BS EN 12613:2009EN 12613:2009 (E) 4 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

21、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 equipmen

22、ts with which they are associated. BS EN 12613:2009EN 12613:2009 (E) 5 1 Scope This European Standard specifies the material, mechanical and functional (fitness for purpose) requirements for warning devices with visual characteristics manufactured from plastics, intended to indicate the presence of

23、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 applicable to two types of visual warning devices: tapes (type 1) and meshes (type 2

The use of own or external repr

30、ocessable 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 printing, if added, shall have no detrimental effect on the environment. 5 Requirements 5.

31、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 i

32、nitial 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 The nominal width, W0, of the warning device shall be as

33、 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 straight and parallel. The deviation of each outside edge, towards outside or inside relatively

34、 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 100 m or as agreed between the manufacturer and the purchaser.

36、ics 5.4.1 General For ease of use, the warning devices need sufficient rigidity, 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 5 min in the l

37、ongitudinal 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 with 6.3, the type 2 warning device shall withstand a load of 300 N during 5 min in longitudinal

38、 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 in accordance with 6.4, the deflection of outsides edges of the warning device shall be less o

39、r 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 at any point a separation with respect to the reference surface greater than W0 /4. 5.5 Visua

40、l 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 accordance with Annex A, the warning device shall exhibit at least one single part of a minimum

41、 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).
