RoHS
European Union Directive 2002/95/EC restricting the
use of specific hazardous substances in electrical and
electronic equipment governs the use of hazardous
substances in equipment and components.
In the face of the massive spread of disposable
electronic goods, the object of the directive is to
prohibit the most troublesome constituent
substances from the products. These prohibitions
include the ban on toxic flame retardants in the
manufacture of cables. The directive also seeks to
increase the use of appropriate substitute products
and lead-free soldering.
The toxic substances currently used in electronics are
rated as highly hazardous to the environment. These
substances sometimes leak out of landfill into the
environment. They do not readily decompose easily
and can therefore enter nature's environmental
cycles. The RoHS regulations are designed to ban the
use of these substances in products. The substances
affected are
 Lead
 Mercury
 Cadmium
 Hexavalent chromium
 Polybrominated biphenyl (PBB)
 Polybrominated diphenylether (PBDE)
All Leica Geosystems cables meet this standard.
WEEE
The WEEE Directive (Waste Electrical and Electronic
Equipment) is the EU Directive 2002/96/EC for
reducing the growing quantity of electro-scrap arising
from discarded electrical and electronic equipment.
The objective is the avoidance, reduction and
environmentally compatible disposal of the rising
quantities of electronic scrap through extending the
responsibilities of the manufacturers.
The EU directive came into effect in January 2003.
The EU member states had until 13th August 2005 to
incorporate the directive into their national legislation
and put in place a national e-waste return system.
From December 2006, at least 4 kg electronic scrap
per person per year must be recycled. The Electrical
and Electronic Equipment Act (ElectroG) came into
force in Germany on 16th March 2005 and joined the
WEEE and RoHS directive (Restriction of Hazardous
Substances in electrical and electronic equipment) as
part of German law.
EMC
Compliance with regulations is controlled on the
international stage by standards and directives on
electromagnetic compatibility. National legislation
also demands that Leica systems can operate
perfectly in an interference-laden environment and
do not cause interference with other devices and
systems. Cables play an important role to play in this.
Within European Union member states, EU Directive
2004/108/EC on electromagnetic compatibility
defines the limits for transmitted electromagnetic
interference and resistance to it
Summary
Cables – data transfer cables in particular – are an
important accessory for achieving a proper set up of
an instrument. Anyone not working as a cable
specialist would never think that a cable has to fulfil
so many requirements and specifications before it
can be called a "Leica-approved cable".
But all these criteria have to be fulfilled in order to
provide a specific minimum standard and ensure the
best possible performance under the most
unfavorable conditions.
Usually a great deal of importance is attached to the
surveying instrument and the influence of each
accessory on the accuracy of the system is often
overlooked.
