- Abstract:
- Measurement uncertainty undoubtedly plays a large role in the assessment of compliance with certain specifications. For example, the widely accepted ILAC G8:09/19 publication gives relatively flexible guidelines for assessing the conformity of certain instruments to their respective standards or specifications. On the other hand, the information given in calibration certificates is often interpreted too rigorously which can, unfortunately, lead to the false conclusion that the instrument in question doesn’t actually meet the client’s specified requirements. In the following paper we will examine the role measurement uncertainty has in the assessment of compliance with regards to specified tolerance limits for 5 different instruments: calipers, contact thermometers (at temperatures above 600 °C), hygrometers, temperature chambers (such as laboratory incubators or refrigerators) and piston pipettes.
