33、rs”, being used indoors and outdoors in large quantities worldwide. It does not deal with special implementations (such as metering-part and/or displays in separate housings). This standard is intended to be used in conjunction with the appropriate part of IEC 62053 for the type of equipment under c
34、onsideration. This standard distinguishes between meters intended to be used indoors and outdoors; and protective class I and protective class II meters. The test levels are regarded as minimum values to guarantee the proper functioning of the meter under normal working conditions. For special appli

36、type tests for electricity metering equipment for indoor and outdoor application and applies to newly manufactured equipment designed to measure the electrical energy on 50 Hz or 60 Hz networks, with a voltage up to 600 V. It applies to electromechanical or static meters for indoor and outdoor appli
37、cation 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 for more than one type of energy (multi-energy meters), or when other functional elements, such as maximum de
38、mand indicators, electronic tariff registers, time switches, ripple control receivers, data communication interfaces, etc. are enclosed in the meter case, then the relevant standards for these elements apply. It does not apply to: a) portable meters; b) data interfaces to the register of the meter;
39、c) reference meters. For rack-mounted meters, the mechanical properties are not covered in this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
