Ecological requirements
Flame retardants
Flame retardants may be present in printed wiring board laminates, cables, and housings. Their
purpose is to prevent, or at least to delay the spread of fire. Up to 30% by weight of the plastic in a
computer casing can consist of flame retardant substances. Many flame retardants contain bromine or
chlorine, and these flame retardants are chemically related to PCBs (polychlorinated biphenyls).
Both the flame retardants containing bromine or chlorine and the PCBs are suspected of giving rise
to health effects, including reproductive damage in fish-eating birds and mammals, due to the
bio-accumulative* processes when not disposed of in accordance with strict standards for disposal.
TCO’99 requires that plastic components weighing more than 25 grams shall not contain flame
retardants with organically bound bromine or chlorine. Flame retardants are allowed in the printed
wiring board laminates due to the lack of commercially available alternatives.
Cadmium**
Cadmium is present in rechargeable batteries and in the colour-generating layers of certain computer
displays. TCO’99 requires that batteries, the colour-generating layers of display screens, and the
electrical or electronics components shall not contain any cadmium.
Mercury**
Mercury is sometimes found in batteries, relays and switches. TCO’99 requires that batteries shall
not contain any mercury. It also demands that mercury is not present in any of the electrical or
electronics components associated with the labelled unit. There is however one exception. Mercury is,
for the time being, permitted in the back light system of flat panel monitors as there today is no
commercially available alternative. TCO aims on removing this exception when a mercury free
alternative is available.
Lead**
Lead can be found in picture tubes, display screens, solders and capacitors. TCO’99 permits the use
of lead due to the lack of commercially available alternatives, but in future requirements TCO
Development aims at restricting the use of lead.
