The diamond count ofa
7、 given fabric shall begin at the first completed diamond at oneedge and continue to the unfinished half or full opening at theother edge.3.1.3 knucklinga term used to describe the type of selvageobtained by interlocking adjacent pairs of wire ends and thenbending the wire ends back into a loop. The
8、loop shall beclosed or nearly closed to a measurement less than the diameterof the wire.3.1.4 twistinga term used to describe the type of selvageobtained by twisting adjacent pairs of wire ends together in aclose helix of 112 machine turns, which is equivalent to threefull twists, and cutting the wi
9、re ends at an angle. The wire endsbeyond the twist shall be at least14 in. (6.4 mm) long. Thistype of selvage is not used on fabric with a mesh size of lessthan 2 in. (50.8 mm).4.

Materials5.1 The wire from which the fabric is woven shall conformto all requirements of Specification A817 for Type III coating,in the class of coating specified (Class 1 or Class 2).6. Weave6.1 The wire sh
16、all be woven throughout in the form ofapproximately uniform square mesh, having parallel sides andhorizontal and vertical diagonals of approximately uniformdimensions. The top and bottom of the fabric shall be knuckledor twisted as specified in Section 10.6.2 Typical diamond count for each standard
17、height isshown in Table 1. Other diamond counts are permissibleprovided that they are consistent within a lot. The purchaserhas the option to specify the diamond count (4.1.5).7. Size of Mesh7.1 The size of mesh shall be as indicated in Table 2.7.2 The permissible variation from the specified size o
18、fmesh shall be 618 in. (63.2 mm) for all mesh sizes except 1in., and 6116 in. (61.6 mm) for 1 in. mesh size and under.7.3 The size of mesh shall be determined by measuring theminimum clear distance between the wires forming the parallelsides of the mesh and determined as the average of tworeadings t
19、aken at right angles to each other.8. Size of Wire8.1 Chain-link fabric shall be fabricated from wire diam-eters as listed in Specification A817, with a permissiblevariation from the specified diameter of the coated wire of60.005 in.

20、shed in the standardheights shown in Table 2. The height of fabric shall be theoverall dimension from ends of twists or knuckles. Thepermissible variation from the specified height shall be 61 in.(625 mm) for standard selvage.10. Selvage10.1 Unless otherwise specified by the purchaser, fabricswith 2
21、- or 218-in. (50- or 54-mm) mesh, in heights 60 in. (1520mm) and under shall be knuckled at both selvages. Fabric 72in. (1830 mm) high and over shall be knuckled at one selvageand twisted at the other.10.2 The selvages of fabrics with meshes of less than 2 in.(50 mm) shall be knuckled.NOTE 2Caution:
22、 Twisted selvages for fence fabric under 72 in. (1830mm) in height are not recommended because of consumer safety consid-erations.11. Weight of Coating11.1 The weight of Zn-5A1-MM alloy coating on the fabricmay be ordered in two coating weight classes as follows, inaccordance with Specification A817
23、.11.1.1 Class 1The weight of Zn-5A1-MM alloy coatingshall not be less than 0.6 oz/ft2(183 g/m2) of uncoated wiresurface.TABLE 1 Typical Diamond CountANOTE 1Other diamond counts are permitted (see 6.2).NOTE 2For fabric heights over 144 in., see 6.2.NOTE 3Variations to knuckled or twisted selvage may
