在ISO/IEC 9995-1中描述的一般范围内，ISO 9995-9:2016定义了键盘上一组图形字符的分配，当与现有国家版本键盘布局结合使用时，允许输入此处定义的最小字符库。 该曲目旨在解决使用拉丁语书写所有当代语言所需的所有字符，以及使用其他语言书写一些主要语言的标准拉丁音译。它还包含ISO 8859-1中包含的所有符号和标点符号，以及印刷和办公室使用中常用的其他一些符号和标点。 它还以同样的程度处理了一些其他文字（希腊语、西里尔语、亚美尼亚语、格鲁吉亚语、希伯来语）的字符（在西里尔语的情况下，省略了俄罗斯联邦的一些少数民族语言，这些语言只剩下几百人）。 它提供了在ISO 9995-9:2016的未来版本中包括其他脚本（例如阿拉伯语、天成文书）的方法（例如通过修订）。 此外，它还涉及国际音标（IPA）。 ISO 9995-9:2016主要用于文字处理和文本处理应用，可与全尺寸键盘以及移动设备（“智能手机”或手持计算机）上的微型键盘一起使用，尤其是只有26个基本拉丁字母的键，但没有数字专用键的键盘。

Within the general scope described in ISO/IEC 9995-1, ISO 9995-9:2016 defines the allocation on a keyboard of a set of graphic characters which, when used in combination with an existing national version keyboard layout, allows the input of a minimum character repertoire as defined herein. This repertoire is intended to address all characters needed to write all contemporary languages using the Latin script, together with standardized Latin transliterations of some major languages using other scripts. It also contains all symbols and punctuation marks contained in ISO 8859-1, together with some selected other ones commonly used in typography and office use. It also addresses characters of some other scripts (Greek, Cyrillic, Armenian, Georgian, Hebrew) to the same extent (in the case of Cyrillic, leaving out some minority languages of the Russian Federation which have only a few hundred speakers left). It provides means to include other scripts (e.g. Arabic, Devanagari) in future versions of ISO 9995-9:2016 (e.g. by amendments). Furthermore, it addresses the International Phonetic Alphabet (IPA). ISO 9995-9:2016 is primarily intended for word-processing and text-processing applications, to be used with full-sized keyboards as well as with miniature keyboards found on mobile devices ("smartphones" or handheld computers), especially ones which have only keys for the 26 basic Latin letters but no dedicated keys for digits.
