IEC 61260-1:20 14规定了带通滤波器的模拟、采样数据和数字实现的性能要求。滤波器的相对衰减特性的通带区域的范围是给定带宽的所有滤波器的确切中带频率的恒定百分比。符合本标准要求的仪器可以包含覆盖任何所需频率范围的任意数量的连续带通滤波器。提供了两种过滤器类别的性能要求:1类和2类。一般来说，1类和2类过滤器的规格具有相同的设计目标，主要在验收限值和工作温度范围方面有所不同。2类的验收限度大于或等于1类的验收限度。最大值-还规定了允许的扩展测量不确定度。符合本标准性能要求的带通滤波器可以是各种测量系统的一部分，也可以是频谱分析仪等特定仪器的组成部分。本标准规定了过滤器运行的环境条件范围。所需的范围取决于包含过滤器的仪器是设计成在受控环境中操作还是更一般地在现场操作。符合本标准要求的带通滤波器能够为各种各样的信号提供频带滤波的频谱信息，例如时变的、间歇的或稳定的信号；宽带或离散频率；以及长或短的持续时间。第一版IEC 61260-1、未来的IEC 61260-2和未来的IEC 61260-3取消并取代第一版IEC 61260(1995)及其修正案1(2001)。本版本为技术修订版，包括与IEC 61260（1995）及其修正案1（2001）相关的以下重大技术变更: -IEC 61260（1995）第一版及其修正案1（2001）中的单一文件在IEC 61260系列中分为三个部分，涵盖:规范、模式评估试验和定期试验； -性能类别class 0被移除； -规范的设计目标可以仅基于基数-10； -参考环境条件已从20℃/65%RH改变为23℃/50%RH；和 -IEC 61260（1995）规定了公差限值，但没有考虑用于验证规范的测量不确定度。IEC 61260系列规定了实验室测试是否符合标准规范的观测值和最大允许测量不确定度的验收限值。

IEC 61260-1:2014 specifies performance requirements for analogue, sampled-data, and digital implementations of band-pass filters. The extent of the pass-band region of a filter's relative attenuation characteristic is a constant percentage of the exact mid-band frequency for all filters of a given bandwidth. An instrument conforming to the requirements of this standard may contain any number of contiguous band-pass filters covering any desired frequency range. Performance requirements are provided for two filter classes: class 1 and class 2. In general, specifications for class 1 and class 2 filters have the same design goals and differ mainly in the acceptance limits and the range of operational temperature. Acceptance limits for class 2 are greater than, or equal to, those for class 1. Maximum-permitted expanded uncertainties of measurement are also specified. Band-pass filters conforming to the performance requirements of this standard may be part of various measurement systems or may be an integral component of a specific instrument such as a spectrum analyser. This standard specifies the ranges of environmental conditions for operation of the filters. The required range depends on whether the instrument containing the filters is designed to be operated in a controlled environment or more generally in the field. Band-pass filters conforming to the requirements of this standard are capable of providing frequency-band-filtered spectral information for a wide variety of signals, for example, time-varying, intermittent or steady; broadband or discrete frequency; and long or short durations. This first edition of IEC 61260-1, future IEC 61260-2 and future IEC 61260-3, cancel and replace the first edition of IEC 61260 (1995) and its amendment 1 (2001). This edition constitutes a technical revision which includes the following significant technical changes with respect to the IEC 61260 (1995) and its amendment 1 (2001):
- the single document in the first edition of IEC 61260 (1995) and its amendment 1 (2001) is in IEC 61260 series separated into the three parts covering: specifications, pattern evaluation tests and periodic tests;
- the performance category class 0 is removed;
- the design goals for the specification can be based only base-10;
- the reference environmental conditions have been changed from 20 °C / 65 % RH to 23 °C / 50 % RH; and
- IEC 61260 (1995) specified tolerance limits without considering the uncertainty of measurement for verification of the specifications. IEC 61260 series specifies acceptance limits for the observed values and maximum-permitted uncertainty of measurements for laboratories testing conformance to specifications in the standard.
