60447 © IEC:2004– 5 –INTERNATIONAL ELECTROTECHNICAL COMMISSION____________BASIC AND SAFETY PRINCIPLES FOR MAN-MACHINE INTERFACE,MARKING AND IDENTIFICATION –ACTUATING PRINCIPLESFOREWORD1)The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications,Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IECPublication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interestedin 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. IEC collaborates closelywith the International Organization for Standardization (ISO) in accordance with conditions determined byagreement between the two organizations.2)The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an internationalconsensus of opinion on the relevant subjects since each technical committee has representation from allinterested IEC National Committees.3)IEC Publications have the form of recommendations for international use and are accepted by IEC NationalCommittees in that sense. While all reasonable efforts are made to ensure that the technical content of IECPublications is accurate, IEC cannot be held responsible for the way in which they are used or for anymisinterpretation by any end user.4)In order to promote international uniformity, IEC National Committees undertake to apply IEC Publicationstransparently to the maximum extent possible in their national and regional publications. Any divergencebetween any IEC Publication and the corresponding national or regional publication shall be clearly indicated inthe latter.5)IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with an IEC Publication.6)All users should ensure that they have the latest edition of this publication.7)No liability shall attach to IEC or its directors, employees, servants or agents including individual experts andmembers of its technical committees and IEC National Committees for any personal injury, property damage orother damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) andexpenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IECPublications.8)Attention is drawn to the Normative references cited in this publication. Use of the referenced publications isindispensable for the correct application of this publication.9)Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject ofpatent rights. IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60447 has been prepared by IEC technical committee 16: Basicand safety principles for man-machine interface, marking and identification.This third edition cancels and replaces the second edition published in 1993 and constitutes atechnical revision.This edition includes the following significant technical changes with respect to the previousedition:a) special national conditions have been revised editorially;b) requirements concerning rotating actuators have been added;c) requirements concerning work with display screen equipment have been added.It has the status of a basic safety publication in accordance with IEC Guide 104.

60447 © IEC:2004– 7 –The text of this standard is based on the following documents:FDISReport on voting16/419/FDIS16/420/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.The committee has decided that the contents of this publication will remain unchanged until2008. At this date, the publication will be• reconfirmed;• withdrawn;• replaced by a revised edition, or• amended.

60447 © IEC:2004– 9 –INTRODUCTIONThis basic safety publication is intended for use by technical committees in the preparation ofstandards; it is not intended to be used on its own except in the absence of such standards.Where no safety consideration is involved, the relevant technical committee may permitspecific exclusions within the framework of this basic safety publication, and according to therules given in IEC Guide 104 and ISO/IEC Guide 51.Different kinds of actuators enable electrical equipment and processes to be operated andmaintained under normal and fault conditions.In modern equipment, the moving of an actuator in a certain direction is only one method ofactuation. In addition, actuators or data input devices arranged in the form of function oralphanumeric keyboards, or other kinds of actuator (e.g. light pen, touch sensitive screen,mouse), are in general use for computerized equipment.Actuators as a part of the man-machine interface may have a different importance in thedialogue between the operator and the equipment or machine.Standardization is especially important where safety is concerned (e.g. where an incorrectactuation may cause damage, or where a frequent or rapid actuation is necessary, such as inthe operation of cranes or transport vehicles), and is particularly necessary in the case ofequipment likely to be operated by unskilled persons.Ergonomic aspects should also be taken into account.

60447 © IEC:2004– 11 –BASIC AND SAFETY PRINCIPLES FOR MAN-MACHINE INTERFACE,MARKING AND IDENTIFICATION –ACTUATING PRINCIPLES1 ScopeThis International Standard establishes general actuating principles for manually operatedactuators forming part of the man-machine interface associated with electrical equipment, inorder to:–increase the safety (e.g. of persons, property, environment) through the safe operation ofthe equipment;–facilitate the proper and timely operation of the actuators.These principles apply, not only for the operation of electrical equipment, machines, orcomplete plant under normal conditions, but also under fault or emergency conditions.This standard is for general application, from simple cases such as single actuators (e.g.push-buttons) to multiple actuators, forming

part of a large assembly of electrical and non-electrical equipment, or

part of a central process control station.This standard establishes correlations between the function of an actuator and its direction ofactuating or location in relation to other actuators.In the absence of particular rules, this standard may also be applied to actuators operated bya part of the human body other than the hand (e.g. to foot-operated devices).2 Normative referencesThe following referenced documents are indispensable for the application of this document.For dated references, only the edition cited applies.
