60051-1 © IEC:1997– 7 –INTERNATIONAL ELECTROTECHNICAL COMMISSION_________DIRECT ACTING INDICATING ANALOGUE ELECTRICAL MEASURINGINSTRUMENTS AND THEIR ACCESSORIES –Part 1: Definitions and general requirements common to all partsFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical reports or guides and they are accepted by the National Committees in that sense.4)In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60051-1 has been prepared by IEC technical committee 85:Measuring equipment for electromagnetic quantities.This fifth edition cancels and replaces the fourth edition published in 1984, amendment 1(1994) and amendment 2 (1995). It constitutes a technical revision.The text of this standard is based on the fourth edition, amendment 1, amendment 2 and thefollowing documents:FDISReport on voting85/166/FDIS85/177/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.SIST EN 60051-1:2000
60051-1 © IEC:1997– 9 –INTRODUCTIONIEC 60051 is published in separate parts according to the following structure and under thegeneral title Direct acting indicating analogue electrical measuring instruments and theiraccessories.Part 1:Definitions and General Requirements Common to all Pans.Part 2:Special Requirements for Ammeters and Voltmeters.Part 3:Special Requirements for Wattmeters and Varmeters.Part 4:Special Requirements for Frequency Meters.Part 5:Special Requirements for Phase Meters, Power Factor Meters and Synchroscopes.Part 6:Special Requirements for Ohmmeters (Impedance Meters) and Conductance Meters.Part 7:Special Requirements for Multi-function Instruments.Part 8:Special Requirements for Accessories.Part 9:Recommended Test Methods.Parts 2 to 9 are not complete in themselves and shall be read in conjunction with this Part 1.All of these pans are arranged in the same format and a standard relationship between subjectand clause number is maintained throughout. In addition, tables, figures and annexes add asuffix to the part number in order to differentiate the pans. This re-arrangement will assist thereader of IEC 60051 to distinguish information relating to the different types of instruments.SIST EN 60051-1:2000
60051-1 © IEC:1997– 11 –DIRECT ACTING INDICATING ANALOGUE ELECTRICAL MEASURINGINSTRUMENTS AND THEIR ACCESSORIES –Part 1: Definitions and general requirements common to all parts1 General1.1 ScopeThis standard applies to direct acting indicating electrical measuring instruments having ananalogue display, such as:–ammeters and voltmeters;–wattmeters and varmeters;–frequency meters of pointer and vibrating-reed types;–phasemeters, power-factor meters and synchroscopes;–ohmmeters, impedance meters and conductance meters;–multi-function instruments of the above types.It also applies to certain accessories used with these instruments, such as:–shunts;–series resistors and impedance elements.If other accessories are associated with instruments, this standard is applicable to thecombination of the instrument and the accessory provided that the adjustments have beenmade for the combination.This standard also applies to a direct acting indicating electrical measuring instrument whosescale marks do not correspond directly to its electrical input quantity, provided that therelationship between them is known.This standard also applies to instruments and accessories having electronic devices in theirmeasuring and/or auxiliary circuits.This standard does not apply to special purpose instruments which are covered by their ownIEC standards.This standard does not apply to special purpose devices which are covered by their own IECstandards when they are used as accessories.This standard does not contain either requirements for protection against environmentalconditions or the relevant tests. However, when necessary, and then only by agreementbetween the manufacturer and the user, tests to approximate the conditions of use may beselected from IEC 60068.This standard does not specify requirements concerning dimensions of instruments oraccessories (for the former, see IEC 60473).SIST EN 60051-1:2000
