Auswahl des Kalibrierdienstleisters: Wie die Kalibrierunsicherheit Ihre Prüfgenauigkeit und Ihr Risiko beeinflusst
Jede Messung weist einen gewissen Grad an Variabilität auf – und das Ausmaß dieser Variabilität bestimmt das Risiko, das Sie tragen. Die Kalibrierunsicherheit beeinflusst die Genauigkeit Ihrer Prüfergebnisse, die Einhaltung von Prüfnormen und die Qualität der von Ihnen versandten Produkte. Dieser Beitrag ergänzt die gleichnamige Videoserie von Instron und erklärt, was Kalibrierunsicherheit ist, wie man die tatsächlichen Aussagen eines Kalibrierscheins bewertet und worauf man bei der Auswahl eines Dienstleisters achten sollte – einschließlich Akkreditierungsumfang, veröffentlichter Unsicherheitswerte und der Art und Weise, wie Pass/Fail-Entscheidungen getroffen werden.
