European foreword

This document (EN 12613:2021) has been prepared by Technical Committee CEN/TC 249 “Plastics”,

the secretariat of which is held by NBN.

This European Standard shall be given the status of a national standard, either by publication of an

identical text or by endorsement, at the latest by July 2021, and conflicting national standards shall be

withdrawn at the latest by July 2021.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 12613:2009.
The major modifications compared to the previous edition are:
— Addition of a reference to Regulation (EC) No 1907/2006 (REACH) (Clause 4);

— Addition of the apparatus for measurement of dimensional characteristics (5.3.1);

— Review of the tolerances for nominal widths greater than 1 000 mm (5.3.3);

— Deletion of the transversal rigidity (5.4.3 in EN 12613:2009), since it is not a discriminating

characteristic for products with width ≤ 500 mm;

— Addition of a sentence to specify that the case of absence of rupture of the test specimen is

considered as successful (5.5);

— The method according EN 60898-1, for the resistance of printing, is now recommended only

(instead of being mandatory) and other methods are allowed (5.9);

— Review of the number of test pieces reduced from four to one. In addition, when the test is not

successful, an acceptance criteria is defined for retesting (6.1);

— Extension of the tolerances on the test temperature for the products submitted to testing (6.1);

— Deletion of 6.4 of EN 12613:2009 (transversal rigidity);

— Deletion of Clause 7 of EN 12613:2009 as factory production control tests do not necessarily

appear in a product standard;
— In A.2, deletion of the paragraph beginning with “IMPORTANT” (no added value);

— Review of Figure A.4 and expressing of minimum gaps between the plates and the transversal walls

of the central compartment;

— Addition of Table A.2 giving the characteristics of an alternative quality of EPDM sheets (A.2.4);

— Review of tolerances for EPDM sheets (Table A.3);
— Total load values were changed to minimum values (Table A.4);
— Review of the number of test pieces (A.3);
---------------------- Page: 5 ----------------------

Introduction

Visual warning devices are used for the manual or mechanized laying of cables and piping buried in

ground such as electrical power cables, communication cables, pressure and non-pressure piping

systems.

The purpose of warning devices is to warn of the presence of a pipe or a cable, when opening a trench,

to indicate its orientation and to identify the equipment protected.

The warning devices are expected to last at least the lifetime of the equipment with which they are

associated.

4 Material

The material shall be made of any thermoplastic material, e.g. polyethylene (PE) or polypropylene (PP),

to which are added those additives necessary for manufacturing warning devices conforming to the

requirements of this document.

The use of own or external reprocessed materials or recycled materials shall be permitted for

manufacturing warning devices conforming to the requirements of this document.

The material, additives, colour masterbatches and inks for printing, if added, shall have no detrimental

effect on the environment.

Environmental, health and safety aspects, as well as the use of regulated substances [1] are to be taken

into account for the design process of the products.
5 Requirements
5.1 Colour

The colour of the warning device shall be as agreed between the manufacturer and the purchaser.

5.2 Appearance and colour fastness

The appearance, colouring and marking of the warning device shall not exhibit any change when tested

in accordance with 6.2. No discoloration or change of the initial colour shall be permitted. Only a change

in surface appearance (e.g. gloss/matt) shall be permitted.

For a given type of warning device (design, width), the colour fastness shall be tested for each colour.

5.3 Dimensional characteristics
5.3.1 General

The nominal width, W , of the warning device shall be as agreed between the manufacturer and the

purchaser.

The dimensional characteristics of the warning device shall be measured by means of:

a) a measuring tape/metal ruler, capable of measuring to an accuracy of 1,0 mm for the width of the

warning device;

b) a metal ruler, capable of measuring to an accuracy of 0,5 mm for the internal perimeter of the

openings, if relevant;

c) a calliper gauge, capable of measuring to an accuracy of 0,1 mm, for measuring the minimum width

of the strands, if relevant.
5.3.2 Type 1 warning devices

Each individual value of the width shall be equal or greater than 50 mm and the outside edges of the

warning device shall be straight and parallel.

The deviation of each outside edge, towards outside or inside relatively to the mean line, shall be less or

equal to 2 mm.
5.3.3 Type 2 warning devices
The width of the Type 2 warning device shall conform to Table 1.

It is recommended that the minimum reel length is equal or greater than 100 m or as agreed between

the manufacturer and the purchaser.
5.4 Laying characteristics
5.4.1 General

For ease of use, the warning devices need sufficient flatness and longitudinal mechanical strength to

maintain their shape.
5.4.2 Tensile withstand strength

When tested in accordance with 6.3, the type 1 warning device shall withstand a load of 200 N during

1 min in longitudinal direction, without starting of the separation of the weak points, if any, and shall
