Conduit systems buried underground for the protection and management of insulated electrical cables or communication cables - Part 2: Polyethylene (PE), Polypropylene (PP) or Unplasticized poly(vinyl chloride) (PVC-U) conduit systems - Requirements for solid wall conduits, fittings and the system used in special applications
|Publication Date:||1 June 2020|
|ICS Code (Conduits for electrical purposes):||29.120.10|
This document specifies requirements and tests for PE, PP and PVC-U leak-tight solid wall conduit systems with circular cross section, manufactured individually or as part of an assembly having a specified performance time and buried underground to a maximum depth of 6 m for the protection and management of insulated conductors and/or power cables or communication cables.
Applications that require leak-tight solid wall conduit systems are:
- installation of cables in conduits by blowing;
- installation of cables in conduits by floating;
- trenchless installation of conduits.
This document is applicable to conduits with or without integral socket and fittings.
NOTE 1 Conduits in which cables are installed by blowing or floating can also be installed by conventional methods.
NOTE 2 Installation of cables can also be done by pulling and pushing.
NOTE 3 Within a thermoplastic conduit system, fittings made of other materials can be used but they are not specified in this document.
NOTE 4 It is the responsibility of the purchaser or specifier to take into account any relevant national regulations and installation practices or codes when selecting the products to be installed, based on the characteristics specified in this document.
NOTE 5 Microducts are covered by the relevant part of the EN 60794 series.
