Optical fibre cables - Part 5-10: Family specification for outdoor microduct optical fibre cables, microducts and protected microducts for installation by blowing
EN-IEC 60794-5-10 is a family specification that covers outdoor microduct optical fibre cables for installation by blowing and the associated microducts, which together make up a microduct optical fibre cable system. Although primarily designed for use with outdoor microduct applications, the cable products specified herein may be used individually for short lengths in other applications as agreed upon between supplier and customer. These may include short runs inside a building or in other outdoor applications, such as a transition between separate (unconnected) microduct systems, or from a microduct system to some other protective structure such as a cable conduit or tray. Systems built with components covered by this standard are subject to the requirements of IEC 60794-5 where applicable. Annex A shows examples of microduct optical fibre cables and microducts. Annex B describes a blank detail specification for outdoor microduct optical fibre cables and the associated microducts, and incorporates some minimum requirements. Detail product specifications may be prepared on the basis of this family specification using Annex B as a guide. Annex C provides normative requirements for microduct optical fibre cables. 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 and microducts tested shall be representative of the microduct optical fibre cable design and should be agreed between customer and supplier.

Câbles à fibres optiques - Partie 5–10: Spécification de famille - Câbles extérieurs à fibres optiques en micro-conduit, micro-conduits et micro-conduits protégés pour installation par soufflage
IEC 60794-5-10:2014 est une spécification de famille qui couvre les câbles extérieurs à fibres optiques en micro-conduit destinés à être installés par soufflage, et les micro-conduits associés, constituant ensemble un système de câbles à fibres optiques en micro-conduit. Bien qu'ils soient principalement conçus pour être utilisés avec des applications pour micro-conduit extérieur, les produits câbles ici spécifiés peuvent être utilisés individuellement sur de courtes longueurs dans d'autres applications, après accord entre le fournisseur et le client. Ceux-ci peuvent inclure de courtes longueurs à l'intérieur d'un bâtiment ou dans d'autres applications à l'extérieur, telles qu'une transition entre des systèmes de micro-conduits séparés (non connectés), ou un système de micro-conduit vers une autre structure protectrice telle qu'un conduit ou un chemin de câble. Les systèmes intégrant des éléments couverts par la présente norme sont soumis aux exigences de l'IEC 60794-5, le cas échéant. Mots clés: câbles extérieurs à fibres optiques en micro-conduit, installés par soufflage
Optični kabli - 5-10. del: Skupinska specifikacija za mikrokanale optičnih kablov za uporabo na prostem, mikrokanale in zaščitene mikrokanale za vgradnjo z vpihovanjem (IEC 60794-5-10:2014)
Standard EN-IEC 60794-5-10 je skupinska specifikacija, ki zajema mikrokanale optičnih kablov za uporabo na prostem, za gradnjo z vpihovanjem in sorodne mikrokanale, ki skupaj sestavljajo sistem optičnih kablov za uporabo na prostem. Čeprav so tukaj navedeni kabelski izdelki načrtovani predvsem za uporabo z mikrokanali za zunanjo uporabo, se lahko uporabljajo posamezno za krajše razdalje za druge namene, kot je dogovorjeno med dobaviteljem in stranko. To lahko zajema kratke razdalje v zgradbah ali pri zunanji uporabi, npr. pri prehodu med ločenim (nepovezanim) sistemom mikrokanalov, ali od sistema mikrokanalov do nekaterih zaščitnih struktur, kot so kabelske zaščitne cevi ali police. Za sisteme, zgrajene s komponentami, ki so zajeti v tem standardu, veljajo zahteve standarda IEC 60794-5, kjer je to primerno. Dodatek A zajema primere optičnih kablov za uporabo na prostem in mikrokanalov. Dodatek B opisuje okvirno podrobno specifikacijo za mikrokanale optičnih kablov za uporabo na prostem in povezane mikrokanale ter podaja nekatere minimalne zahteve. Podrobna specifikacija izdelka se lahko pripravi na osnovi te skupinske specifikacije z uporabo dodatka B kot vodnika. Dodatek C ponuja normativne zahteve za mikrokanale optičnih kablov. Na parametre, navedene v tem standardu, lahko vpliva merilna negotovost, ki se pojavi zaradi merilnih napak ali napak umerjanja zaradi pomanjkanja ustreznih standardov. Kriterije sprejemljivosti bi morali obravnavati ob upoštevanju teh pomislekov. Število preskušenih vlaken in mikrokanalov mora biti reprezentativno za načrtovanje mikrokanalov optičnih kablov in bi moralo biti dogovorjeno med stranko in dobaviteljem.

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60794-5-10 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical committee 86: Fibre optics. The text of this standard is based on the following documents: CDV Report on voting 86A/1496/CDV 86A/1542/RVC
