Overview

EN 61196-3:1998 (IEC 61196-3) is the sectional specification for radio frequency coaxial cables for local area networks (LANs). It selects appropriate quality-assurance procedures, test and measurement methods from the generic IEC 61196-1 specification, and prescribes recommended ratings, construction guidance and general performance requirements specific to coaxial LAN cabling. Where this sectional specification and IEC 61196-1 conflict, EN 61196-3 takes precedence.

Key topics and technical requirements

• Scope and purpose: Defines performance limits, complementary test methods and minimum test severities for coaxial cables intended for LAN use.
• Installation limits:
  • Maximum pulling force: 20 N
  • Installation temperature: 0 °C to +60 °C
  • Working and storage temperature: −15 °C to +60 °C
  • Minimum bending radius: specified in the relevant detail specification
• Materials & construction:
  • Inner conductor: plain or tinned annealed copper complying with IEC 60028; strand jointing by cold pressure weld, brazing or silver solder where required
  • Dielectric, outer conductor/screen and sheath types are selected in the detail specification; outer conductor options include single braid, double braid or metallized film + braid
  • Sheath: plastic materials with options for flame retardant, low-smoke and halogen-free constructions
• Identification & delivery:
  • Sheath marking repeat frequency ≥ once per metre
  • Delivery on drums/coils; cable ends to be sealed to prevent moisture ingress
• Electrical & transmission characteristics (to be measured per IEC 61196-1):
  • Characteristic impedance, attenuation (including after ageing), loop DCR, outer conductor DCR, capacitance, velocity ratio, return loss
  • Screening effectiveness: surface transfer impedance and screening attenuation
  • Voltage rating: 30 V r.m.s.
• Mechanical & environmental tests:
  • Tensile strength, elongation, bending at low temperature, dielectric adhesion
  • Fire performance tests (e.g. IEC 60332-1) and considerations for smoke/toxicity/halogen emission

Applications and practical value

• Use EN 61196-3 when specifying, procuring, manufacturing or testing coaxial RF cables for local area networks in buildings and premises.
• Helps ensure consistent electrical performance (impedance, attenuation, screening) and reliable mechanical/installation characteristics.
• Valuable to: cable manufacturers, network designers, installers and contractors, test laboratories, procurement teams and EMC/installation engineers who need standardized test methods and construction guidance for LAN coaxial cabling.

Related standards

The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical reports or guides and they are accepted by the National Committees in that sense.4)In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights.
