EN 50346 : Testing of Installed Cabling
Within premises, the importance of the information technology
cabling infrastructure is similar to that of other fundamental
building utilities such as heating,
lighting and mains power supplies. As with other utilities,
interruptions to service can have serious impact. Poor quality
of service due to lack of planning, use of inappropriate components,
incorrect installation, poor administration or inadequate support
can threaten an organization's effectiveness.
A series of European standards have been prepared to support
the successful installation of information technology cabling.
These are:
for design - EN 50173 and relevant application standards;
for specification, implementation and operation - EN 50174
-1, EN 50174-2 and EN 50174-3.
This European standard specifies the requirements for the
testing of installed balanced copper and optical fiber cabling.
Such testing is commonly undertaken at contract interfaces
and the requirements of this standard take the form of defined
test procedures ensuring that results obtained are relevant,
repeatable and credible. These test procedures may be:
referenced within the installation specification;
used during the implementation phase of the installation;
used during the operational phase to diagnose application
failures at the cabling level.
This standard does not define which tests should be applied
or the quantity or percentage of installed cabling to be
tested. The test parameters to be measured and the sampling
levels to be applied for a particular installation should
be defined in the installation specification and quality
plans for that installation prepared in accordance with
EN 50174-1.
