The TCO for the ergonomic quality from computer screens becomes from the roof federation of the Swedish employee and official trade union, to who cent ral organization assign. There are also TCO for office furniture (TCO '98, TCO '02, TCO '04), which evaluates among other things the chemical evaporation of office furniture and seating positions (Vorbeugung of back damage).

Although the strict TCO is not a legal requirement, they are very common. Even good inexpensive screens do not fulfill a TCO standard - however always to the current. Control takes place in a random sampling way.

TCO 92

TCO 92 is an extension of the MPR II standard (radiation measurement in the distance from 30 cm), the guarantee of switching the monitor off in Ruhepausen.

TCO 95

TCO 95 is a test seal of the cent ral organization for PCs, monitors and keyboards.

The Strahlenemission is examined according to TCO 92, the electronic characteristics according to DIN EN ISO 9241 and/or with monitors the brightness, contrast, picture stability and the character representation. The moreover one also the environmental compatibility is considered after TCO 92.

TCO 99

The test seal TCO 99 applies likewise to PCs, monitors and keyboards. It contained not only the limit values of the TCO 95 for electrical and magnetic fields, but defines for the first time also ergonomic guidelines. Furthermore the TCO-99-Spezifikation applies also to flat screens, keyboards and the complete arithmetic and logic unit. Screens are examined for the following criteria:

• Even brilliance
• Improved brilliance contrast
• Flare and Flackerfreiheit
• Ionizing radiation must go against 0
• Reflections of the screen housing
• Decreased noise of screens (unpleasant whistling)
• Prescribed capacity of the monitor in the condition by mode and in the switched off mode (max. 15W/max. 5W).

Besides the ecological guidelines were extended, it may be used no FCKWs or chlorinated solvents; blocked parts may not be bromhaltig and/or use chlorinated flame protection means. For the disposal of the devices the manufacturer must lock a contract with a recycling company.

TCO 03

, Additionally the monitor must have requirements such as TCO 99 a bright housing, since this is considered as eye-friendlier. The monitor should be also In order to make a relaxed head attitude possible, the view line should be lowered around approximately 35 "° from the horizontal one and be formed an approximately right angle with the picture screen surface. This requires that the screen in the height is adjustable and that the angle of the plan view can be changed. In addition it is important that the view from all sides exhibits a high quality on the screen. However everyone does not adhere to it. On the monitor "Samtron 78e 17" CRT Black" prangt a TCO03 sticker, although he has a black housing. The requirement that the monitor framework may not be to bright darkly or, was finally given up in October 2005.
