Introduction
CENELEC TC 213 is responsible for the development of the EN 50626 series, which consists of two separate
parts, each covering different products/applications.
This document covers requirements and tests for conduit systems buried underground for the protection and
management of insulated conductors and/or power cables or communication cables having a specified
performance time and which are leak-tight solid wall conduit systems and manufactured in PE, PP and PVC-U.
EN 50626-1 covers requirements and tests for conduit systems buried underground for the protection and
management of insulated conductors and/or power cables or communication cables.
For on-site storage, CEN/TS 1046 can be used as a guidance.
A conduit system buried underground that conforms to this document is deemed to be safe for use.
This is a European Standard for cable management products used for electro-technical purposes. It relates to the
Council Directives on the approximation of laws, regulations and administrative provisions of the Member States
relating to Low Voltage Directive 2014/35/EU through consideration of the essential requirements of this Directive.
This document is supported by separate standards to which references are made.
1 Scope
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.
