This standard specifies three types of barbed wire, conventional (C), reverse twist (RT) and barbed wire entanglement (BWE). Drawings of typical conventional and reverse twist barb
21、ed wire are given for information in annex A, Figures A.1 and A.2. 1 Scope This European Standard specifies zinc coated and zinc alloy coated steel barbed wire, conventional and reverse twist consisting of two stranded line wires, around which the barbs are tightly wound, a twist being imparted betw
22、een the barbs to restrict their movement. The barbed wire entanglement has a single line wire, around which the barbs are wound. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

26、following information shall be supplied by the purchaser at the time of enquiry and order: a) the number of this European Standard; b) quantity; c) type of barbed wire; d) coating type; e) barb spacing; f) length on reels; g) in the case of barbed wire entanglement (BWE), the type of finish; h) whet
27、her uniformity of coating is to be measured; i) inspection documentation requirements; j) agreed quality characteristics for testing (see clause 6). 4 Manufacture 4.1 Base metal The base metal of the barbed wire shall be of a good commercial quality steel wire, having the properties specified in Tab
28、le 1. 4.2 Fabrication 4.2.1 General The wire shall be zinc coated or zinc alloy coated to prEN 10244-2, before fabrication into barbed wire, except for barbed wire entanglement, which may be made from bright wire and suitably finish coated (other than zinc) as the final product. 4.2.2 Conventional b
29、arbed wire (C) 4.2.2.1 The conventional barbed wire shall be formed from two line wires complying with 4.1 and Table 1, twisted together with an approximate lay of 50 mm. Typical barb spacing is 75 mm7 mm, or 100 mm10 mm (or other spacing by agreement). Barb spacing shall be measured in accordance w
30、ith 8.4. 4.2.2.2 The barbs shall be tightly wrapped round the two stranded line wires by a method that prevents slipping, to expose the four barbs at an angle of approximately 908 apart in a plane at right angles to the axis of the line wire (e.g. see Figure 1). The barbs shall project a distance of
31、 12,5 mm3,5 mm from the centreline of the wire and the barb ends shall be cut at an angle not greater than 358 to the axis of the barb.

33、e (RT) 4.2.3.1 The barbed wire shall be formed from two line wires complying with 4.1 and Table 1, twisted together alternately with an approximate lay of 25 mm, typical barb spacing is 75 mm7 mm, or 100 mm10 mm (or other spacing by agreement). Barb spacing shall be measured in accordance with 8.4.
34、4.2.3.2 The barbs shall be formed by tightly wrapping round the two stranded line wires to expose the four barbs in a fixed position at an angle of approximately 908 apart in a plane at right angles to the axis of the line wires. The barbs shall project a distance of 12,5 mm3,5 mm from the centrelin
35、e of the wire and the barb ends shall be cut at an angle not greater than 358 to the axis of the barb. 4.2.3.3 The barbed wire shall not start to unwind until 75 % of the total nominal breaking load is applied. The unwinding of the barbed wire occurs when the stranded wires no longer extend under th
36、e influence of the applied load. The wires start to unravel in such a way that the number of twists of the wire around each other diminishes. This is noticeable in the stress-strain curve of the tensile test, where the first major drop in stress occurs. The tensile test shall be performed on a sampl
37、e of two barb spacings. 4.2.4 Barbed wire entanglement (BWE) 4.2.4.1 The entanglement shall be formed from wire complying with 4.1 and Table 1. The single line wire shall be crimped to an approximate pitch of 16 mm and approximate amplitude of 1 mm excluding the wire diameter. 4.2.4.2 The barbed wir
38、e shall be formed from one crimped line wire with four point barbs spaced at intervals between centres of 60 mm15 mm. The barbs shall be formed by wrapping round the line wire approximately four turns to expose the barbs in a fixed position at an angle of approximately 908 apart in a plane at right
39、angles to the axis of the line. The barbs shall project a distance of 15 mm to 20 mm from the centreline of the wire and the barb ends shall be cut at an angle not greater than 358 to the axis of the barb. 4.2.4.3 The barbed wire entanglement shall be supplied as a uniform cylindrical coil complying
40、 with a) or b) as follows: a) 68 turns approximately 1 m in diameter, with adjacent turns clipped together in a diamond pattern, the coil being capable of being extended to a length of 15 m; b) 32 turns 0,50 m0,1 m in diameter, clipped together in a diamond pattern, the coil being capable of being e
41、xtended to a length of 6 m. 4.2.4.4 Along the length of the coil adjacent turns in the coil shall be fastened together with five rows of clips made from austenitic stainless steel in the softened condition or galvanized steel. The rows of clips shall be spaced around the circumference of the coils a
42、t 728108 intervals. The start and end of the coil shall also be fitted with two additional clips 50 mm apart to secure the ends of the coil. The clips shall be completely closed round the two wires, but allowing sufficient movement to permit the formation of the concertina when the coil is extended,
43、 without the line wire being permanently deformed at the clips. NOTEIf the entanglement is manufactured from bright wire a finish should be applied, such as bitumen (by spraying or by dipping) to make it weatherproof. 4.3 Welding Joining of individual wires by means of an electric butt weld is permi
44、tted provided such joints are 10 m apart and are made in a workmanlike manner. The weld area shall be suitably protected against corrosion. 5 Requirements Before fabricating into barbed wire, the zinc or zinc alloy coated wire shall be tested in accordance with prEN 10244-2, class A for coating mass
45、, adherence and, where specified, the uniformity of the coating. Where samples are taken from the fabricated barbed wire, then the specified minimum coating mass shall be reduced by 5 % and, if specified, the minimum number of dips by one half minute. The nominal diameters, minimum tensile strengths
46、 and breaking loads of barbed wire shall be as in Table 1. Tolerances on dimensions shall comply with EN 10218-2 T1 for galvanized wire and EN 10218-2 T3 for bright wire.

47、y the application of statistical methods of sampling and analysis of results or, alternatively, by sampling and testing for the agreed quality characteristics at a rate of one reel in fifty. 7 Inspection and documentation Non-specific testing and inspection documentation shall be provided according
48、to EN 10021 and EN 10204. 8 Methods of test 8.1 Mechanical Mechanical tests shall be carried out in accordance with EN 10218-1. 8.2 Dimensions Dimensions shall be measured in accordance with EN 10218-2. 8.3 Zinc and zinc alloy coatings Zinc and zinc alloy coatings shall be assessed in accordance wit
49、h prEN 10244-1 and prEN 10244-2. 8.4 Barb spacing Barb spacing shall be measured and averaged over a 10 m sample. 9 Packaging 9.1 Conventional and reverse twist barbed wire shall be supplied on reels in typical minimum lengths of 100 m, 200 m, 250 m or 500 m. NOTEOther lengths may be supplied by agreement. 9.2 BWE shall be supplied in coils in bundles of fifteen.
