Ta evropski standard določa splošne zahteve in preskuse za podzemne kanalske sisteme za zaščito in upravljanje izoliranih vodnikov in/ali napajalnih ali komunikacijskih kablov.
Ta evropski standard se uporablja samo za vode s krožnim prečnim prerezom.
Zahteve, ki so opisane v tem standardu, veljajo za vse vodnike,
– ki so nameščeni posamično ali kot del sestava;
– če se kabel vgrajuje z vlečenjem ali potiskanjem.
Standard prEN 50626-2 določa posebne zahteve in preskuse, ki so potrebni za posebne načine uporabe.
OPOMBA: Primeri posebnih načinov uporabe zajemajo posebne tehnike vgradnje cevi, med alternativnimi tehnikami za namestitev kablov pa je vgradnja brez izkopa.

Introduction
CENELEC TC 213 is responsible for the development of the EN 50626 series, which consists of two separate
parts, both 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.
EN 50626-2 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.
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 conduit systems with circular cross section buried
underground for the protection and management of insulated conductors and/or power cables or communication
cables installed individually or installed as a part of an assembly where the cable is installed by pulling or
pushing.
This document does not include requirements for leak-tightness according to EN ISO 13259 and performance
time.
NOTE 1 EN 50626-2 specifies requirements and tests for performance time and leak-tightness for solid wall conduit
systems made of PE, PP and PVC-U buried underground where the cables are installed by blowing or floating or conduits
are installed by trenchless methods.
