INTERNATIONAL ELECTROTECHNICAL COMMISSION ____________
INDUSTRIAL SYSTEMS, INSTALLATIONS AND EQUIPMENT AND INDUSTRIAL PRODUCTS –
STRUCTURING PRINCIPLES AND REFERENCE DESIGNATIONS –
Part 2: Classification of objects and codes for classes
FOREWORD 1) 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.
2) 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.
3) 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.
4) 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.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment 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 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) andexpenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) 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.
9) 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 81346-2 has been prepared by IEC technical committee 3: Information structures, documentation and graphical symbols and ISO technical committee 10: Technical product documentation.
It is published as a double logo standard.
This edition cancels and replaces the first edition of IEC 61346-2, published in 2000 and the first edition of IEC/PAS 62400, published in 2005.
This edition includes the following technical changes with respect to IEC 61346-2 Ed.1:
• all rules concerning the application of letter codes have been removed as these should be included in another publication dealing with the application of letter codes within reference designations;
and, with respect to IEC/PAS 62400 Ed.1:

INTERNATIONAL ELEKTROTEKNISK KOMITE____________
INDUSTRIANLÆG, INSTALLATIONEROG UDSTYR SAMT INDUSTRIPRODUKTER –
PRINCIPPER FOR STRUKTURER OG REFERENCEBETEGNELSER –
Del 2: Klassifikation af objekter og koder for klasser
FORORD1) Den internationale elektrotekniske kommission (IEC) er en verdensomspændende standardiseringsorganisation, som om-
fatter alle nationale elektrotekniske komitéer (IEC-nationalkomitéer). IEC's formål er at fremme internationalt samarbejde vedrørende alle spørgsmål, som angår standardisering på det elektriske og elektroniske område. Til dette formål foruden til andre aktiviteter udgiver IEC internationale standarder, tekniske specifikationer, tekniske rapporter, offentligt tilgængelige rapporter (PAS) og vejledninger (herefter benævnt IEC-publikationer). Publikationerne udarbejdes af tekniske komitéer. En-hver national IEC-komité, som er interesseret i et emne, har ret til at deltage i publikationsudarbejdelsen. Internationale or-ganisationer – både statslige og ikke-statslige – der har en samarbejdsaftale med IEC, deltager ligeledes i arbejdet. IEC samarbejder tæt med ISO (International Organization for Standardization) i overensstemmelse med betingelser vedtaget af de to organisationer.
2) IEC's formelle beslutninger eller aftaler på tekniske områder udtrykker, så tæt på som det er muligt, en international konsen-sus på de relevante emner, fordi hver tekniske komité har repræsentanter fra alle interesserede nationalkomitéer.
3) IEC-publikationer er udformet som anbefalinger til international anvendelse og er accepteret af IEC-nationalkomitéerne som sådan. Al den stund, der ydes alle rimelige anstrengelser for at sikre, at det tekniske indhold i IEC-publikationer er nøj-agtigt, kan IEC ikke holdes ansvarlig for den måde, hvorpå det bliver anvendt, eller for enhver misfortolkning af nogen slut-bruger.
4) For at fremme den internationale ensartethed forpligter IEC's nationalkomitéer sig til at anvende IEC-publikationer i størst mulig udstrækning på en let genkendelig måde i deres nationale og regionale publikationer. Enhver afvigelse mellem en IEC-publikation og den tilsvarende nationale eller regionale publikation skal angives tydeligt i sidstnævnte.
5) IEC giver ikke nogen mærkningsanvisning til indikation af godkendelse og kan ikke drages til ansvar for, om en udstyrsde-klaration er i overensstemmelse med en IEC-publikation.
6) Alle brugere bør sikre sig, at de har den seneste udgave af denne publikation.
7) Intet erstatningsansvar kan pålægges IEC eller dens direktører, ansatte, assistenter eller agenter, herunder individuelle eks-perter og medlemmer af dens tekniske komitéer samt IEC’s nationalkomitéer, for enhver personskade, beskadigelse af ejendom eller anden beskadigelse af hvilken som helst natur, hverken direkte eller indirekte, eller for omkostninger (inkl. advokatbistand) og udgifter i forbindelse med publikationen, anvendelse af eller tiltro til denne IEC-publikation eller enhver anden IEC-publikation.
8) Opmærksomheden henledes på de normative referencer, der er angivet i denne publikation. Anvendelse af de refererede publikationer er obligatoriske for korrekt anvendelse af denne publikation.
9) Opmærksomheden henledes på den mulighed, at nogle af bestanddelene i denne IEC-publikation kan gøres til genstand for patentrettigheder. IEC kan ikke drages til ansvar for at identificere sådanne rettigheder.
International standard IEC 81346-2 er udarbejdet af teknisk komité 3: Informationsstrukturer, dokumentation og gra-fiske symboler i tæt samarbejde med ISO's tekniske komité 10: Teknisk produktdokumentation.
Den er udgivet som en dobbeltlogostandard.
Denne udgave erstatter den første udgave af IEC 61346-2 udgivet i 2000 og den første udgave af IEC/PAS 62400 ud-givet i 2005.
Denne udgave indeholder følgende tekniske ændringer i forhold til IEC 61346-2, 1. udgave:
der omhandler anvendelsen af bogstavkoder i referencebetegnelser.
Med henvisning til IEC/PAS 62400, 1. udgave:

– 6 – 81346-2 IEC:2009
INTRODUCTION
0.1 General
The aim of this part of IEC 81346 is to establish classification schemes for objects with associated letter codes which can be applied throughout all technical areas, e.g. electrical, mechanical and civil engineering as well as all branches of industry, e.g. energy, chemical industry, building technology, shipbuilding and marine technology. The letter codes are intended for use with the rules for the construction of reference designations in accordance with IEC 81346-1.
Annex A illustrates how objects may be classified according to their intended purpose or task related to a generic process.
Annex B illustrates how objects may be classified according to their position in an infrastructure.
0.2 Basic requirements for this standard
The basic requirements were developed during the preparation of IEC 61346-2 Ed. 1, and accepted by vote by the national committees.
NOTE These basic requirements concern the development of the letter code classification system in this standard and not its application. They are therefore not normative vis-à-vis the application of this standard.
(1) Letter codes shall be based on a classification scheme. (2) A classification scheme is the set of definitions for the types of objects (for example, a
classification scheme for function types containing the definition of the different function types of objects).
(3) A classification scheme shall allow for hierarchical classification of types of objects, i.e. subclasses and superclasses.
(4) A letter code for a type of object shall be independent of the actual position of the instances of that type of object in a system.
(5) Distinct classes shall be defined on each level of the classification scheme. (6) The definitions of the classes of a particular level within a classification scheme shall
have a common basis (for example, a classification scheme that, on one level, classifies objects according to colour shall not contain classes that classify objects by shape). The basis, however, may vary from one level to another.
(7) A letter code should indicate the type of object and not an aspect of this object. (8) A classification scheme shall allow for expansion in order to take into account future
development and needs. (9) A classification scheme shall be usable within all technical areas without favouring a
specific area. (10) It shall be possible to use the letter codes consistently throughout all technical areas.
The same type of object should preferably have only one letter code independent of the technical area where it is being used.
(11) It should be possible to indicate in a letter code from which technical area the object originates, if this is wanted.
(12) A classification scheme should reflect the practical application of letter codes. (13) Letter codes should not be mnemonic, as this cannot be implemented consistently
throughout a classification scheme and for different languages. (14) Letter codes shall be formed using capital letters from the Latin alphabet, excluding I
and O due to possible confusion with the digits 1 (one) and 0 (zero).

INDLEDNING
0.1 Generelt
Formålet med denne del af IEC 81346 er at fastlægge klassifikationsplaner for objekter med tilhørende bogstavko-der, der kan anvendes overalt i alle tekniske områder, fx elektriske og mekaniske områder og byggekonstruktions-områder samt alle grene af industrien, fx energiindustri, kemisk industri, byggeteknologi, skibsbyggeri og marine-teknologi. Bogstavkoderne er beregnet til brug sammen med reglerne for udarbejdelsen af referencebetegnelser i overensstemmelse med IEC 81346-1.
Anneks A viser, hvordan objekter kan klassificeres i overensstemmelse med deres formål eller opgave i relation til en generisk proces.
Anneks B viser, hvordan objekter kan klassificeres i overensstemmelse med deres placering i infrastrukturen.
0.2 Basiskrav i denne standard
Basiskravene blev udviklet under udarbejdelsen af IEC 61346-2, 1. udgave, og blev vedtaget af de nationale komitéer gennem afstemning.
NOTE – Disse basiskrav vedrører udviklingen af bogstavkoder til klassifikation i denne standard og ikke deres anvendelse. De er derfor ikke normative i forhold til anvendelsen af denne standard.
1) Bogstavkoder skal baseres på en klassifikationsplan.
2) En klassifikationsplan er et sæt af definitioner for typerne af objekter (fx en klassifikationsplan til funktioner, der indeholder forskellige typer af funktioner til objekterne).
3) En klassifikationsplan skal tillade en hierarkisk klassifikation af typer, dvs. underklasser og overklasser.
4) En bogstavkode for en objekttype skal være uafhængig af den aktuelle position af de forekomster af den sam-me bestemte type af objekter i et system.
5) Særskilte klasser skal defineres på hvert niveau i klassifikationsplanen.
6) Definitionerne af klasser for et bestemt niveau inden for en klassifikationsplan skal have et fælles grundlag (fx: en klassifikationsplan, der på ét niveau klassificerer objekter i henhold til farve, skal ikke indeholde klasser, der klassificerer objekter efter form). Grundlaget kan imidlertid variere fra et niveau til et andet.
7) En bogstavkode bør indikere typen af objektet og ikke aspektet til objektet.
8) En klassifikationsplan skal tillade udvidelser for at kunne imødekomme fremtidige udvidelser og behov.
9) En klassifikationsplan skal kunne anvendes inden for alle tekniske områder uden at favorisere et bestemt om-råde.
10) Det skal være muligt at anvende bogstavkoder konsekvent i alle tekniske områder. Den samme objekttype bør fortrinsvis kun have én bogstavkode uafhængigt af det tekniske område, som den anvendes i.
11) Såfremt det ønskes, bør det i bogstavkoden være muligt at angive, hvilket teknisk område objektet stammer fra.
12) En klassifikationsplan bør reflektere den praktiske anvendelse af bogstavkoder.
13) Bogstavkoder bør ikke være mnemotekniske, da disse ikke kan implementeres konsekvent på tværs af klassifi-kationsplaner og i forskellige sprog.
14) Bogstavkoder skal udformes ved hjælp af store bogstaver fra det latinske alfabet, eksklusive I og O, da disse kan forveksles med tallene 1 (et) og 0 (nul).

(15) Different classification schemes shall be allowed and be applicable for the same type of object.
(16) Objects may be classified for example according to function types, shapes, colours, or material. This means that the same type of object may be assigned different letter codes according to the different classification schemes.
(17) Objects that are directly constituents of another object using the same aspect shall be assigned letter codes according to the same classification scheme as shown in Figure 1. See also Figure A.1.
Objects 2, 3, and 4, which are direct constituents of object 1, shall be assigned letter codes from the same classification scheme.
Objects 5 and 6, which are direct constituents of object 2, shall be assigned letter codes from the same classification scheme.
Objects 7 and 8, which are direct constituents of object 4, shall be assigned letter codes from the same classification scheme.
Objects 9, 10, 11, and 12, which are direct constituents of object 6, shall be assigned letter codes from the same classification scheme.
Objecst 13, 14, 15, and 16, which are direct constituents of object 8, shall be assigned letter codes from the same classification scheme.

15) Forskellige klassifikationsplaner tillades og skal kunne anvendes for den samme objekttype.
16) Objekter kan fx klassificeres i overensstemmelse med funktionstyper, form, farver eller materiale. Dette bety-der, at den samme objekttype kan tildeles flere forskellige bogstavkoder i overensstemmelse med forskellige klassifikationsplaner.
17) Objekter, der er direkte bestanddele af et andet objekt, som anvender det samme aspekt, skal bruge den sam-me klassifikationsplan som vist i figur 1. Se også figur A.1.
Objekt 2, 3 og 4, som er direkte bestanddele af objekt 1, skal tildeles bogstavkoder fra den samme klassifikationsplan.
Objekt 5 og 6, som er direkte bestanddele af objekt 2, skal tildeles bogstavkoder fra den samme klassifikationsplan.
Objekt 7 og 8, som er direkte bestanddele af objekt 4, skal tildeles bogstavkoder fra den samme klassifikationsplan.
Objekt 8, 10, 11 og 12, som er direkte bestanddele af objekt 6, skal tildeles bogstavkoder fra den samme klassifikationsplan.
Objekt 13, 14, 15 og 16, som er direkte bestanddele af objekt 8, skal tildeles bogstavkoder fra den samme klassifikationsplan.

4 Klassifikationsprincipper
4.1 Generelt
Princippet for klassifikation af objekter er baseret på at betragte hvert objekt som en måde at udføre en aktivitet på ofte med et input og et output (se figur 2). I den forbindelse er den interne struktur af et objekt ikke vigtigt.
