适用范围：This European Standard applies to newly manufactured watt-hour meters, measuring active electrical energy, intended for residential, commercial and light industrial use, for use on 50 Hz electricalnetworks. It specifies general requirements and type tests methods.It applies to electromechanical or static watt-hour meters for indoor and outdoor application, consisting of a measuring element and register(s) enclosed in a meter case. It also applies to operationindicator(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, timeswitches, 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:– electromechanical and static meters;– meters of class indexes A, B and C;– direct connected and transformer operated meters;– protective class I and protective class II meters;– meters intended to be used indoors and outdoors.It does not apply to:– watt-hour meters where the voltage across the connection terminals exceeds 600 V (line-to-linevoltage for meters for polyphase systems);– portable meters;– reference meters.For rack-mounted meters, the mechanical properties are not covered in this standard.The test levels are regarded as minimum values to guarantee the proper functioning of the meter under normal working conditions. For special applications, other test levels might be necessary andshould be agreed on between the user and the manufacturer.
