EN 50290-4-1:2001:
− Clauses related to fire reaction and fire resistance have been updated to take into account the recent
development of supporting standards for the CPR.
This standard should be read in conjunction with EN 50290-1-1 and is completed by generic, sectional,
family and detail specifications, as appropriate, to describe in a detailed manner each type of cable with
its specific characteristics.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent
rights.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association.
This standard covers the Principle Elements of the Safety Objectives for Electrical Equipment Designed
for Use within Certain Voltage Limits (LVD - 2006/95/EC).
EN 50290-4, Communication cables — General considerations for the use of cables, is divided into the
following sub-parts:
− Part 4-1: Environmental conditions and safety aspects [the present document];
− Part 4-2: Guide to use.
1 Scope
This European Standard gives the environmental conditions and safety aspects of symmetrical, coaxial
and optical cables used for the infrastructure of communication and control networks.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 50290-1-2 apply.
4 Environmental conditions and installation aspects
4.1 General
The reliability of the cables and their expected lifetime depend upon how the environmental conditions
(during storage, installation and operation) are taken into account in their design.
1) By the time of publication of the present document, this reference is at Committee Draft stage in the IEC under the reference
"6A/1582/CDV".
- 5 - EN 50290-4-1:2014
The following subclauses address environmental aspects that can impact the reliability of the
communication cables.
4.2 Relationship with EC directives
4.2.1 EMC Directive
Though cables as products are not under the scope of the EMC directive, they are used to interconnect
apparatus as described in the directive.
The equipment supplier, system designer and operators shall be aware that the interconnection of cables
may affect the overall system EMC performance.
Mitigation practices as developed in some installation guides can decrease the level of electromagnetic
influence.
To help the systems users and the designers to fulfil the EMC directive requirements by an adequate
choice of cables, the electromagnetic behaviour of each cable shall be given in the relevant specification
and described by screening performance and balanced properties.
4.2.2 Low voltage directive
Depending upon the actual application for which they are used, communication and control cables may
have to carry signals, the voltage of which can exceed DC 100 V or AC 75 V.
These cables fall under the low voltage directive and have to be designed, tested and marked
accordingly.
The relevant cable specification shall take into account the requirements of the low voltage directive.
Demonstration of compliance with the essential requirements of the LVD is done either through a
technical file or when the cable fulfils the following diagram.
Figure 1
4.2.3 Construction product directive/ Construction Product regulation
4.2.3.1 General
Communication and control cables fall under the scope of the construction product regulation, when
installed in construction works.
In case where CPD applies consideration shall be taken to the following:
– resistance to fire where applicable (e.g. for fire alarm systems, fire fighting support systems,…);
– reaction to fire;
– durability;
– release of dangerous substances under normal circumstances.
4.2.3.2 Resistance to fire
Communication cables packaging and/or labelling shall be tested according to EN 50289-4-16 for the
claimed Euroclass as defined in EN 13501-3.
When applicable, the communication cables packaging and/or labelling will be CE marked according to
2)
, Annex ZZ.
EN 50XXX:201X
4.2.3.3 Reaction to fire
EN 50575 specifies reaction to fire performance requirements, test and assessment methods for
communication cables, which are intended for use in construction works.
After having been tested according to EN 50575 for the claimed Euroclass as defined in EN 13501-6,
communication cables packaging and/or labelling shall be CE marked according to EN 50575:2014,
Annex ZZ.
4.2.3.4 Durability
The relevant cable specification shall include mechanical and environmental requirements to be tested in
accordance with EN 50289-3 (all parts) and EN 50289-4 (all parts) (see 4.3).
Durability is presumed to be demonstrated when the cables pass the mechanical and environmental tests
as given in the sectional specification.
4.2.3.5 Release of dangerous substances
During the normal operating life of the cable no dangerous substances given in the updated list of the
Council Directive 76/769/EEC will be released.
Cables using materials according to the EN 50290-2-2X series comply with this requirement.
Other materials shall be subjected to the appropriate tests.
4.3 Environmental conditions
4.3.1 Relationship between environmental conditions and severities of testing
4.3.1.1 General
The purpose of environmental engineering is to render the product and the environment compatible. It
should take all economic and technical aspects into consideration and thereby choose the best test
methods and correct severities for the evaluation of the product's ability to comply with the environmental
conditions. A test program for the product is defined whereby the test sequence together with the test
methods and limits are specified.
4.3.1.2 Environmental conditions
The environmental conditions shall be evaluated by measurements or by other information available so
that statistically probable characteristic values can be established corresponding to the highest possible
2) At the date of publication of the present document, EN 50XXX:201X, which is currently bound to be entitled, Power, control and
communication cables — Cables for general applications in construction works subject to fire resistance requirements, is not
published yet.
