ISO/IEC 9995

From Wikipedia, the free encyclopedia

ISO/IEC 9995 (less formally "ISO 9995") is an ISO standard defining layouts of computer keyboards. It defines a keyboard as having three groups of key assignments:

• Group 1 is the basic layer with a base and shift (lower and upper case)
• Group 2 is the national layer with a base and shift. There is a locking shift to access this.
• Group 3 allows for supplemental characters to be entered. This is a single plane and uses a non-locking shift.

Some keyboards in use are defined outside of this standard.

The ISO/IEC 9995 standard dates to 1994 and has undergone several updates over the years. It currently consists of the following parts:

• ISO 9995-1:2006 General Principles Governing Keyboard Layouts
• ISO 9995-2:2002 Alphanumeric Section
• ISO 9995-3:2002 Common Secondary Layout of the Alphanumeric Zone of the Alphanumeric Section
• ISO 9995-4:2002 Numeric Section
• ISO 9995-5:2006 Editing Section
• ISO 9995-6:2006 Function Section
• ISO 9995-7:2002 Symbols Used to Represent Functions
• ISO 9995-8:2006 Allocation of Letters to the Keys of a Numeric Keyboard

[edit] ISO 9995-3

ISO 9995-3 defines a common secondary layout for the alphanumeric keyboard.

[edit] ISO 9995-8

ISO 9995-8:2006 defines an assignment of the 26 letters a-z to the number keys of a numeric keypad.
