62 FOREWORD
63 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
64 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
65 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
66 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
67 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
68 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
69 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
70 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
71 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
72 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
73 consensus of opinion on the relevant subjects since each technical committee has representation from all
74 interested IEC National Committees.
75 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
76 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
77 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
78 misinterpretation by any end user.
79 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
80 transparently to the maximum extent possible in their national and regional publications. Any divergence between
81 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
82 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
83 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
84 services carried out by independent certification bodies.
85 6) All users should ensure that they have the latest edition of this publication.
86 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
87 members of its technical committees and IEC National Committees for any personal injury, property damage or
88 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
89 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
90 Publications.
91 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
92 indispensable for the correct application of this publication.
93 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
94 rights. IEC shall not be held responsible for identifying any or all such patent rights.
95 IEC 81355-1 has been prepared by IEC technical committee 3: Documentation, graphical
96 symbols and representations of technical information, in close cooperation with ISO technical
97 committee 10: Technical product documentation. It is an International Standard.
98 It is published as a double logo standard and has the status of a horizontal publication in
99 accordance with IEC Guide 108.
100 This edition cancels and replaces the second edition of IEC 61355-1 published in 2008. This
101 edition constitutes a technical revision.

131 INTRODUCTION
132 Information is necessary for all activities during the life cycle of a system, e.g., information
133 about industrial plants, constructions, technical installations, and equipment. Information may
134 be received from and delivered to stakeholders of the system of interest. Different stakeholders
135 may need different information or different views on the same system, depending on what is
136 most suitable for their current need.
137 This document is based on former IEC 61355:2008 and IEC 61355DB, but as a new joint ISO
138 & IEC document, it introduces a shift in mindset: from document code classes (known as “DCC”)
139 to classification of information in a broad sense, represented by information class codes (ICC).
140 These are used to unambiguously identify information conveyed among parties.
141 Because of this shift in mindset from documentation (IEC 61355) to information (this document),
142 it is acknowledged that a document can contain and present more than one type of information.
143 For humans to interpret information, the information is always presented in a certain form such
144 as e.g., a text, a drawing, or a 3D model. In this document, information about an object is always
145 conveyed in an information container which shall be identified by an unambiguous designation.
146 When the information container is under revision control, it is defined as a document.
147 One aim of this document is to establish a method for unambiguous communication and
148 understanding between parties involved in information interchange. To get a basis for a system,
149 it is necessary to disregard what information (and subsequently the documentation presenting
150 the information) is called in daily life. Instead, the basis for a common understanding shall be
151 an information kind classification, which is based only on the content of information provided.
152 Thus, the user of this document needs to disregard the view of a document as “a piece of
153 paper”, instead seeing it as an analogue or digital container which conveys information.
154 Another aim of this document is to set up rules for a specific method of correlating information
155 and objects, i.e., to indicate to which object or system a specific information belongs. For this
156 purpose, an information designation system is provided, linking the information kind designation
157 to the object designation used for the system of interest. By that, guidance is also given for
158 sorting and grouping as well as for structured information search, for example in information
159 storage systems and for identification of information containers, e.g., as file names.

169 1 Scope
170 This part of the 81355 International Standard, published jointly by IEC and ISO, provides rules
171 and guidelines for the classification and designation of information based on its inherent
172 content. This document is applicable for information used in the life cycle of a system, e.g.,
173 industrial plants, construction entities and equipment.
174 This document defines classes of information and their codes (Information Class Code – ICC).
175 The defined classes and codes provided are intended to be used as values associated with
176 metadata, e.g., in information management systems (see IEC 82045-1 and IEC 82045-2).
177 The rules, guidelines and classes are general and are applicable to all technical areas, for
178 example mechanical engineering, electrical engineering, construction engineering and process
179 engineering. They can be used for systems based on different technologies or for systems
180 combining several technologies.
181 This document is also a horizontal publication intended for use by technical committees in
182 preparation of publications related to classification and designation of information in accordance
183 with the principles laid down in IEC Guide 108.

277 Information is necessary for different activities and purposes during the life cycle of a system.
278 Sender and receiver of any information related to a system of interest are the stakeholders of
279 the system.
280 Information is often transmitted using specific terms, serving different purposes. These terms
281 are often defined and understood only in a certain context, which can lead to misunderstandings
282 for the recipient of the information.

283 To handle large amounts of information, this document provides a classification scheme to
284 structure and subsequently sort the type of information in groups, each characterised by an
285 unambiguous definition in a clear type-of hierarchy. The user of this document can link self-
286 developed, unknown, and non-included information terms by relating the new term to the class
287 defining the kind of information and thereby expand the use and application of this document.
288 Annex A shows the information model of the concept of this document.

304 4.2 Classification principles
305 This document defines hierarchical classes of information based on what the information is
306 about in itself, as distinct from what a user wishes to convey with the information.
307 Each group within the hierarchy has a letter code which designate the class and its subclass.
308 This letter code is called an Information Class Code, which in this document is abbreviated
309 “ICC”. As the ICC is recognized by non-verbatim letter codes (A, B, C etc.), the ICC itself
310 becomes a natural designation for recognition of information across national borders,
311 languages, and technical disciplines, thus creating a common language for exchange of
312 information.
313 NOTE 1 The former Document kind Classification Code (“DCC”) from IEC 61355 is in this document replaced by
314 “ICC”, as the aim of this standard is to classify information in a broad sense, as distinct from documentation
315 presenting the information in a certain form only. However, the meaning behind former DCC codes is to the extent
316 possible transferred to ICC codes in this document. See also Annex D.
317 The classification scheme defined in Annex B has a hierarchical structure that constitutes two
318 levels L1 and L2, where:
319 • entry classes (L1) are purely defined based on the inherent content of information; and
320 • subclasses (L2) of the entry classes are based on different facets, depending on the entry
321 class.
322 Annex B specifies ICC entry classes (table B.1) and sub-classes (table B.2).
323 NOTE 2 Classes of information presented in this document are considered to be complete and fully representative
324 for information related to technical systems, and therefore no “miscellaneous” or “other” open classes, “free for the
325 user” etc., is provided. See also Annex D.2.
326 Information shall be associated with a main class and a related subclass when its inherent
327 content matches the definitions of a main-class and a subclass. See Annex B, Table B.1 for
328 main class and Table B.2 for subclass definitions.
329 5 Designation of information containers
330 5.1 General
331 An information shall be associated with a class of information (ICC) to which it belongs, as
332 defined in table B.1 and B.2 (see annex B). To classify information correctly, the information to
333 be classified shall comply with the definition of the ICC selected.
334 The information container designation shall designate the information container unambiguously
335 within a defined context. The information container designation shall;
