IEC 61260-3:2016描述了倍频程和分数倍频程滤波器的定期测试程序，这些滤波器的设计符合IEC 61260-1:2014中给出的1级或2级规范。本标准的目的是确保所有实验室以一致的方式进行定期试验。IEC 61260-3第一版（连同IEC 61260-1:2014和IEC 61260-2:2016）取消并取代了1995年发布的IEC 61260第一版及其2001年发布的修正案1。本版为技术修订版。

IEC 61260-3:2016 describes procedures for periodic testing of octave-band and fractional-octave-band filters that were designed to conform to the class 1 or class 2 specifications given in IEC 61260-1:2014. The aim of this standard is to ensure that periodic testing is performed in a consistent manner by all laboratories. This first edition of IEC 61260-3 (together with IEC 61260-1:2014 and IEC 61260-2:2016), cancels and replaces the first edition of IEC 61260 published in 1995 and its Amendment 1 published in 2001. This edition constitutes a technical revision.
