Regulatory Information
Both TCO '95 and TCO '99 also demand that mercury is not present
in any of the electrical or electronics components associated with the
labeled 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.
CFCs (freons):
The relevant TCO '95 and TCO '99 requirement states that neither
CFCs nor HCFCs may be used during the manufacture and assembly
of the product. CFCs (freons) are sometimes used for washing printed
circuit boards. CFCs 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 TCO '99 requirement permits
the inclusion of lead since no replacement has yet been developed.
* Bio-accumulative is defined as substances which accumulate within living organisms.
** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
