IEC 60196:2009规定了标准频率。标准频率是单相和三相交流系统、船舶安装、交流牵引系统、工具和飞机所采用的频率。这种标准化仅限于10 000 Hz以下的频率。第二版取消并取代了1965年出版的第一版。这是一项技术性修订。主要的变化是取消了人造丝行业的标准频率。根据IEC指南108，其具有水平标准的状态。

IEC 60196:2009 specifies the standard frequencies. The standard frequencies are the frequencies to be adopted for single-phase and three-phase a.c. systems, for installations in ships, for a.c. traction systems, for tools and for aircraft. This standardization is limited to frequencies up to 10 000 Hz. This second edition cancels and replaces the first edition published in 1965. It constitutes a technical revision. The main change is the removal of the standard frequencies for the rayon industry. It has the status of a horizontal standard in accordance with IEC Guide 108.
