This standard specifies requirements for the German layout of keyboards for alphanumeric and/or numeric data and text input. Especially, layouts are standardized which incorporate all characters of all primary official languages of the world and all minority languages of Europe, as far as the Latin script is used for them. This standard applies to both the product keyboard and to software (e. g. keyboard drivers or operating systems). For ergonomic requirements regarding further aspects such as shape of keys, key centre spacing, key displacement, force to actuate the keys, geometric design of key legends or size of the strike surface, DIN EN ISO 9241 410 is applicable.
