Mittaustodistus

Mittaustodistus, often translated as "measurement certificate" or "calibration certificate," is a document that provides evidence of the accuracy and traceability of a measurement. It is issued by a calibration laboratory or a metrology institute following a calibration process. The certificate details the results of the calibration, including the measured values, the associated uncertainties, and the conditions under which the measurement was performed. It also typically includes information about the measuring instrument being calibrated, its identification number, the calibration date, and the date of the next recommended calibration.

A key aspect of a mittaustodistus is traceability. This means that the measurement results can be related to national or international standards through an unbroken chain of comparisons, each with a stated uncertainty. This traceability ensures that the instrument's performance is comparable to other instruments and standards worldwide. The uncertainty statement is crucial as it quantifies the doubt associated with the measurement result, indicating the range within which the true value is likely to lie.

Mittaustodistus is essential for quality assurance and regulatory compliance in various industries. It provides confidence in the reliability of measurements used in production, research, development, and product testing. For example, in manufacturing, accurate measurements are vital for ensuring product quality and safety. In the scientific field, precise measurements are fundamental for the validity of experimental results. Regulatory bodies often require calibrated instruments with valid mittaustodistus to demonstrate compliance with specific standards and directives.
