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
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, Both the flame
retardants containing bromine or chloride and the 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 demand requires that plastic components weighing more than 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
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 doses. The relevant requirement states that batteries may not contain any mercury.
It also demands that mercury is not present in any of the electrical or electronics components associated
with the unit.
(freons)
The relevant requirement states that neither nor may be used during the
manufacture and assembly product. (freons) are sometimes used for washing printed circuit
boards. break down ozone and thereby damage the ozone layer in the stratosphere, causing
increased reception on earth of ultraviolet light with e.g. increased risks of skin cancer (malignant
melanoma) as a consequence.
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. The relevant TC0’99 requirement permits the
inclusion of lead since no replacement has yet been developed.
l
defined substances which accumulate within living organisms
Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative
