Environmental requirements

Flame retardants

Flame retardants are present in printed circuit boards, cables, wires, casings and housings.

Their purpose is to prevent, or at least to delay the spread of fire. Up to 30% of the plastic in a

computer casing can consist of flame retardant substances. Most flame retardants contain

bromine or chloride, and those flame retardants are chemically related to another group of

environmental toxins, PCBs. Both the flame retardants containing bromine or chloride and the

PCBs are suspected of giving rise to severe health effects, including reproductive damage in

fish-eating birds and mammals, due to the bio-accumulative* processes. Flame retardants have

been found in human blood and researchers fear that disturbances in foetus development may

occur.

The relevant TCO'99 demand requires that plastic components weighing more than 25 grams

must not contain flame retardants with organically bound bromine or chlorine. Flame retardants

are allowed in the printed circuit boards since no substitutes are available.

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. The

relevant TCO'99 requirement states that batteries, the colour-generating layers of display

screens and the electrical or electronics components must not contain any cadmium.

Mercury**

Mercury is sometimes found in batteries, relays and switches. It damages the nervous system

and is toxic in high doses. The relevant TCO'99 requirement states that batteries may not

contain any mercury. It also demands that mercury is not present in any of the electrical or

electronics components associated with the labelled unit. There is however one exception.

Mercury is, for the time being, permitted in the back light system of flat panel monitors as today

there is no commercially available alternative. TCO aims on removing this exception when a

Mercury free alternative is available.

CFCs (freons)

The relevant TCO'99 requirement states that neither CFCs nor HCFCs may be used during the

manufacture and assembly of the product. CFCs (freons) are sometimes used for washing

printed circuit boards. CFCs break down ozone and thereby damage the ozone layer in the

stratosphere, causing increased reception on earth of ultraviolet light with e.g. increased risks

of skin cancer (malignant melanoma) as a consequence.

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. The relevant TCO'99 requirement

permits the inclusion of lead since no replacement has yet been developed.

TCO'03-Ecological requirements for personal computers (TCO'03 applied model only)

Congratulations!

The display you have just purchased carries the TCO'03 Displays label. This means that your

display is designed, manufactured and tested according to some of the strictest quality and

environmental requirements in the world. This makes for a high performance product, designed

with the user in focus that also minimizes the impact on our natural environment.

Some of the features of the TCO'03 Display requirements:

Ergonomics

Good visual ergonomics and image quality in order to improve the working environment for the

user and to reduce sight and strain problems. Important parameters are luminance, contrast,

resolution, reflectance, colour rendition and image stability.
