Messunsicherheits
Messunsicherheit, also known as measurement uncertainty, refers to the doubt or lack of confidence in the results of a measurement. It is a fundamental concept in metrology, the science of measurement, and is used to quantify the reliability of measurement results. Measurement uncertainty arises from various sources, including instrumental limitations, environmental factors, and the inherent variability of the measured quantity.
There are two main types of measurement uncertainty: Type A and Type B. Type A uncertainty is
The overall measurement uncertainty is typically expressed as an expanded uncertainty, which is the combined standard
Understanding and quantifying measurement uncertainty is crucial for ensuring the validity and reliability of measurement results.
