BS 6701:2004
and EN 50174-1:2009 require the production of an installation specification
that includes a technical specification.
EN 50174-1:2009 recommends that the installation specification
also contains an information technology strategy. EN 50174-1:2009
requires that the technical specification details the physical lifetime
for the installed cabling infrastructure.
The FIA feel that it is incumbent on the installer, although not
required by the published referenced standards, to advise the customer
if the components and techniques in the technical specification
would endanger these stated objectives. Failure to do so risks changes
being made to the installation specification during the installation
process which may incur delays, if not costs, for the installer
and frustration for the owner of the premises. |

Failure to plan the infrastructure to address expansion not only

The
risk element explained |

Legislation
and local/national regulations may apply requirements that go far
beyond the requirements specified in the installation specification.
Late advice of legislation and local/national regulations may have
an impact in terms of cost over-runs and potential delays. Furthermore,
failure to recognise and apply these local/national regulations
may result in legal penalty outside the terms of the installation
contract.
According to the published referenced standards, the installation
specification is required to draw the installers attention to the
applicable legislation and local/national regulations (but not required
to outline their provisions or requirements). Many installation
specifications fail to do so and it is recommended that any tender
response should ascertain whether any list of applicable legislation
and local/national regulations is exhaustive. |

NOTES:
BS 6701:2010 will reverse the order of its current clauses 4
and 5 to match the contents of the clauses of BS EN 50174-1:2009
and BS EN 50174-2:2009.
BS EN 50174-3:2011 will be restructured to match the format of BS
EN 50174-1:2009 and BS EN 50174-2:2009.
BS 6701:2010, clause 4.1.1, is expected to state that it is the
responsibility of the owner of the premises to ensure that “all
telecommunications cabling and telecommunications equipment shall
meet all the requirements of the BS EN 50174 series of standards."
BS 6701:2010, clause 4.1.2, is expected to state that the documentation
requirements of clause 4 of BS EN 50174-1:2009 and amendments
to it as published in due course shall be applied to telecommunications
equipment.
BS 6701:2004, clause 5.2.2, is expected to contain specific requirements,
that are the responsibility of the installer, for the implementation
of functional earths using either the protective earthing system
(clause 5.2.2.2) or separate functional earth cabling (clause
5.2.2.3). In addition, clause 5.2.2.4 is expected to contain specific
requirements for the earthing of cabinets, frames and racks (and
their conductive parts).
BS EN 50174-3:2011 will maintain references to EN 50174-2 for
cabling inside buildings while amending its requirements for cabling
outside buildings.
BS EN 50310:2010 is subject to substantial revision to allow
its normative application in all circumstances from the EN 50174-1
and EN 50174-2 standards.

The
risk element explained |
|
BS
EN 50174-2:2009 re-defines the segregation requirements between
balanced/co-axial cabling and mains power cabling in relation to
EMI. It is pleasing to note that future work within the electrical
installation standards will also reference the same base material
or state more demanding requirements.
It is not uncommon for their requirements to be ignored in the
installation specification or rendered impossible by the construction
of the building or the pre-provisioning of cable management systems.
It is therefore critical for the installer to highlight any non-compliances
to ensure that the risk of future complaint is reduced.

What the published standards say: |
|
BS 6701:2004,
clause 4.4.4.1, states the responsibility of the installer to meet
segregation requirements by explicit external reference to the BS
EN 50174 series and also contains specific requirements for the
"crossing" of mains power and information technology/telecommunications
cables.
BS 6701:2004, clauses 4.1.1 and 5.1.1, state that "all telecommunications
cabling shall meet all the requirements of the BS EN 50174 series
of standards."
BS EN 50174-1:2009, clause 4.2.1, states that “pathways,
cables, cabinets, frames, racks, closures and termination points
shall be located to minimize the effect of electromagnetic disturbances
and meet the mains power/information technology cabling segregation
requirements as defined by reference to EN 50174 2 and EN 50174
3.”
BS EN 50174-3:2003, clause 4.8, states requirements for the installation
of:
“metallic
information technology cabling and mains power cabling that share
the same cable
management”
by reference to clause 6.5 of BS EN 50174-2:2001;
aerial
cables, underground cables, power distributions systems and electrified
traction lines, and
hot zones
together with a wide variety of other situations including building
entrance facilities
by reference
to clause 5.9 (of EN 50174-3)."
NOTE:
where the requirements of safety and electrical interference demand
different limits for either spacing or physical separation, the
more stringent requirement shall take precedence.

BS EN 50174-1:2009 Amendment 1 (2010) and BS EN 50174-2:2009
Amendment 1 (2010) are expected to redefine “mains power”
cabling as “power supply” cabling - with a definition
that excludes PoE applications of information technology cabling.
BS EN 50174-3:2011 will amend the references to EN 50174-1 and
-2 standards by removing the dated references and the specific
clauses references.
