This ECMA Standard specifies requirements for Visual Display Units (VDU) using a non-CRT technology and an associated keyboard input.
This Standard applies specifically to VDUs used intensively in an office by a seated operator for data entry work, data acquisition, interactive communication, or word processing.
The requirements of this Standard are restricted to those physical features of the display unit and keyboard which are entirely under the control of the manufacturer and, as such, are mandatory.
This Standard does not address those ergonomic considerations which are under the control of the user since these can be given only as recommendations. Recommendations for these considerations applicable to office environment are to be found in ECMA TR/22.
