Electromagnetic radiation standards

International standards set to limit electromagnetic emissions from monitors. There are currently

two important standards both derived from regulations originally laid down by Swedish

authorities.

MPR-II

The standard originally proposed by the Swedish National Board of Measurement and Testing. It

set maximum levels of electromagnetic radiation emitted by monitors, and has now been adopted

as a world standard. MPR-II defines maximum permitted electrostatic, magnetic and electric field

levels measured at a distance of 50 cm from the center of the monitor (see table).

TCO

In 1991, the Swedish Tjänstemannens Central Organization (TCO, Swedish confederation of

Professional Employees ) set a standard even more severe than MPR-II, especially for

alternating electric fields (AEF). The TCO standard is more severe since not only are the

permitted field levels reduced compared with MPR-II, but the measuring distance is also reduced
