Messkontinuität

Messkontinuität, translated as measurement continuity, is a concept in metrology and measurement science that refers to the preservation of measurement traceability and accuracy over time, across different measuring instruments, or between different measurement processes. It ensures that a series of measurements, even if performed at different times or with different equipment, can be reliably compared and considered as part of a single, coherent measurement chain.

The core idea behind Messkontinuität is to maintain an unbroken link back to a primary standard. This is achieved through a hierarchical system of calibration, where each measuring instrument is calibrated against a reference standard of higher accuracy, which in turn is calibrated against an even higher standard, ultimately leading to a national or international standard. This chain of calibrations ensures that the measurement results are consistent and comparable.

Maintaining Messkontinuität is crucial for quality control, regulatory compliance, and scientific research. It allows for the reliable tracking of changes in a measured quantity, the comparison of results from different laboratories or industries, and the validation of product specifications. Without Messkontinuität, measurement results could be arbitrary, leading to incorrect decisions, product failures, and a lack of trust in scientific data. Processes like regular calibration, use of certified reference materials, and adherence to standardized measurement procedures are essential for establishing and maintaining measurement continuity.
