For process control in pharmaceutical production, the collection of measurement data directly in the process and indirectly in the process environment is of crucial importance for the quality of the end product. These measurements require reliable measuring equipment that generates valid measurement results. In order to create confidence in the recorded measurement results, the measuring equipment must be calibrated with suitable traceability. Each measuring point must be assessed with regard to the necessity and scope of calibration. The measuring point risk analysis is a helpful tool for this. The permissible deviations, measurement uncertainties and design-related measurement tolerances and accuracies are valuable parameters for evaluating the measuring point and assessing the requirements for the measuring equipment and calibration procedures. The presentation will discuss these topics in detail and clarify the interrelationships.
