Current information regarding TCO'95 approved and labelled products may also be obtained via the

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. There 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 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.1
*Bio-accumulative is defined as substances, which accumulate within living organisms
**Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
