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.

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
