除IEC 61326-1的范围外，IEC 61326的本部分规定了更详细的试验 本协议所涵盖设备的配置、运行条件和性能标准 IEC 61326-1:2020附录A: -用于测试、测量或监测低压环境中的保护措施 配电系统，以及由电池供电和/或由测量电路供电，并且-便携式。 此类EUT的示例包括但不限于电压检测器、绝缘测试仪、， 接地连续性测试仪、接地电阻测试仪、泄漏电流钳、回路阻抗 测试仪、“剩余电流装置测试仪”（RCD测试仪）和相序测试仪 IEC 61557（所有部分）中定义。购买本文件时可获得的所有当前修订均包含在购买本文件中。

In addition to the scope of IEC 61326-1, this part of IEC 61326 specifies more detailed test configurations, operational conditions and performance criteria for equipment covered by Annex A of IEC 61326-1:2020 which is: — used for testing, measuring or monitoring of protective measures in low-voltage distribution systems, and;— powered by battery and/or from the circuit measured, and— portable. Examples of such EUTs include, but are not limited to, voltage detectors, insulation testers, earth continuity testers, earth resistance testers, leakage current clamps, loop impedance testers, "residual-current-device-testers" (RCD-testers) and phase sequence testers as defined in IEC 61557 (all parts).All current amendments available at time of purchase are included with the purchase of this document.
