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.
