32、 Clause 7). 5 Manufacture 5.1 Base metal The base metal of the hexagonal netting shall be of good commercial quality steel selected from EN ISO 16120-1 and EN ISO 16120-2 and in a condition suitable for manufacture into netting. 5.2 Fabrication The netting may be coated after fabrication with either

33、 zinc or zinc alloy coating. In the case of zinc coating the purity of zinc shall be 98,5 % minimum (according to EN ISO 1461). Where an organic coating is specified it may be applied either on the uncoated netting or on the zinc or zinc alloy coated netting. BS EN 10223-2:2012EN 10223-2:2012 (E) 9

34、The netting may also be fabricated from zinc or zinc alloy coated wire with or without organic coating or with an extruded or sintered organic coating. Usual coating weight is according to EN 10244-2:2009, class A for Zn coating. Different coating weights may be agreed at time of order between purch

35、aser and supplier. 6 Requirements 6.1 General The netting shall be manufactured in the wire sizes, mesh sizes and widths as given in Table 2. The diameter of the wire characterizing the finished netting shall be the finished diameter in each case, either uncoated, zinc or zinc alloy coated or organi

36、c coated. Table 3 gives the relationship of the organic coated wire diameters to the core diameter. 6.2 Netting, zinc or zinc alloy coated after fabrication The netting shall meet the minimum values of coating mass and uniformity as stated in Table 2 and Table 4 of this European Standard. 6.3 Nettin

37、g made from zinc or zinc alloy coated wire Before fabricating into netting, the zinc or zinc alloy coated wire shall meet the minimum requirements of EN 10244-2:2009, class A for coating mass, adherence and where specified, the uniformity of the coating. Where samples are taken from the fabricated n

38、etting then the specified minimum coating mass requirement is reduced by 5 % and the specified dips by one half minute dip. For wire zinc or zinc alloy coated before fabrication, the twisted wire shall not break nor unwind in loading the netting up to 80 % of the breaking load of the wire (see Figur

39、e 4). NOTE Breaking load is the maximum force during the tensile test before breaking.
