IEC 62037-2:20 21定义了测量同轴电缆组件产生的无源互调水平的程序。本试验方法适用于跨接电缆，即用于在刚性设备之间提供接口柔性的电缆组件。它还用于评估在运行中受到运动的电缆组件。 第二版取消并取代了2012年出版的第一版。与上一版相比，此版本包括以下重大技术变更: a.机械应力的应用标准修订为公布的电缆弯曲半径的函数。

IEC 62037-2:2021 defines a procedure to measure levels of passive intermodulation generated by a coaxial cable assembly. This test method is applicable to jumper cables, i.e. cable assemblies intended to provide interface flexibility between rigid devices. It is also used to evaluate cable assemblies that are subjected to motion in operation.
This second edition cancels and replaces the first edition published in 2012. This edition includes the following significant technical changes with respect to the previous edition:
a. criteria for application of mechanical stress revised to be a function of advertised cable bend radius.
