SIST EN 50288-5-2:2013 is the Slovenian adoption of EN 50288-5-2:2013 from CENELEC. It specifies screened multi-element metallic cables for analogue and digital communication and control, especially work area cables and patch cord cables characterised from 1 MHz up to 250 MHz.

What does SIST EN 50288-5-2:2013 specify?

SIST EN 50288-5-2:2013 is a sectional specification for screened cables used in generic cabling systems. It covers work area cables from a telecommunications outlet to terminal equipment, and patch cord cables for patch panels and other distributors in building wiring systems.

The standard is written to be read together with EN 50288-1, which provides the generic provisions for this family of cables. Clause 1 also limits the intended electrical use to the voltages and currents normally found in communication systems, not low-impedance power sources such as public utility mains.

Annex	What it covers
Annex A	Maximum recommended voltage, current, current density and conductor temperature for POE applications
Annex B	Blank Detail Specification for screened work area, patch cord and data centre cables

What are the key requirements of SIST EN 50288-5-2:2013?

SIST EN 50288-5-2:2013 sets construction, transmission, mechanical, environmental and fire-related requirements, with the actual compliance checks listed in clauses 4 and 5. In practice, a supplier has to choose materials and build the cable so that the finished product passes the stated tests.

Cable construction

Clause 4 requires the conductor to be solid or stranded copper and the cabling element to be a pair or a quad. Screening may be applied to the element and to the cable core, and the sheath and insulation materials must be suitable to the relevant EN 50290 parts. This matters because the physical design determines whether the cable can meet the transmission and screening limits later in clause 5.

Clause 4 also states how elements are identified, laid up, filled and wrapped when those features are used. It explicitly says filling compound and moisture barriers are not applicable here, which narrows the constructions covered.

Electrical and transmission performance

Clause 5.1 covers the main electrical checks: low-frequency and d.c. measurements, then high-frequency and transmission behaviour. The tests include conductor resistance, dielectric strength, insulation resistance, capacitance balance, propagation delay, skew, attenuation, crosstalk, return loss, coupling attenuation, transfer impedance and mean characteristic impedance.

For users, this is the part that tells you whether the cable will support the communication performance expected in service. The tables also note practical points such as temperature correction for attenuation, extra attenuation for bundled cables, and the reclassification of ELFEXT to ACR-F and PSELFEXT to PSACR-F.

Mechanical, environmental and fire performance

Clause 5.2 checks how the cable survives handling and installation, including crush, impact, abrasion, tensile loading and simulated installation bends. Clause 5.3 covers cold bend, temperature cycling and hot shock. Clause 5.4 sends fire performance testing back to EN 50288-1.

Annex A adds POE guidance for voltage, current density and conductor temperature. Annex B gives a blank detail specification, which is useful when a purchaser and manufacturer need to write down the agreed cable description and performance values for a particular application.

What terms does SIST EN 50288-5-2:2013 define?

• screening of cable - a cable is screened when its core is covered by a continuous conductive layer that forms part of the shielding and grounding system.
• EX - means exogenous, or originating externally.
• POE - means Power Over Ethernet.
• ACR-F - the far-end attenuation-to-crosstalk ratio name used in the performance tables after the ELFEXT reclassification.
• PSACR-F - the power-sum version of ACR-F used for combined pair performance.

Who uses SIST EN 50288-5-2:2013?

SIST EN 50288-5-2:2013 is used by cable manufacturers, test laboratories, cabling designers, installers and quality teams working on communication cabling. It is also relevant to buyers and specifiers for office areas, patch panels and data centres where screened pair or quad cables are selected against defined electrical and mechanical performance.

What changed in SIST EN 50288-5-2:2013 from the previous edition?

SIST EN 50288-5-2:2013 supersedes EN 50288-5-2:2003. The foreword states three changes: a new Blank Detail Specification annex, minor corrections and updated references, and the reclassification of ELFEXT to ACR-F.

EN 50173 Series	Generic cabling systems framework for the intended applications
EN 50288-1	Essential provisions for applying this sectional specification
EN 50289 Series	Test methods for communication cables

EN 60811 Series	Test methods for non-metallic materials
IEC 60189-2	Colour coding for cable element identification

What does the SIST EN 50288-5-2:2013 document contain?

The document contains a short scope, normative references, terms and abbreviations, cable construction requirements, and a full set of tests and limits for completed cables. Clause 4 gives the construction rules for conductor, insulation, elements, screening and sheath, while clause 5 gives the electrical, mechanical, environmental and fire-performance test programme.

Annex A provides recommended POE operating limits for voltage, current and temperature. Annex B provides a blank detail specification with fields for cable description, materials, performance characteristics and agreed purchaser-manufacturer values, which is useful when turning the standard into a project or procurement specification.
