# Testmessunsicherheitsverhältnis

In einem Kalibrierverfahren handelt es sich bei dem Testmessunsicherheitsverhältnis (TUR) um das Verhältnis zwischen der Genauigkeitstoleranz des zu kalibrierenden Geräts und der Messunsicherheit des verwendeten Kalibrierstandards. (NCSL, Seite 2)
TUR = UUT\_Toleranz / STD\_unsicher
Das TUR muss durch identische Parameter und Einheiten für das zu kalibrierende Gerät (UUC) und den Kalibrierstandard berechnet werden. Wenn die Genauigkeitstoleranzen als Dezibel, Prozent oder als anderes Verhältnis angegeben werden, müssen sie in absolute Werte der Basismessungs-Einheiten umgerechnet werden. Hinweis: Die Messunsicherheit eines Messstandards ist nicht notwendigerweise mit ihrer Genauigkeitsangabe gleichzusetzen.
