Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.

ISO/IEC 9995-1:2006(E)
Introduction
In the years prior to the existence of lSO/IEC 9995 the keyboard layout of information technology equipment
(ITE) such as personal computers, workstations and computer terminals was determined by standards which
were originally intended for typewriters, adding machines and the like. This led to the fact that designers of
office machine keyboards had to choose from the sometimes inconsistent standards, which in turn led to the
existence of widely dissimilar keyboard layouts.
lSO/IEC 9995 defines a framework for the layout of keyboards for ITE. The functions to be performed by
keyboards are grouped into four categories that correspond to the four physical sections of the keyboard.
Application of lSO/IEC 9995 in the design of keyboards will provide the user with a unified, predictable
interface between the user and office machines by dividing the keyboard into functional areas and sections,
and allocating functions to keys. One of the major tasks is to accommodate the larger and/or multiple sets of
characters required by the various applications for which keyboards are used today. This was achieved by
permitting the allocation of more than one graphic character or control function to each of the keys of a
keyboard, predominantly in the alphanumeric section.

INTERNATIONAL STANDARD ISO/IEC 9995-1:2006(E)
Information technology — Keyboard layouts for text and office
systems —
Part 1:
General principles governing keyboard layouts
1 Scope
lSO/IEC 9995 specifies various characteristics of keyboards used by information technology equipment (ITE),
e.g.
a) personal computers, workstations, computer terminals, VDTs (visual display terminals), typewriters, etc.,
having an alphanumeric keyboard;
b) calculators, telephones and automated teller machines having a numeric keypad.
The keyboard defined in lSO/IEC 9995 is the conventional linear keyboard, which is physically divided into
sections and the sections into zones within which the keys are laid out.
In this part of lSO/IEC 9995, the sections of the keyboard are identified and the general shape and relative
placement of the sections are specified. Spacing of keys and physical characteristics are covered in this part
of lSO/IEC 9995, as are the principles governing the placement of characters and symbols on keys.
This part of ISO/IEC 9995 specifies a key numbering system which applies to all types of numeric,
alphanumeric and composite keyboards of ITE.
This part of lSO/IEC 9995 specifies the principles governing the placement of characters and symbols on keys
used on all types of numeric, alphanumeric and composite keyboards of ITE. Although the keyboard defined
by lSO/IEC 9995 may be used for different languages, the specifications are written as applying to Latin
languages with a character path from left to right and a line progression from top to bottom.
The primary layout within the alphanumeric zone is established in most countries by a national standard or by
national usage. Allocation guidelines are provided in lSO/IEC 9995-2. Complementary layouts are specified in
lSO/lEC 9995-3.
This part of lSO/IEC 9995 defines characteristics related to interface 1 in Figure 1.
lSO/IEC 9995 specifies the allocation of functions (graphic characters and/or control functions) to keys. The
graphic characters and the control functions have been given common names intended to be familiar to the
users of a keyboard. In general, keyboards are not expected to generate coded control functions, but the
operation of a control function key may cause a number of coded control functions to appear in data
interchange to achieve the desired effect.
The effects of those keys that affect keyboard states are specified in other parts of lSO/IEC 9995.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 9995-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 35, User interfaces.
This second edition cancels and replaces the first edition (ISO/IEC 9995-1:1994), which has been technically

ISO/IEC 9995-1:2006(E)
Introduction
In the years prior to the existence of lSO/IEC 9995 the keyboard layout of information technology equipment
(ITE) such as personal computers, workstations and computer terminals was determined by standards which
were originally intended for typewriters, adding machines and the like. This led to the fact that designers of
office machine keyboards had to choose from the sometimes inconsistent standards, which in turn led to the
existence of widely dissimilar keyboard layouts.
lSO/IEC 9995 defines a framework for the layout of keyboards for ITE. The functions to be performed by
keyboards are grouped into four categories that correspond to the four physical sections of the keyboard.
Application of lSO/IEC 9995 in the design of keyboards will provide the user with a unified, predictable
interface between the user and office machines by dividing the keyboard into functional areas and sections,
and allocating functions to keys. One of the major tasks is to accommodate the larger and/or multiple sets of
characters required by the various applications for which keyboards are used today. This was achieved by
permitting the allocation of more than one graphic character or control function to each of the keys of a
keyboard, predominantly in the alphanumeric section.

INTERNATIONAL STANDARD ISO/IEC 9995-1:2006(E)
Information technology — Keyboard layouts for text and office
systems —
Part 1:
General principles governing keyboard layouts
1 Scope
lSO/IEC 9995 specifies various characteristics of keyboards used by information technology equipment (ITE),
e.g.
a) personal computers, workstations, computer terminals, VDTs (visual display terminals), typewriters, etc.,
having an alphanumeric keyboard;
b) calculators, telephones and automated teller machines having a numeric keypad.
The keyboard defined in lSO/IEC 9995 is the conventional linear keyboard, which is physically divided into
sections and the sections into zones within which the keys are laid out.
In this part of lSO/IEC 9995, the sections of the keyboard are identified and the general shape and relative
placement of the sections are specified. Spacing of keys and physical characteristics are covered in this part
of lSO/IEC 9995, as are the principles governing the placement of characters and symbols on keys.
This part of ISO/IEC 9995 specifies a key numbering system which applies to all types of numeric,
alphanumeric and composite keyboards of ITE.
This part of lSO/IEC 9995 specifies the principles governing the placement of characters and symbols on keys
used on all types of numeric, alphanumeric and composite keyboards of ITE. Although the keyboard defined
by lSO/IEC 9995 may be used for different languages, the specifications are written as applying to Latin
languages with a character path from left to right and a line progression from top to bottom.
The primary layout within the alphanumeric zone is established in most countries by a national standard or by
national usage. Allocation guidelines are provided in lSO/IEC 9995-2. Complementary layouts are specified in
lSO/lEC 9995-3.
This part of lSO/IEC 9995 defines characteristics related to interface 1 in Figure 1.
lSO/IEC 9995 specifies the allocation of functions (graphic characters and/or control functions) to keys. The
graphic characters and the control functions have been given common names intended to be familiar to the
users of a keyboard. In general, keyboards are not expected to generate coded control functions, but the
operation of a control function key may cause a number of coded control functions to appear in data
interchange to achieve the desired effect.
The effects of those keys that affect keyboard states are specified in other parts of lSO/IEC 9995.

ISO/CEI 9995-1:2006(F)
Introduction
Avant l'existence de l'ISO/CEI 9995, la disposition des claviers des équipements informatiques comme les
ordinateurs personnels, les stations de travail et les terminaux d'ordinateurs, était régie par des normes
destinées initialement aux machines à écrire, aux calculatrices et autres. Les concepteurs de claviers de
machines de bureau ont donc dû choisir parmi les normes quelquefois incompatibles, qui à leur tour ont
donné lieu à l'existence de dispositions de clavier très différentes.
L'ISO/CEI 9995 définit une structure pour la disposition des claviers des équipements informatiques. Les
fonctions devant être exécutées par les claviers sont groupées en quatre catégories qui correspondent aux
quatre modules physiques du clavier.
L'application de l'ISO/CEI 9995 dans la conception des claviers va fournir une interface uniforme et prévisible
entre l'utilisateur et les machines de bureau en divisant le clavier en zones et modules, et en affectant des
fonctions aux touches. L'une des tâches principales a été de prendre en charge les jeux plus élaborés ou
multiples de caractères requis par les diverses applications auxquelles sont destinés les claviers de nos jours.
On est parvenu à ce résultat en affectant plusieurs caractères graphiques ou fonctions de commande à
chacune des touches d'un clavier, principalement dans le module alphanumérique.

Technologies de l'information — Disposition des claviers
conçus pour la bureautique —
Partie 1:
Principes généraux pour la disposition des claviers
1 Domaine d'application
L'ISO/CEI 9995 spécifie les différentes caractéristiques des claviers d'équipements informatiques, par
exemple
a) les ordinateurs personnels, les stations de travail, les terminaux d'ordinateurs, les terminaux à écran de
visualisation (TEV), les machines à écrire, etc., dotés d'un clavier alphanumérique, et
b) les calculatrices, les téléphones et les guichets automatiques qui possèdent un pavé numérique.
Le clavier défini dans l'ISO/CEI 9995 est de type linéaire courant. Il est physiquement divisé en modules
eux-mêmes divisés en zones dans lesquelles sont disposées les touches.
Dans la présente partie de l'ISO/CEI 9995, les modules du clavier sont identifiés et la forme générale ainsi
que la disposition relative des modules sont spécifiées. La présente partie de l’ISO/CEI 9995 couvre
également l'espacement des touches et les caractéristiques physiques, qui constituent les principes régissant
l'emplacement des caractères et des symboles sur les touches.
La présente partie de l’ISO/CEI 9995 définit en outre un système de numérotation des touches qui s'applique
à tous les types de claviers numériques, alphanumériques et composites des équipements informatiques.
Elle précise les principes régissant l'emplacement des caractères et des symboles sur les touches de tous les
types de claviers numériques, alphanumériques et composites des équipements informatiques. Bien que le
clavier défini par l'ISO/CEI 9995 puisse être utilisé pour différentes langues, les spécifications s'appliquent aux
langues latines écrites de gauche à droite, et de haut en bas.
La disposition primaire au sein de la zone alphanumérique est établie dans la plupart des pays par une norme
nationale ou par l'usage. L'ISO/CEI 9995-2 donne les lignes directrices d'affectation et l'ISO/CEI 9995-3, les
dispositions complémentaires.
La présente partie de l’ISO/CEI 9995 définit les caractéristiques associées à l'interface 1 de la Figure 1.
L'ISO/CEI 9995 spécifie l'affectation des fonctions (caractères graphiques, fonctions de commande ou les
deux) aux touches. On a attribué des noms courants qui devraient être familiers pour les utilisateurs de clavier
ont été attribués aux caractères et fonctions. Les claviers ne génèrent généralement pas de fonctions de
commande codées, mais l'utilisation d'une touche de fonction de commande peut entraîner l'apparition de
fonctions codées durant l'échange de données, permettant ainsi d'obtenir le résultat escompté.
L'effet des touches qui affectent les états de clavier est précisé dans d'autres parties de l'ISO/CEI 9995.
