Overview

SIST EN 50117-9-1:2026 is a European standard that specifies requirements for coaxial indoor drop cables designed for analogue and digital signal transmission within the frequency range of 5 MHz to 1 000 MHz. Developed by the Slovenian Institute for Standardization (SIST), this standard is part of the EN 50117 series and targets cables used in cable television, sound distribution, and interactive service networks. These cables are essential for reliable signal transmission in CATV, MATV, SMATV, and Broadband Communication Technology (BCT) systems, supporting both one-way and two-way communications.

The standard outlines the applicable test methods and essential requirements concerning the electrical, mechanical, environmental, and fire performance characteristics of indoor drop coaxial cables. It supports compliance with European directives, such as the Low Voltage Directive (2014/35/EU), by ensuring cable safety and performance in relevant applications.

Key Topics

• Scope of Application

  • Covers coaxial indoor drop cables operating at 5 MHz to 1 000 MHz
  • Used for both analogue and digital transmission in home and commercial environments
  • Supports CATV, MATV, SMATV, and BCT signals

• Cable Construction and Design

  • Specifies requirements for inner and outer conductors, dielectric materials (such as polyolefins), and PVC or halogen-free flame retardant sheaths
  • Insists on reliable sheath marking and labeling for traceability, including attenuation values, screening class, Euro-class, and supplier name

• Performance and Safety

  • Defines electrical performance parameters (attenuation, characteristic impedance, return loss, screening)
  • Specifies mechanical robustness (crush, bend, flexure tests)
  • Addresses environmental endurance (temperature cycles, cold performance)
  • Requires fire performance testing according to relevant EN standards

• Testing and Quality Assurance

  • Mandates compliance with test methods from the EN 50117 and EN 50289 series
  • Describes procedures for electrical, mechanical, and environmental tests to ensure ongoing cable integrity

• Regulatory Compliance

  • Ensures alignment with the Low Voltage Directive (2014/35/EU)
  • Describes material requirements under REACH and RoHS directives
  • Relates essential cable characteristics to Construction Products Regulation (CPR) for fixed installations

Applications

The cables specified by SIST EN 50117-9-1:2026 are widely used in:

• Television Signal Distribution
  • Connecting subscriber equipment within residential or commercial buildings to cable television provider networks
• Sound and Data Networks
  • Suitable for sound signal and broadband data transmission, supporting various interactive and digital services
• Interactive Home Services
  • Enable reliable and high-quality signal paths for smart devices and home automation where two-way communication is required
• Integrated Cable Systems
  • Used as indoor drop cables in complex RF and broadband communication systems, including full service television and multimedia setups

Typical users include cable network providers, property managers, system integrators, installers, and manufacturers of communication infrastructure.

4 Requirements for cable construction, design and installation
4.1 General
Cables according to this document are designed for an operating temperature range from −40 °C to
1)
+70 °C and at frequencies between 5 MHz and 1 000 MHz.
When designing the cable, consideration should be given to the maximum admissible current stated in the
detail specification. It is assumed that the raise of temperature of the inner conductor when submitted to the
maximum current under nominal ambient conditions does not affect the mechanical and electrical properties
of the cable.
Cables according to this document may be operated at voltages > 50 V AC or > 75 V DC according to the
detail specification of the manufacturer. However, these cables are not intended for direct connection to the
mains electricity supply or other low impedance sources.
Cables according to this document shall be designed and constructed according to EN 50290-2-1:2005,
Communication cables Part 2-1: Common design rules and construction and according to
EN 50290-4-1:2014, Communication cables - Part 4-1: General considerations for the use of cables -
Environmental conditions and safety aspects Compliance with the essential requirements of the LVD is
described in subclause 4.2.2 of EN 50290-4-1 .
The use of cables according to this document including delivery, storage and installation shall be in
accordance with EN 50290-4-2:2014, Communication cables - Part 4-2: General considerations for the use
of cables - Guide to use, unless otherwise specified.

1) This value is valid for applications without ampacity only, see also Table A.1 concerning max. DC current.
2) EN 50290-4-1:2014, 4.2.2 requires the use raw materials according to EN 50290-2-xx series, design
according to EN 50290-2-1 and dielectric tests according to EN 50289-1-3 and to EN 50290-2-1. Voltage
withstanding tests shall be performed between conductors and between the conductors or screen and the
outer surface of the sheath.
oSIST prEN 50117-9-1:2021

When designed and constructed in accordance with EN 50290-2-1:2005 and EN 50117-1:2019 and
submitted to spark testing, (see 5.1.2.5 in Table 1), CATV cables according to this document may be
installed together with Low Voltage cables.
Moreover, the tests according to Clause 5 of this document shall be performed after environmental and
ageing tests. In addition, the raw materials of these cables are defined in the EN 50290 series.
This ensures sufficient stability of the cables related to this characteristic for its life cycle.
Thus these cables are considered safe when:
— they are used for their intended purpose and applications;
— they are used under voltages and currents that do not exceed the limits given in the relevant detail
specification.
All cables covered by this document do not fall under the scope of the RED or the EMC Directive.
Nevertheless, transfer impedance and screening attenuation according to 5.1.3.6 and 5.1.3.7 in Table 2 shall
be specified in the relevant detail specification, if the intended application of the cable is the use in
combination with equipment under the RED or the EMC Directive, see also EN 50290-4-1:2014, 4.2.1.
4.2 Inner conductor
The conductor shall meet the requirements of EN 50117-1:2019, 4.2 and shall be solid and may be plain or
metal coated. Dimensions shall be in accordance with the detail specification.
There shall be no joint made subsequent to the last drawing operation.
In case of metal coated conductor, consideration shall be taken for the compatibility of the connector.
4.3 Dielectric
The dielectric material(s) shall be in accordance with EN 50117-1:2019, 4.3 and shall consist of polyolefin
materials, with EN 50290-2-37:2016 (polyethylene), EN 50290-2-38:2016 (polypropylene). Dimensions shall
be in accordance with the detail specification.
Unless otherwise specified, the nominal diameter over the dielectric should be one of the preferred values,
namely 3,7 mm, 4,8 mm and 7,2 mm.
4.4 Outer conductor or screen
The construction and material of the outer conductor (or screen) shall meet the requirements of
EN 50117-1:2019, 4.4 items b), f) or g). Where option b) is used, a double braid layer is required.
For braid constructions or helically wound wires, the braid angle shall be between 15° and 45°. The coverage
factor shall be greater than or equal to 65 %, or, when the cab
