FOREWORD

The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this 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 “IEC Publication(s)”). 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. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies.
All users should ensure that they have the latest edition of this publication.
No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication.
Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60050‑871 has been prepared by IEC SyC AAL: Active Assisted Living, under the responsibility of IEC technical committee 1: Terminology.

This first edition has the status of a horizontal standard in accordance with IEC Guide 108.

The text of this standard is based on the following documents:

Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

In this part of the IEV, the terms and definitions are provided in French and English; in addition the terms are given in Arabic (ar), German (de), Spanish (es), Italian (it), Japanese (ja), Polish (pl), Portuguese (pt) and Chinese (zh).

A list of all parts of the IEC 60050 series, published under the general title International Electrotechnical Vocabulary, can be found on the IEC website and is available at www.electropedia.org.

INTRODUCTION

Principles and rules followed

General

The IEV (IEC 60050, International Electrotechnical Vocabulary) is a general purpose multilingual vocabulary covering the field of electrotechnology, electronics and telecommunication (available at www.electropedia.org). It comprises about 22 000 terminological entries, each corresponding to a concept. These terminological entries are distributed among about 90 parts, each part corresponding to a given field.

Part 161 (IEC 60050‑161): Electromagnetic compatibility
Part 411 (IEC 60050‑411): Rotating machines

The terminological entries follow a hierarchical classification scheme part/section/concept; within the sections, the terminological entries are organized in a systematic order.

The terms and definitions (and possibly non-verbal representations, examples, notes to entry and sources) in the entries are given in two or more of the three IEC languages, that is to say French, English and Russian (principal IEV languages).

Information regarding the IEV and the drafting and presentation of the terminological entries is provided in the IEC Supplement to the ISO/IEC Directives, Annex SJ. The following constitutes a summary of these rules.

Organization of a terminological entry

Each of the terminological entries corresponds to a concept, and comprises:

an IEV number,
possibly a letter symbol for the quantity or unit,

then, for the principal IEV languages present in the part:

the term designating the concept, called “preferred term”, possibly accompanied by synonyms and abbreviations,
the definition of the concept,
possibly non-verbal representations, examples and notes to entry,
possibly the source,

and finally, for the additional IEV languages, the terms alone.

IEV number

The IEV number is comprised of three elements, separated by hyphens:

part number: 3 digits,
section number: 2 digits,
entry number: sequence of decimal digits in which leading zeroes are permissible but redundant (e.g. 1 to 113, 01 to 99, 001 to 127).

EXAMPLE 845-27-003

Letter symbols for quantities and units

These symbols, which are language independent, are given on a separate line following the IEV number.

131-12-04
R
resistance

Preferred term and synonyms

The preferred term is the term that heads a terminological entry in a given language; it can be followed by synonyms. It is printed in boldface.

Synonyms:

The synonyms are printed on separate lines under the preferred term: preferred synonyms are printed in boldface, admitted and deprecated synonyms are printed in lightface. Deprecated synonyms are prefixed by the text “DEPRECATED:”.

Absence of an appropriate term:

When no appropriate term exists in a given language, the preferred term is replaced by five dots, as follows:

“ ” (and there are of course no synonyms).

Attributes

Each term (and synonym) can be followed by attributes giving additional information, and printed in lightface on the same line as the corresponding term, following this term.

specific use of the term:
- transmission line, <in electric power systems>
national variant:
- lift, GB
grammatical information:
- quantize, verb
- transient, noun
- AC, adj

Source

In some cases, it has been necessary to include in an IEV part a concept taken from another IEV part, or from another authoritative terminology document (ISO/IEC Guide 99, ISO/IEC 2382, etc.), either with or without modification to the definition (and possibly to the term).

This is indicated by the mention of this source, printed in lightface, and placed at the end of the terminological entry in each of the principal IEV languages present.

EXAMPLE SOURCE: IEC 60050‑131:2002, 131-03-13, modified

Terms in additional IEV languages

These terms are placed following the terminological entries in the principal IEV languages, on separate lines (a single line for each language), preceded by the alpha-2 code for the language defined in ISO 639‑1, and in the alphabetic order of this code.

1 Scope

This part of IEC 60050 gives the general terminology used in active assisted living, as well as general terms pertaining to specific applications and associated technologies. It has the status of a horizontal standard in accordance with IEC Guide 108, Guidelines for ensuring the coherency of IEC publications – Application of horizontal standards.

This terminology is consistent with the terminology developed in the other specialized parts of the IEV.

This horizontal standard is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108.

One of the responsibilities of a technical committee is, wherever applicable, to make use of horizontal standards in the preparation of its publications.
