ISO 28927-7:2009规定了一种实验室方法，用于测量手持式电动啃齿机和剪切机手柄处的手传振动发射。这是一种型式试验程序，用于确定在规定试验条件下运行的机器夹紧区域的振动幅度。其目的是将结果用于比较同一类型机器的不同型号。 ISO 28927-7:2009适用于气动或其他方式驱动的用于切割金属板或复合材料的咬边机和剪切机。

ISO 28927-7:2009 specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held, power-driven nibblers and shears. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine run under specified test conditions. It is intended that the results be used to compare different models of the same type of machine. ISO 28927-7:2009 is applicable to nibblers and shears, driven pneumatically or by other means, intended for cutting sheet metal or composite materials.
