National foreword This British Standard is the English language version of EN 10223-2:1997 published by the European Committee for Standardization (CEN). It supersedes BS 1485: 1983 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee ISE/26, Steel wire, which has the responsibility to: - aid enquirers to understand the text; - present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed, - monitor related international and European developments and promulgate them in the UK
A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references
The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

Definitions For the purpose of this standard the following definitions apply:
3
3.1 mesh size
mesh
the hexagonal netting consists of hexagonal shaped meshes, formed by twisting adjacent wires two by two, alternatively forming a twist to the right and to the left, the netting may have a border composed of one, two or more selvedge wires with a greater diameter than that used for the net; for widths above 50 cm or more stretching wires may be woven in the netting at equal distances (see Table 1) ©BSI
1998
3.3 twist
the tight helical winding of two wires around each other measured as each revolution of the two wires over 180”; in the case of regular twist, the wires rotate only in one direction, the minimum number of twists is three [see Figure 2a)]; in the case of reverse twist the two wires are first twisted in one direction and then in the other direction; in the short transition zone the two wires are straightened parallel, the minimum number of twists is 1% in each direction [see Figure 2b)] Table l - Recommended minimum number of stretching wires Roll width

Information to be supplied by the purchaser The 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) length of rolls d) mesh size; e) wire size; f) width; g) type - if no type is specified then either regular twist or reverse twist may be supplied; h) coating type; i) whether uniformity of coating is to be measured, j) inspection documentation requirements; k) agreed quality characteristics for testing (see clause 7). 4

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 Netting made from zinc or zinc alloy coated wire
Before fabricating into netting, the zinc or zinc ahoy coated wire shah meet the minimum requirements of prEN 102442, 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 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 3). A
6.1 Base metal
The base metal of the hexagonal netting shall be of a good commercial quality steel selected from EN 100161 and EN 10016-2 and in a condition suitable for manufacture into netting. 6.2 Fabrication
The netting may be coated after fabrication with either a zinc or zinc alloy coating. In the case of zinc coating the purity of zinc shall be 98.5 % minimum. Where an organic coating is specified it can be applied either on the uncoated netting or on the zinc or zinc ahoy coated netting. The netting can also be fabricated from zinc or zinc ahoy coated wire with or without organic coating or with an extruded or smtered organic coating. 6 Requirements 6.1 General
The netting shah 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 ahoy coated or organic coated. Table 3 gives the relationship of the organic coated wire diameters to the core diameter.

Other roll widths - by agreement. Zinc coated diameter in this table is the coated wire diameter in finished netting. These tolerances apply to the diameter of the zinc coated wire in finished netting. The tolerance on width shall be mesh size measurement. Tolerances on mesh size shall be mm for rabbit netting when specified. Coating mass netting coated after fabrication (see 8.1). For mesh width 75 mm and over, centre strands and selvedges should be by agreement.
