This European Standard applies to newly manufactured electromechanical watt-hour meters intended for residential, commercial and light industrial use, of class indexes A and B, for the measurement of alternating current electrical active energy in 50Hz networks. It specifies particular requirements and type test methods.It applies to electromechanical watt-hour meters for indoor and outdoor application, consisting of a measuring element and register(s) enclosed together in a meter case. It also applies to operation indicator(s) and test output(s).If the meter has (a) measuring element(s) for more than one type of energy (multi-energy meters), or when other functional elements, like maximum demand indicators, electronic tariff registers, time switches, ripple control receivers, data communication interfaces etc. are enclosed in the meter case (multi-function meters) then this standard applies only for the active energy metering part.This standard distinguishes between:meters of class indexes A and B;direct connected and transformer operated meters;meters for use in networks equipped with or without earth fault neutralizers.It does not apply to:watt-hour meters where the voltage across the connection terminals exceeds 600V (line-to-line voltage for meters for polyphase systems);portable meters.The safety aspect is covered by EN62052‑31:2016.Regarding acceptance tests see EN62058‑11:20andEN62058‑21:20.
