According to ISO 9001 or DIN ISO 17025, measurement and test equipment must be regularly calibrated. The resulting calibration certificates issued by the calibration laboratory in accordance with DIN 51309 or VDI/VDE 2646:2019 are valid for 26 months. After this period, the equipment must be recalibrated if the risk of incorrect measurements is to be reduced and costs for recalls or rework are to be avoided.
Every sensor and the associated measuring chain are subject to a variety of influences that can affect the measuring accuracy, such as aging, wear, operating errors, overloading, external or internal damage. Therefore, depending on the measuring principle, accuracy requirements, and risk analysis, measuring instruments must be calibrated at regular intervals or after an event such as an accident or misuse. We will be pleased to advise you when a calibration is useful or necessary.
