This standard specifies three types of barbed wire, conventional (C), reverse twist (RT) and barbed wire entanglement (BWE). Drawings of typi
20、cal conventional and reverse twist barbed wire are given for information in Annex A, Figures A.1 and A.2. BS EN 10223-1:2012EN 10223-1:2012 (E) 5 1 Scope This European Standard specifies zinc coated and zinc alloy coated steel barbed wire, conventional and reverse twist consisting of two stranded li
21、ne wires, around which the barbs are tightly wound, a twist being imparted between the barbs to restrict their movement. The barbed wire entanglement has a single line wire, around which the barbs are wound. 2 Normative references The following documents, in whole or in part, are normatively referen

28、cture 4.1 Base metal The base metal of the barbed wire shall be of a good commercial quality steel wire, selected from EN ISO 16120-1 and EN ISO 16120-2 and in a condition suitable for manufacture into barbed wire and base wire having the properties specified in the following Table 1. 4.2 Fabricatio
29、n 4.2.1 General The wire shall be zinc coated or zinc alloy coated to EN 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 barbed wire (C) 4.2.2.1
30、 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 mm 7 mm, or 100 mm 10 mm (or other spacing by agreement). Barb spacing shall be measured in accordance with 8.4. 4.2.2.2 The
31、 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 90 apart in a plane at right angles to the axis of the line wire (see Figure 1). The barbs shall project a distance of 12,5 mm 3,5 mm from the c
32、entreline of the wire and the barb ends shall be cut at an angle not greater than 35 to the axis of the barb. 4.2.3 Reverse twist type (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, typic
33、al barb spacing is 75 mm 7 mm, or 100 mm 10 mm (or other spacing by agreement). Barb spacing shall be measured in accordance with 8.4. 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 90
34、apart in a plane at right angles to the axis of the line wires. The barbs shall project a distance of 12,5 mm 3,5 mm from the centreline of the wire and the barb ends shall be cut at an angle not greater than 35 to the axis of the barb. 4.2.3.3 The barbed wire shall not start to unwind until 75 % of
35、 the total nominal breaking load is applied. The unwinding of the barbed wire occurs when the stranded wires no longer extend under the 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 th
36、e stress-strain curve of the tensile test, where the first major drop in stress occurs. The tensile test shall be performed on a sample of two barb spacing. 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 sh
37、all be crimped to an approximate pitch of 16 mm and approximate amplitude of 1 mm excluding the wire diameter. BS EN 10223-1:2012EN 10223-1:2012 (E) 7 4.2.4.2 The barbed wire shall be formed from one crimped line wire with four point barbs spaced at intervals between centres of 60 mm 15 mm. The barb
38、s 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 90 apart in a plane at right 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 ba
39、rb ends shall be cut at an angle not greater than 35 to the axis of the barb. 4.2.4.3 The barbed wire entanglement shall be supplied as a uniform cylindrical coil complying with (a) or (b) as follows: a) 68 turns 1 m 0,15 m in diameter, with adjacent turns clipped together in a diamond pattern, the
40、coil being capable of being extended to a length of 15 m; b) 32 turns 0,50 m 0,1 m diameter, clipped together in a diamond pattern, the coil being capable of being extended 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
41、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 at 72 10 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
42、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, without the line wire being permanently deformed at the clips. If the entanglement is manufactured from bright wire a finish should be
43、 applied, such as bitumastic (by spraying or by dipping) to provide durability during weather. 4.3 Welding Joining of individual wires by means of an electric butt weld is permitted provided such joints are 10 m apart and are made in a workmanlike manner. The weld area shall be suitably protected ag
44、ainst corrosion. 5 Requirements Before fabricating into barbed wire, the zinc or zinc alloy coated wire shall be tested for coating mass in accordance with EN 10244-2:2009 complying with class A for Zn coatings and class B for Zn95/Al5 alloys (for similar service life), adherence and where specified
45、, 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 and breaking loads of barbed wire
46、shall be as in Table 1. Tolerances on dimensions shall comply with EN 10218-2:2012, T1, for galvanized wire and EN 10218-2:2012, T3, for bright wire.
