Multicore and symmetrical pair/quad cables for digital communications - Part 4-1: Riser cables - Blank detail specification

IEC 61156-4-1:2009(E) relates to multicore and symmetrical pair/quad cables for digital communications in riser application. This blank detail specification determines the layout and style for detail specifications describing multicore and symmetrical pair(s)/quad(s) cables for digital communication in riser wiring. Detail specifications based on the blank detail specification may be prepared by a national standards organization, a manufacturer or a user. This edition constitutes a technical revision. The significant global technical change is the alignment with IEC 61156-4. This publication is to be read in conjunction with IEC 61156-1:2002 and IEC 61156-4:2009.

Overview

IEC 61156-4-1:2009 is the IEC blank detail specification template for multicore and symmetrical pair/quad cables intended for digital communications in riser applications. It defines the required layout, style and content structure for preparing detailed product specifications that describe riser-rated multicore and pair/quad cables. This edition (3.0, 2009) is a technical revision aligned with IEC 61156-4 and is intended to be read together with IEC 61156-1:2002 and IEC 61156-4:2009.

Key Topics

The standard provides a structured checklist and fields for all essential technical and administrative information. Key topics covered include:

• Cable identification and document metadata: prepared-by, document number, availability and related references.
• Cable description and construction: type and number of elements, nominal impedance, screening, application, category (e.g., category 3 or 5), conductor/insulation/sheath materials and construction details.
• Electrical characteristics: conductor resistance, resistance unbalance, dielectric strength and insulation resistance.
• Transmission characteristics: mutual capacitance, attenuation across frequencies (1 MHz to 100 MHz ranges listed), velocity/phase delay, characteristic impedance, return loss, near-end and far-end crosstalk (NEXT, FEXT).
• Mechanical characteristics: dimensional requirements, sheath thickness, minimum bending radius (static/dynamic), tensile and elongation properties, crush and impact tests.
• Environmental characteristics: temperature range (installation/operation), ageing tests, cold/heat shock, flame propagation and smoke/toxic gas emission tests for riser applications.
• Specification fields and notation: instructions for marking non-applicable items (NA) or not specified (NS), and references to sectional subclauses in IEC 61156-4:2009.

Applications

This blank detail specification is practical for:

• Preparing manufacturer product data sheets and factory test schedules.
• Writing procurement specifications for building cabling projects (riser spaces).
• Defining acceptance test criteria for quality control and type testing.
• Ensuring riser cable selections meet required transmission, mechanical and fire/smoke performance for vertical building runs.

Who uses this standard

• Cable manufacturers and designers
• National standards bodies and technical committees
• Spec writers, procurement teams and consultants for building cabling
• Test laboratories and compliance engineers
• System integrators and installers specifying riser cabling for digital communications

Related Standards

• IEC 61156-1:2002 - Generic specification for multicore and symmetrical pair/quad cables
• IEC 61156-4:2009 - Sectional specification: Riser cables
• ISO/IEC 11801 - Generic cabling for customer premises

Use IEC 61156-4-1:2009 as the authoritative template when drafting detailed riser cable specifications to ensure consistent, comprehensive and testable product documentation.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61156-4-1 has been prepared by subcommittee 46C: Wires and
