1 Scope
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).
NOTE Particular EMC requirements for equipment covered by IEC 61557‑8 and IEC 61557‑9 are given in IEC 61326‑2‑4.
The manufacturer specifies the environment for which the product is intended to be used and/or selects the appropriate test level specifications of IEC 61326‑1.
