Overview

ISO/IEC 9995-2:2026 provides internationally recognized specifications for the alphanumeric section of keyboard layouts used in information technology, text, and office systems. Developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), this standard outlines the division of the keyboard’s alphanumeric section into zones, details the arrangement, number, and location of keys in the alphanumeric zone (ZA0), and specifies how various control functions are allocated and implemented in function zones. The standard enhances consistency and interoperability across keyboard designs and national layouts.

Key Topics

Division into Zones: The alphanumeric section is divided into the primary alphanumeric zone (ZA0) and two function zones (ZA1 and ZA2). The exact arrangement ensures compatibility with ISO/IEC 9995-1 standards.

Key Arrangement: Specifies both general and harmonized 48–50 graphic key keyboard arrangements, allowing for flexibility that meets national and linguistic requirements. The layout supports at least 48 graphic keys, including the space bar.

Graphic Character Allocation: Details requirements for core Latin alphabet characters, digits, and graphic symbols according to ISO/IEC 646, and provides guidance for the allocation of special graphic characters such as space, no-break space, and soft hyphen.

Control Functions: Defines how essential functions-such as Shift (Level 2 select), AltGr (Level 3 select), Lock, Tabulation, Return, Backspace, and Control-are assigned to non-graphic keys, including minimum presence and recommended placement within the keyboard layout.

Group Selection: Outlines mechanisms for group selection to support multilingual and multi-script input, with recommendations for group and single-select functions and visual indication of group status.

Numeric Keypad Emulation: Describes how keyboards can emulate a numeric keypad within the alphanumeric section, supporting both the “1-2-3” and “7-8-9” types for ease of data entry.

Keytop Markings: Recommends consistent key marking in line with ISO/IEC 9995-7, ensuring clear identification of functions.

Applications

Keyboard Manufacturing: Ensures that keyboard manufacturers can produce devices conforming to internationally recognized layouts, supporting both global and local requirements.

Software Development: Provides guidance for developers to implement consistent keyboard input handling, especially for multilingual and multi-script environments.

National and Industry Standards: Serves as a reference document for creating or updating national standards relating to keyboard layouts.

Accessibility and Usability: Standardized key placement and function allocation improve the user experience, promote ergonomic practices, and support accessibility initiatives.

Multilingual Systems: Facilitates the design of layouts catering to diverse languages and scripts by defining group selection and extra character input methods.
