    Abstract - (Show below) - (Hide below)

    This document is a family specification that covers drinking water pipe cables and sub-ducts for installation by blowing and/or pulling / dragging in drinking water pipes. 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. Drinking water pipe cable and sub-duct constructions have to meet the different requirements of the drinking water companies and/or associations regarding chemical, environmental, operational interactions and in general maintenance conditions. A table of preferential applications, describing drinking water pipe cable characteristics versus methods of installation is reported in Annex A for drinking water pipe cables. Clause 4 describes a blank detail specification for drinking water pipe cables and sub-ducts for installation by blowing and/or pulling / dragging in / flowing drinking water pipes. 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.
