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.

Why do we have environmentally labelled computers?

In many countries, environmental labelling has become an established method for encouraging the adaptation

of goods and services to the environment. The main problem, as far as computers and other electronics

equipment are concerned, is that environmentally harmful substances are used both in the products and during

their manufacture. Since it is not so far possible to satisfactorily recycle the majority of electronics equipment,

most of these potentially damaging substances sooner or later enter nature.

There are also other characteristics of a computer, such as energy consumption levels, that are important

from the viewpoints of both the work (internal) and natural (external) environments. Since all methods of

electricity generation have a negative effect on the environment (e.g. acidic and climate-influencing emissions,

radioactive waste), it is vital to save energy. Electronics equipment in offices is often left running continuously

and thereby consumes a lot of energy.

What does labelling involve?

This product meets the requirements for the TCO’99 scheme which provides for international and environmental

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) and Statens Energimyndighet (The Swedish National Energy Administration).

Approval requirements cover a wide range of issues: environment, ergonomics, usability, emission of electric

and magnetic fields, energy consumption and electrical and fire safety.

The environmental demands impose restrictions on the presence and use of heavy metals, brominated and

chlorinated flame retardants, CFCs (freons) and chlorinated solvents, among other things. The product must

be prepared for recycling and the manufacturer is obliged to have an environmental policy which must be

adhered to in each country where the company implements its operational policy.

The energy requirements include a demand that the computer and/or display, after a certain period of

inactivity, shall reduce its power consumption to a lower level in one or more stages. The length of time to

reactivate the computer shall be reasonable for the user.

Labelled products must meet strict environmental demands, for example, in respect of the reduction of

electric and magnetic fields, physical and visual ergonomics and good usability.

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.

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.

* Bio-accumulative is defined as substances which accumulate within living organisms

** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.

Environmental Requirements

Brominated flame retardants

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 bio-accumulative* processes. Flame retardants have been found in human blood and researchers

fear that disturbances in foetus development may occur.

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.

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.

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.

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).

The relevant TCO’95 requirement: Neither CFCs nor HCFCs may be used during the manufacturing of

the product or its packaging.

* Bio-accumulative is defined as substances which accumulate within living organisms.
