Information technology - Cabling installation - Part 3: Installation planning and practices outside buildings
This European Standard specifies requirements and provides recommendations for the following aspects of information technology cabling: a) planning; b) installation practice. This European Standard is applicable to all types of information technology cabling outside buildings including generic cabling systems designed in accordance with EN 50173 series. The requirements and recommendations of this European Standard may be applied to cabling that is defined as part of the building. The requirements and recommendations of Clauses 4, 5 and 6 of this European Standard are subject to any site-specific requirements and recommendations of Clause 7. The planning of the pathway systems, spaces and structures within the core and access network cabling as described in Figure 2 that are owned by access providers is excluded except for requirements and recommendations that provide basic safety, function and environmental objectives for mechanical, ingress and climatic characteristics (i.e. excluding pathway dimensions, distribution of spaces and similar constraints based on specific transmission methods). The installation practices applicable to all cabling installation methods are included by the provision of the necessary planning requirements and recommendations associated with each one with the exception of information technology cabling installed: – around or within aerial power supply or associated earth conductors; – on infrastructures carrying power supplies in excess of AC/DC 25 kV. This European Standard: 1) details the considerations for satisfactory installation and operation of information technology cabling; 2) excludes specific requirements applicable to other cabling systems (e.g. power supply cabling); however, it takes account of the effects other cabling systems may have on the installation of information technology cabling (and vice versa) and gives general advice; 3) excludes those aspects of installation associated with the transmission of signals in free space between transmitters, receivers or their associated antenna systems (e.g. wireless, radio, microwave or satellite). This European Standard is applicable to certain hazardous environments. It does not exclude additional requirements which are applicable in particular circumstances, defined by e.g. electricity supply and electrified railways. The requirements within this European Standard do not cover any additional requirements for the information technology cables installed in hazardous or stressful environments e.g. electricity supply and electric railway locations (see Clause 7).

Overview
EN 50174-3:2013/A1:2017 is the CLC European standard for information technology cabling installation planning and practices outside buildings. It specifies requirements and recommendations for planning and installation of all types of IT cabling deployed outdoors (including generic cabling per the EN 50173 series). The amendment A1 (2017) adds definitions, planning-for-repair guidance, updates to earthing/closure requirements and normative references.
Key topics and technical requirements
- Scope and exclusions
- Applies to outdoor IT cabling and may be applied to cabling considered part of a building.
- Excludes pathway planning owned by access providers (except basic safety, ingress and climatic objectives) and installations around/within aerial power or infrastructures > AC/DC 25 kV.
- Wireless/free-space transmission (radio, microwave, satellite) is excluded.
- Planning and administration
- Emphasises installation planning, documentation and Level 3 administration (EN 50174-1).
- New clause on planning for repair: resilience, service loops, cable sectioning, temporary repairs and contingency documentation.
- Pathway systems and routes
- Pathway surfaces of existing piping must not be used for direct cable attachment.
- Pathways must respect cable minimum bend radius (during installation, static and dynamic operation) and use radius limiters or prefabricated corners.
- Closures and shared enclosures
- Where IT and power cabling share closures, barriers meeting IP20 and tool-secured separate access are required; IT cable entries should be separately removable.
- Earthing, bonding and PEC
- Guidance on parallel earthing conductors (PECs): PEC shall be connected to an earthing system at least at one point; IT cable screen must not be relied on where PECs must carry large currents (lightning/power-fault).
- Default practice where local rules are absent: earth conductive cable parts at one end and insulate at the other; document chosen procedure.
- Fire and building entrance
- Cables of EuroClass F (EN 13501-6) or non‑compliant types should terminate outside the external fire barrier or within 2 m of penetration, or be contained in fire-rated trunking/conduit.
- Normative cross-references
- References updated to standards such as EN 50173, EN 50174-1/2, EN 50310, EN 62368-1/3, EN 13501-6, and relevant fibre/cable test standards.
Practical applications and users
Who uses EN 50174-3:
- Network designers and infrastructure planners for outdoor and access-network cabling
- Cabling installers, system integrators and contractors
- Telecom operators, access providers and municipalities planning ducts, chambers, aerial routes and street cabinets
- Facility managers and safety engineers responsible for bonding, earthing and fire compliance
Typical applications:

cable sheath or applying compressive loads exceeding that specified for the cable. These requirements
apply in three dimensions. This can be achieved by the use of pre-fabricated curved corners, drop-outs,
radius limiters or other means as shown in Figure 4.
