Guidelines of the European Union
An essential goal of the European Union is the realization of a single European
market and thus free trade. This means that quantitative import limitations of
goods between the member states are prohibited.
Goods that endanger the safety of persons or the environment are an exemp-
tion. Member states can prohibit such products on their country's territory. To
ensure free trade for these products, the national safety regulations of the
member states are standardized via guidelines set forth by the European Un-
ion.
These guidelines apply for a number of product classes, such as for example
machines, medical products, as well as toys. However, corresponding guide-
lines were also developed for additional common safety aspects of products,
such as protection against electricity, explosion protection or electro-magnetic
compatibility. The guidelines are directed towards member states, who must
implement them into the respective national laws. The guidelines therefore
have legally binding effects.
With the CE label the manufacturer certifies to have met all obligations of the
EC guidelines applicable for the product. The CE symbol, which is affixed to
the products by the manufacturer himself, is the "passport" within the EU and
intended for the overseeing authorities.
In addition, independent, accredited certification organizations can verify the
conformity with the EU guidelines and confirm this with a EU design sample
certification.
Both the Electromagnetic Compatibility Directive (EMC 2004/108/EC) and the
Machinery Directive (MD 2006/42/EC) are applicable to the handheld termi-
nals.
Machinery Safety
Additional measures must be taken wherever faults arising in the machinery
may cause personal injury or significant material damage. These measures
must also guarantee a safe operating condition for the whole system in the
event of a fault. According to the Machinery Directive (MD) a machine is con-
sidered to be "a totality of components or appliances linked together, of which
at least one can move". The directive also implies, that " Machinery must be
designed and constructed so that it can be operated, adjusted and maintained
without putting persons at risk when these operations are carried out under the
conditions foreseen".
Although the handheld terminal is not, strictly speaking, a machine, it does,
however, perform important tasks to guarantee the safety functions of a ma-
chinery to which it is attached.
The handheld unit has, for example, the “Emergency Stop" safety function and
an enabling control device for use in special operating modes. It is, as a result,
a “Safety Component" in the sense of the Machinery Directive.
