Test clauses with remark of are subcontracted to qualified subcontractors and descripted under the respective test clause in the report. Deviations of testing specification(s) or customer requirements are listed in specific test clause in the report. 4 Die Entscheidungsregel fü r Konformitä tserklä rungen basierend auf numerischen Messergebnisen in diesem Prü fbericht basiert auf der "Null-Grenzwert-Regel" und der "Einfachen Akzeptanz" gemä ß ILAC G8:2019 und

IEC Guide 115:2021, es sei denn, in der auf Seite 1 dieses Berichts genannten angewandten Norm ist etwas anderes festgelegt oder vom Kunden gewü nscht. Dies bedeutet, dass die Messunsicherheit nicht berü cksichtigt wird und daher auch nicht im Prü fbericht angegeben wird. Zu weiteren Informationen bezueglich des Risikos durch diese Entscheidungsregel siehe ILAC G8:2019.

The decision rule for statements of conformity, based on numerical measurement results, in this test report is based on the “Zero Guard Band Rule” and “Simple Acceptance” in accordance with ILAC G8:2019 and IEC Guide 115:2021, unless otherwise specified in the applied standard mentioned on Page 1 of this report or requested by the customer. This means that measurement uncertainty is not taken in account and hence also not declared in the test report. For additional information to the resulting risk based of this decision rule please refer to ILAC G8:2019.www.tuv.com
