TCO’95

MultiSync LCD1920NX Black Model

Congratulations! You have just purchased a TCO’95

approved and labeled 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 the manufacturing. Since it has not been possible for

the majority of electronics equipment to be recycled in a

satisfactory way, 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 conventional electricity generation have a

negative effect on the environment (acidic and climate-influencing

emissions, radioactive waste, etc.), it is vital to conserve energy.

Electronics equipment in offices consume an enormous amount

of energy since they are often left running continuously.

What does labelling involve?

This product meets the requirements for the TCO’95 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), Naturskyddsforeningen (The Swedish

Society for Nature Conservation) and NUTEK (The National Board

for Industrial and Technical Development in Sweden).

The requirements cover a wide range of issues: environment,

ergonomics, usability, emission of 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 other

things. The product must be prepared for recycling and the

manufacturer is obliged to have an environmental plan 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.

TCO’95 is a co-operative project between TCO (The Swedish

Confederation of Professional Employees),

Naturskyddsforeningen (The Swedish Society for Nature

Conservation) and NUTEK (The National Board for Industrial and

Technical Development in Sweden).

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 fisheating 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

colourgenerating 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 colourgenerating

layers of display screens must not contain any cadmium.

Mercury**

Mercury is sometimes found in batteries, relays, switches, and

back-light systems, 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, except the back-light

system.

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.

**Lead, Cadmium and Mercury are heavy metals which are

Bio-accumulative.
