TCO’9

Congratulations! You have just purchased a TCO’99 approved an

abelled product! Your choice has provided you with a product develope

or professional use. Your purchase has also contributed to reducing th burden on the environment and also to the further development o environmentally adapted electronics products

Why do we have environmentally labelled computers

In many countries, environmental labelling has become an established method for encourag ing the adaptation of goods and services to the environment. The main problem, as far a computers and other electronics equipment are concerned, is that environmentally harmfu substances are used both in the products and during the manufacturing. Since it has not bee possible for the majority of electronics equipment to be recycled in a satisfactory way, mos of these potentially damaging substances sooner or later enter Nature

There are also other characteristics of a computer, such as energy consumption levels, that ar important from the viewpoints of both the work (Internal) and natural (external) environments Since all methods of conventional electricity generation have a negative effect on th environment (acidic and climate-influencing emissions, radioactive waste, etc.), it is vital t conserve energy. Electronics equipment in offices consume an enormous amount of energ since they are often left running continuously

What does labelling involve

This product meets the requirements for the TCO’99 scheme which provides for international an environmental labelling of personal computers. The labelling scheme was developed as a join effort by the TCO (The Swedish Confederation of Professional Employees), Svensk Naturskyddsforeningen (The Swedish Society for Nature Conservation) and Statens Energimyndighe (The Swedish National Energy Administration)

The requirements cover a wide range of issues: environment, ergonomics, usability, emission o electrical and magnetic fields, energy consumption and electrical and fire safety

The environmental demands concern restrictions on the presence and use of heavy metals brominated and chlorinated flame retardants, CFCs (freons) and chlorinated solvents, among othe things. The product must be prepared for recycling and the manufacturer is obliged to have a environmental plan which must be adhered to in each country where the company implements it 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 o 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 reductio of electric and magnetic fields, physical and visual ergonomics and good usability

Environmental Requirement

Flame retardant

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 o

lame retardant substances. Most flame retardants contain bromine or chloride and these ar related to another group of environmental toxins, PCBs, which are suspected to give rise to sever health effects, including reproductive damage in fisheating birds and mammals, due to the bio

khol

accumulative* processes. Flame retardants have been found in human blood and researchers fea that disturbances in foetus development may occur

TCO’99 demand requires that plastic components weighing more than 25 grams must not contai

lame retardants with organically bound chlorine and bromine. Flame retardants are allowed i the printed circuit boards since no substitutes are available

–continue

Lead*

Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages th nervous system and in higher doses, causes lead poisoning

TCO’99 requirement permits the inclusion of lead since no replacement has yet been developed

Cadmium*

Cadmium is present in rechargeable batteries and in the color generating layers of certain compute

isplays. Cadmium damages the nervous system and is toxic in high doses

TCO’99 requirement states that batteries, the color generating layers of display screens and th electrical or electronics components must not contain any cadmium

ercury**

Mercury is sometimes found in batteries, relays and switches, Mercury damages the nervous syste and is toxic in high doses

TCO’99 requirement states that batteries may not contain any Mercury. It also demands that n mercury is present in any of the electrical or electronics components associated with the display unit

(freons)

CFCs (freons) are sometimes used for washing printed circuit boards. CFCs break down ozone an thereby damage the ozone layer in the stratosphere, causing increased reception on Earth o ultraviolet light with consequent increased risks of skin cancer (malignant melanoma)

The relevant TCO’99 requirement; Neither CFCs nor HCFCs may be used during the manufacturin and assembly of the product or its packaging

*Bio-accumulative is defined as substances which accumulate within living organisms **Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative
