Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation.
The IEC collaborates closely with the International Organization for Standardization ISO in accordance with conditions determined by agreement between the two organizations. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. The IEC shall not be held responsible for identifying any or all such patent rights. Equipment for electrical energy measurement and load control. The text of this standard is based on the following documents: The committee has decided that the contents of this publication will remain unchanged until Electromechanical meters for active energy classes 0,5, 1 and 2 Replaces particular requirements of IEC Static meters for active energy classes 1 and 2 Replaces particular requirements of IEC Static meters for reactive energy classes 2 and 3 Replaces particular requirements of IEC Pulse output devices for electromechanical and electronic meters two wires only IEC Power consumption and voltage requirements IEC General concepts IEC Collection of meter dependability data from the field This part is a standard for type testing electricity meters.
This standard is intended to be used in conjunction with the appropriate part of IEC for the type of equipment under consideration. 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.
INTERNATIONAL STANDARD IEC 62052-11
For special application, other test levels might be necessary and should be agreed upon between the user and the manufacturer. Metering equipment 1 Scope This part of IEC covers 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 V. It applies to electromechanical or static 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 6252 for more than one type of energy multi-energy metersor when other functional elements, such as maximum demand indicators, electronic tariff registers, time switches, ripple control receivers, data communication interfaces, etc. Isc does not apply to: For rack-mounted meters, the mechanical properties are not covered in this standard.

Plastic and ebonite 3 Terms and definitions For the purposes of this International Standard, the following definitions apply.
Expression of the performance of electrical and electronic measuring equipment has been taken from IEC Where there is a difference between the definitions 622052 the glossary and those contained in product standards produced by TC 13, then the latter shall take precedence in applications of the relevant standard.
NOTE Standards for reactive power apply for sinusoidal currents and voltages containing the fundamental frequency only.

The type may have several values of reference current and reference voltage. Each type has one designation only. NOTE 1 The type is represented by the sample meter s intended for the type tests, whose characteristics reference current and reference voltage are chosen from the values given in the tables proposed by the manufacturer.
NOTE 2 Where the number of ampere-turns would lead to a number of turns other than a whole number, the product of the number of turns of the windings by the value of the basic current may differ from that of the sample meter s representative of the type.
It is advisable to choose the next iecc immediately above or below in order to have whole numbers of turns. NOTE 3 The ratio of the highest to the 6052 basic speed of the rotors of each of the meters of the same type shall not exceed 1,5.
Meters are designated by the manufacturer by one or more groups of letters or numbers, or a combination of letters and numbers. NOTE The type is represented by the sample meter s intended for the type tests, whose characteristics reference current and reference voltage are chosen from the values given in the ied proposed by the manufacturer. It is usually designed and operated to obtain the highest accuracy and stability in a controlled laboratory environment 3.
A single electronic display may be used with multiple electronic memories to form multiple electronic registers. For a flush-mounted meter, the meter base may include the sides of the case. It may be a single-position socket for one meter or a multipleposition socket for two or more meters 3. It ice comprise several layers which ice be tested singly as supplementary or basic iiec. The distortion factor is usually expressed as a percentage 3.
For this range, relaxed accuracy requirements may be specified 3. It generally comprises electromagnets with their control devices. It comprises one or more magnets and their adjusting devices. When the meter eic operated from a current transformer sattention is drawn to the need to match the current 662052 of the meter in relation to that of the secondary of the current transformer s. The maximum current of the meter is 1,2 I n1,5 I n or 2 I n.
All parts which are subject to corrosion under normal working conditions shall be protected effectively. Any protective coating shall not be liable to damage by ordinary handling nor damage due to exposure to air, under normal working conditions. Outdoor meters shall withstand solar radiation.
NOTE For meters for special use in corrosive atmospheres, additional requirements shall be fixed in the purchase contract for example salt mist test according to IEC The cover shall not be removable without the use of iiec tool. The case shall be so constructed and arranged that any non-permanent deformation cannot prevent the satisfactory operation of the meter. The mechanical strength of the meter case shall be tested with the following tests:
