Application Area



This part of ISO 9241 provides guidance on basic properties of the working environment to support display screen work. The characteristics of the work environment are considered under six headings: natural and artificial lighting (including glare control); sound and noise (including the reduction of noise effects); mechanical vibrations (for example, from air conditioning systems or nearby industrial activities); electromagnetic fields and static electricity (and its effects on the image quality of visual displays); thermal environment (including thermal comfort and humidity); and space organisation and workplace layout. The standard includes four annexes that cover: lighting; methods for measuring and evaluating sound; measurement, evaluation and assessment of whole-body vibrations; and thermal environment (this includes recommended values for thermal comfort).
