ISO/IEC 9995-7:2009

Overview

ISO/IEC 9995-7:2009 - part of the ISO/IEC 9995 keyboard series - defines standard symbols used to represent keyboard functions on numeric, alphanumeric and composite keyboards. The standard provides a universal, non‑language dependent set of symbols (with English and French names/descriptions) so that keytops and user interfaces are predictable and consistent across products and markets. Symbols must be reproduced in the orientation shown in the standard and are intended to work with Latin‑alphabet, left‑to‑right writing systems.

Key topics and requirements

• Symbol set and table: A normative Table 1 lists function symbols (e.g., level locks, Caps Lock, Numeric Lock) with associated ISO 7000 reference numbers where applicable. Annexes include alphabetic and visual indexes and symbols for numeric sections.
• Function naming options: When indicating a function on a keytop, manufacturers may use the corresponding symbol, the function name or abbreviation, or an equivalent name in another language.
• Conformance: Equipment conforms to this part of ISO/IEC 9995 if it meets the requirements of Clause 5 (e.g., use and orientation of symbols).
• Multistandard alignment: Many symbols are also encoded in the universal character set (ISO/IEC 10646), and some symbols correspond to ISO 7000 graphically.
• Scope constraints: Specifications are written for Latin‑alphabet, top‑to‑bottom line progression and left‑to‑right character path; descriptions in the standard are informative and not normative.

Practical applications and users

• Keyboard and hardware manufacturers - for consistent keytop labelling across international products.
• Operating system and firmware developers - for mapping functions to physical keys and presenting standard symbols in UI documentation.
• Industrial and product designers - to create intuitive, language‑neutral control panels and portable device keyboards.
• Accessibility and localization teams - to ensure recognisable symbols for users across languages and regions.
• Standards bodies and certification labs - for conformity testing and ensuring compliance with keyboard layout norms.

Related standards

• ISO/IEC 9995 series (Parts 1, 2, 3, 4, 5, 8) - framework for keyboard layout areas and module definitions.
• ISO 7000 - graphical symbols for equipment (cross‑references used in ISO/IEC 9995‑7).
• ISO/IEC 10646 - universal character set (many keyboard symbols are encoded here).
