Описание (английский):

Within the general scope described in ISO/IEC 9995-1, this part of ISO/IEC 9995 specifies the alphanumeric section of a keyboard and the division of that section into zones; the arrangement, number, and location of the keys in the alphanumeric zone ZA0 of the alphanumeric section; and the layout and allocation of several control functions to the keys in the function zones of the alphanumeric section.

Overview

ISO/IEC 9995-2:2009/Amd 1:2012 is an amendment to Part 2 of the ISO/IEC 9995 series - the international standard for keyboard layouts for text and office systems. This amendment specifically defines requirements for numeric keypad emulation on alphanumeric keyboard sections. It was prepared by ISO/IEC JTC 1/SC 35 (User interfaces) and clarifies how an emulated numeric keypad should be allocated and represented on keyboards that do not have a dedicated numeric pad.

Key Topics and Technical Requirements

Emulation types required: If both a "Function" key and numeric emulation are provided, the emulated numeric keypad must support both the 1-2-3 layout and the 7-8-9 layout.

Reference positions for digit 5:

For the 1-2-3 type, digit 5 is at position D02.
For the 7-8-9 type, digit 5 is at position D08.

Allocation mapping (as specified in the amendment):

1-2-3 type: E01=1, E02=2, E03=3, E04=division, D01=4, D02=5, D03=6, D04=multiplication, C01=7, C02=8, C03=9, C04=subtraction, B01=0, B03=decimal separator, B04=addition.
7-8-9 type: E07=7, E08=8, E09=9, E10=division, D07=4, D08=5, D09=6, D10=multiplication, C07=1, C08=2, C09=3, C10=subtraction, B07=0, B09=decimal separator, B10=addition.

Labeling and symbols:

Symbols for emulated numeric keypad layouts need not be shown on the keyboard.
When shown, symbols for minus, divide and multiply may follow national or customary computer usage rather than the international glyphs in the document (examples include use of “/”, “*”, or local signs).

Practical Applications and Users

This amendment is useful for:

Keyboard manufacturers designing compact or laptop keyboards that rely on an emulation mode instead of a physical numeric keypad.

Firmware and device driver developers implementing correct key mappings for number-pad emulation.

Operating system and input-method developers ensuring consistent behavior and predictable numeric entry across locales.

Localization and UX designers deciding which symbols to show on keycaps based on national conventions.

Accessibility and ergonomic specialists who need predictable numeric input mappings for assistive technologies.

Keywords: keyboard layout standard, numeric keypad emulation, ISO/IEC 9995-2 amendment, alphanumeric keyboard, 1-2-3 layout, 7-8-9 layout, key allocation, keypad mapping.
