During a compliance audit for a pharmaceutical production line, we encountered an inexplicable discrepancy in pressure sensor readings. The calibration protocol found on Teknonorm was decisive. We applied the step-by-step procedure for verifying the traceability of secondary standards. Not only did we identify a 0.3% drift in the supplier's internal standard, but we were able to document the entire correction process in accordance with SR EN ISO/IEC 17025.
The resources on measurement uncertainty and management of metrological records allowed us to present a complete report to the regulatory authority, avoiding any delay in the line's approval. The accuracy and clarity of the information are exceptional.
