DIN EN 12613:2009-09 EN 12613:2009 (E) 4 Introduction Visual warning devices are used for the manual or mechanized laying of cabl
24、es 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.
25、The warning devices are expected to last at least the lifetime of the equipments with which they are associated. DIN EN 12613:2009-09 EN 12613:2009 (E) 5 1 Scope This European Standard specifies the material, mechanical and functional (fitness for purpose) requirements for warning devices with visua
26、l characteristics manufactured from plastics, intended to indicate the presence of cables and piping systems buried in ground when opening trenches and more generally during digging work. This European Standard also specifies the test methods referred to in this document. This European Standard is a
27、pplicable to two types of visual warning devices: tapes (type 1) and meshes (type 2). 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
28、the referenced document (including any amendments) applies.

30、purposes of this document, the following terms and definitions apply. 3.1 type 1 warning device strip manufactured from plastics to warn of the presence of underground cables or pipes during excavation 3.2 type 2 warning device mesh/net manufactured from plastics to warn of the presence of undergrou
31、nd cables or pipes during excavation 3.3 nominal width of a warning device (W0) overall width of the warning device, as declared by the manufacturer, in millimetres 3.4 longitudinal direction direction corresponding to the extrusion direction, parallel to the length of the reel 3.5 transversal direc
32、tion direction parallel to the width (at right angle to the length) DIN EN 12613:2009-09 EN 12613:2009 (E) 6 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 the manufacture of warning
33、devices conforming to the requirements of this standard. The use of own or external reprocessable materials or recyclable materials shall be permitted for the manufacture of warning devices conforming to the requirements of this standard. The material, additives, colour masterbatches and inks for pr
34、inting, if added, shall have no detrimental effect on the environment. 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 ex
35、hibit 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.
36、5.3 Dimensional characteristics The nominal width, W0, of the warning device shall be as agreed between the manufacturer and the purchaser. For 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 straigh
37、t 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. For type 2 warning devices, the dimensional characteristics shall conform to Table 1 and it is recommended that the minimum reel length is equal or greater than
38、100 m or as agreed between the manufacturer and the purchaser.

40、nce with 6.3, the type 1 warning device shall withstand a load of 200 N during 5 min in the longitudinal direction, without starting of the separation of the weak points, if any, and shall not exhibit a reduction of more than 20 % of its width after removal of the load. When tested in accordance wit
41、h 6.3, the type 2 warning device shall withstand a load of 300 N during 5 min in longitudinal direction, without starting of the separation of the weak points, if any, and shall not exhibit a reduction of more than 20 % of its width after removal of the load. 5.4.3 Transversal rigidity When tested i
42、n accordance with 6.4, the deflection of outsides edges of the warning device shall be less or equal to W0 /4. If the nominal width of the warning device is greater than 500 mm, this requirement shall not apply. 5.4.4 Flatness When tested in accordance with 6.5, the warning device shall not exhibit
43、at any point a separation with respect to the reference surface greater than W0 /4. 5.5 Visual warning characteristics The visual characteristics of the warning devices are assessed by means of a test which simulates the opening of a trench with the bucket of an excavator. See A.1. When tested in ac
44、cordance with Annex A, the warning device shall exhibit at least one single part of a minimum length of 200 mm outside of the movable plate (which simulates the bucket) and at least one single part of a minimum length of 200 mm in the frame (which simulate the trench).
