Glossary 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 (see table). Electromagnetic radiation standards EMI (Electrical Magnetic Interference) The electrical and/or magnetic radiation coming from the working electrical or electronic equipment. EMS (Electrical Magnetic Sustainment) The ability of electrical or electronic equipment to function properly in the environment with electrical and/or magnetic interference. RETURN TO TOP OF THE PAGE F Flicker Very rapid variations in picture intensity caused by the finite time required for the electron beam to scan a picture onto the screen. Two kinds of flicker occur: line flicker caused by the electron beam scanning-in each line of the picture; and frame flicker (or field flicker if the picture is interlaced) caused by the frame repetition rate of 50 frames/second. Frame flicker is noticeable with GUI and DTP software (which have a light background), and can be very disturbing, especially for those who work regularly with displays - contributing to eye strain, headaches, visual blurring, stress, etc. The file:///D|/EDFU/crt_17_6/edoc/english/GLOSSARY/GLOSSARY.HTM (7 of 22)2005-04-08 ¤W¤È 11:21:39
