Måleusikkerhedsangivelse

Måleusikkerhedsangivelse refers to the statement or indication of the uncertainty associated with a measurement. In metrology and scientific practice, no measurement is perfectly exact. There will always be some degree of doubt or variability in the result obtained. Måleusikkerhedsangivelse quantifies this doubt.

It is typically expressed as a range around the measured value, indicating that the true value of the quantity being measured is expected to lie within this range with a certain level of confidence. This range is often presented as a numerical value, for example, 10.5 ± 0.2 mm, where 0.2 mm is the uncertainty.

The importance of måleusikkerhedsangivelse lies in its ability to provide a realistic assessment of the quality and reliability of a measurement. It allows users of the measurement to understand the potential errors and limitations, and to make informed decisions based on the data. It is a fundamental concept in ensuring comparability and traceability of measurements across different laboratories and industries. Standards like ISO 17025 emphasize the requirement for accredited laboratories to provide uncertainty statements for their calibration and testing results.
