This part of ISO 16251 specifies a laboratory measurement method to determine the improvement of impact sound insulation by a floor covering when laid on a standard concrete floor mock-up and excited by a standard tapping machine. The method is restricted to soft, flexible floor coverings, 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 floor coverings, and linoleum. These floor coverings correspond to ‘category I’ of ISO 10140-1, Annex H. 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 10140 and yields the same results within the range of uncertainty and within the range of application. This part of ISO 16251 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.
