Defines a procedure for measurement of the acoustic properties of floor coverings from the view-point of reduction of impact noise transmission. Defines a procedure for determination of the noise reducing value of a floor covering under standard test conditions. This test is limited to the definition of methods for the physical measurement of sound originating from an artificial source (standard tapping machine) under laboratory conditions and is not directly related to the subjective significance of the results. Applies to all floor coverings, both single- or multi-layered, as installed on a standard floor. Multi-layered coverings can be factory- or test-site- assembled. Does not provide for allowing the assessing of effectiveness of a floor covering in situ.
