36、16120-2 and in a condition suitable for manufacture into netting. 5.2 Fabrication The netting may be coated after fabrication with either 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 specifi

37、ed it may be applied either on the uncoated netting or on the zinc or zinc alloy coated netting. DIN EN 10223-2:2013-02 EN 10223-2:2012 (E) 9 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

38、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 purchaser 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

39、the wire characterizing the finished netting shall be the finished diameter in each case, either uncoated, zinc or zinc alloy coated or organic 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 T

40、he 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 Netting 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

41、-2:2009, class A for coating mass, adherence and where specified, the uniformity of the coating. Where samples are taken from the fabricated netting 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

42、 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 Figure 4). NOTE Breaking load is the maximum force during the tensile test before breaking. DIN EN 10223-2:2013-02 EN 10223-2:2012 (E) 10 Key F 80 % of the braking
