This standard sets up a laboratory measurement method to determine the impact noise reduction of a floor covering when laid on a standard concrete floor mock-up and excited by a standard tapping machine. The method is restricted to floorings, which transmit impact sound mainly "locally" into the floor, i.e. through the area close to the points of excitation, so that the size of the flooring specimen does not have an influence on the results. Examples for such floors are carpets, PVC floorings, laminate floorings (lightweight floating floors, parquet floorings?) and the like. The results only provide information about the noise radiated. A subjective classification of the quality of the floor coverings is not intended. The method is kept as close as possible to ISO 140-8 and yields similar results within the range of application. This standard provides the measurement method. Product test codes may contain further requirements concerning the specimens, such as temperature range, the number of test specimens or special mounting conditions.
