This document is a family specification that covers sewer cables and conduits for installation by
blowing and/ or pulling in non-man accessible storm and sanitary sewers, also applicable for
man-accessible and lateral ones. Systems built with components covered by this standard are
subject to the requirements of sectional specifications EN 60794-3 and EN 60794-4 where
applicable.
Sewer cable and conduit constructions have to meet the different requirements of the sewer
operating companies and / or associations regarding chemical, environmental, operational,
cleaning and in general maintenance conditions.
A table of preferential applications, describing sewer cable characteristics versus methods of
installation is reported in Annex A for non-man accessible sewers.
Clause 4 describes a blank detail specification for sewer cables and conduits for installation by
blowing and/or pulling in storm and sanitary sewers. It incorporates some minimum
requirements.
Detail specifications may be prepared on the basis of this family specification.
The parameters specified in this standard may be affected by measurement uncertainty arising
either from measurement errors or calibration errors due to lack of suitable standards.
Acceptance criteria should be interpreted with respect to this consideration.
The number of fibres tested is representative of the sewer cable and should be agreed between
the customer and supplier.
