3 Terms and definitions
For the purpose of this document, the following terms and definitions apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at http://www.electropedia.org/
3.1
cover plate

plate with a defined length and width that are linked one to another and are located underground, above the

cables and/or conduits that are intended:

— to protect against mechanical damage to 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 tape

tape with a defined width that are located underground, above the cables and/or conduits and that are

intended:

— to protect against mechanical damage to 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
3.3
hygroscopic material

material having the characteristic of enabling attraction or holding water greater than 1,0 % by weight of the

material from the surrounding environment at 23 °C and 50 % relative humidity

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 cables or conduits in

all their extension (length and width).
Compliance is checked by carrying out all the tests specified.

Products made of hygroscopic material shall fulfil requirements of 5.3 before testing.

Compliance is checked by inspection of raw material supplier’s data sheet.
5 General conditions for tests
5.1 Test conditions
Tests according to this document 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 Conditioning

Samples made of hygroscopic material shall be conditioned for at least 240 h, at a temperature of (23 ± 2)

°C and a relative humidity between 90 % and 95 %. All tests shall be carried out immediately after this

conditioning.
5.4 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 that could have influenced the results of the test shall be repeated, and also the tests that

follow shall be carried out in the required sequence on another full set of samples, all of which shall comply

with the requirements.

NOTE The applicant can submit, together with a number of samples specified in 5.2, the additional set of samples

that could be required, should one sample fail. The testing station will then, without further request, test the additional

samples and will only reject them if a further failure occurs. If the additional set of samples is not submitted at the same

time, the failure of one sample will entail rejection.

When toxic or hazardous processes are used, due regard shall be given to the safety of the persons within

the test area.

advertisement sign as specified on ISO 3864 (series), and the message ELECTRIC CABLES;

— for cover plates and cover tapes intended for protecting and indicating the presence of information

and communication
