ISO 16251-1:2014规定了一种实验室测量方法，以确定在标准混凝土地板模型上铺设地板覆盖物并通过标准敲击机激发时，地板覆盖物对冲击隔音的改善。该方法仅限于柔软、灵活的地板覆盖物，其主要通过靠近激发点的区域将冲击声“局部”传递到地板中，因此地板样本的尺寸不会对结果产生影响。例如地毯、PVC和油毡。这些地板覆盖物符合ISO 10140-1:2010附录H第一类的要求。 结果仅提供有关辐射噪声的信息。不打算对地板覆盖物的质量进行主观分类。 ISO 16251-1:2014提供了测量方法。产品测试代码可以包含有关试样的进一步要求，例如温度范围、试样数量或特殊安装条件。

ISO 16251-1:2014 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 of such floor coverings are carpets, PVC, and linoleum. These floor coverings correspond to ISO 10140？1:2010, Annex H, category I. The results only provide information about the noise radiated. A subjective classification of the quality of the floor coverings is not intended. ISO 16251-1:2014 provides the measurement method. Product test codes can contain further requirements concerning the specimens, such as temperature range, the number of test specimens or special mounting conditions.
