BS EN 61260-3:2016描述了倍频带和倍频带的定期测试程序 分数倍频程滤波器，其设计符合1级或2级 IEC 61260-1:2014中给出的规范。本标准的目的是确保定期 所有实验室均以一致的方式进行测试。定期测试的目的是向用户保证倍频带的性能 分数倍频程带滤波器符合IEC 61260的适用规范- 1适用于有限的一组关键试验，以及进行试验的环境条件 都被执行了。本标准中的试验范围故意限制在最低限度 被认为是定期测试所必需的。本标准中所述的定期试验适用于制造商要求的过滤器 声称符合IEC 61260-1:2014中的规范。本标准中的定期试验 适用于型号已获得或未获得制造商批准的型号的过滤器 独立的测试机构，负责根据测试进行模式批准 IEC 61260-2的程序。由于定期试验的范围有限，如果没有型式认证的证据 可公开获取，没有关于符合规范的一般结论 即使定期试验的结果符合所有适用标准，也可以制定IEC 61260-1 本标准的要求。交叉引用:IEC 61260-1:2014EN 61260-1:2014IEC 61260-2:2016EN 61260-2:2016IEC 61672-1EN 61672-1ISO/IEC指南98-3GUM:1995ISO/IEC指南98-4购买本文件时提供的所有当前修订版均包括在内。

BS EN 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.The purpose of periodic testing is to assure the user that the performance of an octaveband and fractional-octave-band filter conforms to the applicable specifications of IEC 61260- 1 for a limited set of key tests and for the environmental conditions under which the tests were performed.The extent of the tests in this standard is deliberately restricted to the minimum considered necessary for periodic tests.Periodic tests described in this standard apply to filters for which the manufacturer claims conformance to the specifications in IEC 61260-1:2014. Periodic tests in this standard apply to filters for which the model has been, or has not been, pattern approved by an independent testing organization responsible for pattern approvals in accordance with the test procedures of IEC 61260-2.Because of the limited extent of the periodic tests, if evidence of pattern approval is not publicly available, no general conclusion about conformance to the specifications of IEC 61260-1 can be made, even if the results of the periodic tests conform to all applicable requirements of this standard.Cross References:IEC 61260-1:2014EN 61260-1:2014IEC 61260-2:2016EN 61260-2:2016IEC 61672-1EN 61672-1ISO/IEC Guide 98-3GUM:1995ISO/IEC Guide 98-4All current amendments available at time of purchase are included with the purchase of this document.
