Kalibrierstandard

A Kalibrierstandard, or calibration standard, is a physical object or a precisely defined substance used to establish a reference point for measurements. Its primary purpose is to ensure accuracy and consistency in measuring instruments and systems. When an instrument is calibrated, its readings are compared against a Kalibrierstandard. If the readings deviate from the standard, the instrument is adjusted to correct the discrepancy. This process is crucial in many fields, including science, engineering, manufacturing, and healthcare.

Kalibrierstandards can take various forms depending on the quantity being measured. For length measurements, a gauge block might serve as a standard. For temperature, a precisely controlled oven or a known melting point substance can be used. In electrical measurements, a voltage or resistance standard is employed. For chemical analysis, a certified reference material with a known concentration of a specific analyte acts as the standard.

The reliability of a Kalibrierstandard is paramount. It must be traceable to national or international measurement standards to ensure its accuracy and comparability across different laboratories and regions. Calibration standards themselves are periodically verified and calibrated to maintain their accuracy over time. The use of accurate Kalibrierstandards underpins the validity of scientific research, the quality of manufactured goods, and the safety of medical diagnoses.
