be calibrated

  • A procedure must be in place to ensure tracking and monitoring of standard’s expiration date and re-calibration / re-certification requirements
