round robin test

Part of the requirements for carrying the FGW conformity seal is the participation in all future FGW robin tests. These tests are used to ensure quality assurance for the application of FGW guidelines and to determine ambiguities and uncertainties. For this purpose, the participating institutes apply the entire or parts of the testing method on identical sample data sets, simulation models or devices. The submitted results are compared with each other and examined against pre-defined success criteria. If the success criteria are adhered to, the participation in the round robin test is considered  as passed.

Current Round Robin Tests

Description: The round robin test aims to check the reproducibility of data analysis of sound emission measurements according to IEC 61400-11 ed. 3. Raw measurement data provided by the participants is used as a basis. The following points are tested:


  • Data reduction and classification
  • Determination and processing of acoustic measurands
  • Determination of correction values
  • Determination of tonality
  • Determination of measurement uncertainties


Based on the evaluation and discussion of the results, the quality of the standard shall be checked. Furthermore, the results can serve as a proof for the qualification of the participating test laboratories.
