This ECMA Standard specifies a keyboard layout for use with national versions of keyboard layouts so that the complete repertoire of ISO 6937/2 or sub-set of it can be input by the combined layout. It also specifies particularities of operation of some keys.
This Standard does not define physical characteristics of the keyboard such as the shape, size or colour of the keys, nor the style of the graphic symbols shown on the keys. Neither does this Standard define the coded representations of the graphic characters of the Common Secondary Set or of the Primary Set.
