Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 213, Cable management
systems.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50520 on
2009-06-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2010-06-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-06-01
A cover plate or a cover tape which conforms to this European Standard is deemed to be safe for use.
This is a European Standard for cable management products used for electro-technical purposes. It relates
to the Council Directives on the approximation of laws, regulations and administrative provisions of the
Member States relating to Low Voltage Directive 2006/95/EC through consideration of the essential
requirements of this directive.
This European Standard is supported by separate standards to which references are made.

1 Scope
This European Standard establishes the requirements and tests for cover plates and cover tapes used for
the mechanical protection, identification and warning of the location of buried cables or buried conduits in
underground installations.
NOTE This European Standard does not apply to meshes and tapes falling under EN 12613.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
IEC 60417 (database), Graphical symbols for use on equipment
ISO 3864 (series), Graphical symbols - Safety colours and safety signs
3 Definitions
For the purpose of this document the following definitions apply.
3.1
cover plates
plates with a defined length and width that are linked one to another and are located above the sand ballast
that are intended
– to protect against mechanical damage the underground cables and/or conduit installations, and
– to identify in a prominent manner the location of the underground cables and/or conduit installations
along their length and width
3.2
cover tapes
tapes with a defined width that are located above the sand ballast that are intended
– to protect against mechanical damage the underground cables and/or conduit installations, and
– to identify in a prominent manner the location of the underground cables and/or conduit installations
along their length and width
4 General requirements
Cover plates and cover tapes shall be so designed and constructed that, when installed according to
manufacturer’s instructions, they provide mechanical protection and location warning of either a group of
cables or conduits in all their extension (length and width).
Compliance is checked by carrying out all the tests specified.

5 General conditions for tests
5.1 Test conditions
Tests according to this standard are type tests.
NOTE Annex A provides an overview of the tests to be applied on the cover plates and cover tapes.
Unless otherwise specified, the samples are tested as delivered and under normal conditions of use,
according to the manufacturer’s instructions.
Unless otherwise specified, the tests are carried out in the order of the clauses, at an ambient temperature
between 15 °C and 35 °C.
In case of doubt, the tests are made at an ambient temperature of (20 ± 5) °C.
5.2 Samples
Unless otherwise specified, each test is made on three new samples.
NOTE Certain tests, for instance the checking of dimensions, do not affect a change in the property of the samples; therefore these
samples are considered as new samples and can be used for further tests.
5.3 Validation of the results
The samples are submitted to all the relevant tests and the requirements are satisfied if all the tests are met.
If one sample does not satisfy a test due to an assembly or a manufacturing fault, that test and any
preceding one which may have influenced
