Procedures

The
risk element explained |

BS
6701:2004 and EN 50174-1:2009 require the production of a Quality
Plan that details the measures and procedures to be adopted to demonstrate
compliance with BS EN 50174-1, the referenced cabling design document
(e.g. EN 50173-2) and the installation specification.
A Quality Plan is essentially a register of the Method Statements
to be applied to the specific installation, tailored to reflect
the applicable contractual responsibilities and interfaces, together
with information detailing the competence of the personnel to undertake
the tasks outlined in the Method Statements.
Method Statements may comprise textual or photographic procedures
(the increased use of digital photography allowing complex procedures
e.g. cable dressing inside cabinets or closures, to be more easily
specified).
One of the benefits resulting from the production of Quality Plan
is that it forces the scrutiny of the Installation Specification
- without an Installation Specification, it is impossible to produce
a Quality Plan - other than in the most general terms. The production
of a Quality Plan by an installer and its agreement with the owner
of the premises is therefore a contractual milestone that requires
both parties to recognise that (a) the Installation Specification
is valid (b) a document called an "Quality Plan" has been
passed to the owner of the premises and (b) considered, by the owner
of the premises, as acceptable.
The failure to produce a Quality Plan suggests that there is no
common approach to the installation, testing or inspection tasks
to be applied.

BS
6701:2004, clause 4.1.2, states that it is the responsibility of
the installer to ensure that “a Quality Plan shall be provided
in accordance with BS EN 50174-1 for telecommunications equipment
and telecommunications cabling.”
BS EN 50174-1:2009, clause 4.1.4, requires that “The quality
plan is the responsibility of the installer and shall be agreed
before the installation commences.”
BS EN 50174-1:2009, clause 5.1.2.1, requires that “a Quality
Plan shall be prepared that specifies the procedures to demonstrate
compliance with:
 the
requirements and recommendations of this standard;
 the
requirements of the referenced cabling design document (e.g. EN
50173-2);
 the
installation specification.”
Where these procedures are contained within the installation specification,
BS EN 50174-1, clause 5.1.2.1, requires that ”the installer

BS 6701:2004
and EN 50174-1:2009 require the production of a Quality Plan that
details the procedures for the transfer of responsibilities during
the installation.
A Quality Plan is essentially a register of the Method Statements

the applicable contractual responsibilities and interfaces, together
with information detailing the competence of the personnel to undertake
the tasks outlined in the Method Statements.
The handover of responsibility at a particular stage in a contract
is obviously a critical milestone requiring an identified and agreed
procedure or series of procedures (be they document-, inspection-
or test-based). Method Statements are critical to ensure that the
process of handover is completed in a controlled, agreed and therefore
risk-averse manner.
NOTE: The installation-specific Method Statement may incorporate
a third-party document by simple external reference. |

BS 6701:2004
and EN 50174-1:2009 require the production of a Quality Plan that

A Quality Plan is essentially a register of the Method Statements

the applicable contractual responsibilities and interfaces, together
with information detailing the competence of the personnel to undertake
the tasks outlined in the Method Statements.
The risk of matching inadequately trained or incompetent personnel
to the specific tasks identified in the Quality Plan is self-evident.
The creation of a Quality Plan by selecting from a series of Method
Statements allows an installer to ensure that internal training
records can be applied to identify the personnel competent to undertake
the task identified in each Method Statement. These internal training
records can also, as appropriate, detail relevant training schemes
of national or industry origin.

and 5 to match the contents of the clauses of BS EN 50174-1:2009
and BS EN 50174-2:2009.
BS EN 50174-3:2010 will be restructured to match the format of BS
EN 50174-1:2009 and BS EN 50174-2:2009.
BS 6701:2010, clause 5.1.1, is expected to state that it is
the responsibility of the cabling installer 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 5.1.2, is expected to state that the documentation
requirements of clause 5 of BS EN 50174-1:2009 shall be applied

BS EN 50310:2010, is expected to provide requirements and recommendations
in this area and contain external references to EN 60950 (to become
EN 62368).

The
risk element explained |
|
BS 6701:2004
and EN 50174-1:2009 require the production of a Quality Plan that
details the procedures for the for the acceptance of cabling components
and the cabling installation.
The risk of incorrect component selection and/or inappropriate
installation techniques is self-evident in terms of resulting delays
and associated costs. The post-installation impact of incompatibility
of components with the appropriate fire requirements or chemical
environment may involve removal and re-installation of the components
involving significant associated costs.
The Quality Plan represents a useful vehicle to assessing any such
risks. |

BS
6701:2004, clauses 4.1.2, states that it is the responsibility of
the installer to ensure that "installation, operating and maintenance
instructions for all telecommunications equipment and telecommunications
cabling shall be obtained."
BS 6701:2004, clause 4.1.3.1, states that it is the responsibility
of the installer to identify, document and advise (to the owner
of the premises housing, and/or the operator of, the telecommunications
system), "the potential for damage to, and subsequent interruption
of service provided by, the telecommunications equipment and telecommunications
cabling to be installed following activation of the fire extinguishing
system."
BS 6701:2004, clause 4.1.2, states that it is the responsibility
of the installer to ensure that “a Quality Plan shall be provided
in accordance with BS EN 50174-1 for telecommunications equipment
and telecommunications cabling.”
BS EN 50174-1:2009, clause 4.1.4, requires that “The quality
plan is the responsibility of the installer and shall be agreed
before the installation commences.”
BS EN 50174-1:2009, clause 5.1.2.1, requires that “the Quality
Plan shall detail the procedures for the acceptance of cabling components
… .”
Where these procedures are contained within the installation specification,
BS EN 50174-1, clause 5.1.2.1, requires that ”the installer
shall confirm that those elements shall be complied with.”
BS EN 50174-3:2003, clause 4.1, requires that “all the installed
cable shall comply with the relevant product safety requirements.”
BS EN 50174-3:2003, clause 4.4, requires that “the choice
of cables shall be made according to the national regulation relating
to the Construction Products Directive."
NOTE: in the UK this has no direct impact since there are no
national regulations. A future BS 8492 may assist in this area.

BS 6701:2004

A Quality Plan is essentially a register of the Method Statements

with information detailing the competence of the personnel to undertake
the tasks outlined in the Method Statements.
Alongside the Method Statements, there should be an Equipment Schedule

The risk of applying incorrect or uncalibrated inspection and test

Furthermore, the labelling and logging of the test cords used (and
