Overview

IEC 61196-6-4:2018 is an International Electrotechnical Commission standard that defines the detail specification for 75-7 type CATV drop coaxial cables. It applies to coaxial communication cables described in IEC 61196-6 and is intended to be used together with IEC 61196-1:2005 and IEC 61196-6:2009. The standard covers cable construction, dimensions, electrical and environmental tests, marking and performance requirements for operating frequencies from 5 MHz to 3 000 MHz and nominal impedance 75 Ω.

Key topics and technical requirements

• Cable types and construction
  • Variants: 75-7S (dual shield), 75-7T (tri-shield), 75-7Q (quad-shield); messenger variants available (e.g., 75-7T/M).
  • Core materials: inner conductor (BC = bare copper or CCS = copper-clad steel), foamed PE dielectric, multilayer shields (aluminium/polymeric tape, aluminium alloy wire, tinned copper), sheath materials (PVC, PE, LSZH).
  • Representative dimensions and tolerances are specified (e.g., inner conductor dia. ~1.63 mm, dielectric dia. ~7.11 mm, outer jacket dia. ~10.16–10.34 mm).
• Electrical and transmission parameters
  • Characteristic impedance: 75 Ω ± 3 Ω (measured at 200 MHz).
  • Operating frequency range: 5 MHz – 3 000 MHz.
  • Conductor resistance, insulation resistance (≥ 10 000 MΩ·km), and withstand/spark test voltages are specified.
  • Return loss and attenuation limits (detailed attenuation limits referenced in Annex B).
  • Regularity of impedance / pulse return-loss requirements and measurement procedures (IEC 61196-1-115).
• Shielding and EMC
  • Screening attenuation classes defined per shield type; numerical minimums (for example, dual/tri/quad shield classes with required dB ranges across specified bands).
  • Transfer impedance limits after flex tests (measured according to IEC 62153 and IEC 61196-1-314).
• Environmental and mechanical tests
  • Temperature ranges for different sheath types (PE: −40 °C to 70 °C; PVC and LSZH variants noted).
  • Mechanical tests: minimum bending radius 10 × D, flexure procedures, cold bend, climatic sequence, damp heat, UV stability and thermal ageing with limits on attenuation change (typically ≤ 7%) and physical integrity.
• Identification and marking
  • Cable identification, type naming and marking requirements are covered in Annex A.

Applications and users

IEC 61196-6-4 targets manufacturers, test laboratories, procurement/specification engineers, and installers in sectors such as:

• CATV distribution systems
• Satellite television receiving systems
• Surveillance and control systems
• Bidirectional Hybrid Fibre Coax (HFC) networks

Use this standard when specifying 75-7 CATV drop cables for performance, compliance testing, and procurement.

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.
