reasonable for the user.
Labelled products must meet strict environmental demands, for example in respect of the reduction of
electric and magnetic fields, along with physical and visual ergonomics and good usability.

Environmental Requirements
Brominated flame retardants are present in printed circuit boards, cables, wires, casings and housings. In
turn, they delay the spread of fire. Up to thirty percent of the plastic in a computer casing can consist of
flame retardant substances. These are related to another group of environmental toxins, PCBs, which are
suspected to give rise to similar harm, including reproductive damage in fish eating birds and mammals,
due to the bioaccumulative processes. Flame retardants have been found in human blood and
researchers fear that disturbances in foetus development may occur.
z
TCO'95 demand requires that plastic components weighing more than 25 grams must not contain
organically bound chlorine and bromine.
Lead
Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages the nervous
system and in higher doses, causes lead poisoning.
z
TCO'95 requirement Permits the inclusion of lead since no replacement has yet been developed.
Cadmium
Cadmium is present in rechargeable batteries and in the colour generating layers of certain computer
displays. Cadmium damages the nervous system and is toxic in high doses.
z
TCO'95 requirement states that batteries may not contain more than 25 ppm (parts per million) of
cadmium. The colour-generating layers of display screens must not contain any cadmium.
Mercury
Mercury is sometimes found in batteries, relays and switches. Mercury damages the nervous system and
is toxic in high doses.
z
TCO'95 requirement states that batteries may not contain more than 25 ppm (parts per million) of
mercury. It also demands that no mercury is present in any of the electrical or electronics components
concerned with the display unit.
CFCs (freons)
CFCs (freons) are sometimes used for washing printed circuit boards and in the manufacturing of
expanded foam for packaging. CFCs break down ozone and thereby damage the ozone layer in the
stratosphere, causing increased reception on Earth of ultraviolet light with consequent increased risks of
skin cancer (malignant melanoma).
z
The relevant TCO'95 requirement: Neither CFCs nor HCFCs may be used during the manufacturing of
the product or its packaging.
TCO'99-Ecological requirements for personal computers (TCO applied model only)
Congratulations!
You have just purchased a TCO'99 approved and labelled product! Your choice has provided you with a
product developed for professional use. Your purchase has also contributed to reducing the burden on the
environment and also to the further development of environmentally adapted electronics products.
This product meets the requirements for the TCO'99 scheme which provides for an international
environmental and quality labelling labelling of personal computers. The labelling scheme was developed
as a joint effort by the TCO(The Swedish Confederation of Professional Employees), Svenska
Naturskyddsforeningen(The Swedish Society for Nature Conservation), Statens Energimyndighet(The
Swedish National Energy Administration) and SEMKO AB.
The requirements cover a wide range of issuse: environment, ergonomics, usability, reduction of electric
and magnetic fields, energy consumption and electrical safety.
