The diamond count ofa given fabric
7、 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 loop shall be
8、closed 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 wire ends at an
9、 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 shall be wove
16、n 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 height issh
17、own 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 ofmesh shall
18、 be 618 in. (63.2 mm) for all mesh sizes except 1in., and 6116 in. (61.6 mm) for 1 in. mesh size.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 taken at right angles
19、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. (60.13 mm).9. Height of Fabric9.1 Chain-link fabric shall be furnished in the standardh
20、eights 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- or 218-in. (50- or
21、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: Twisted selvages for
22、 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 A817.11.1.1 Class 1The we
23、ight of Zn-5A1-MM alloy coatingshall not be less than 0.6 oz/ft2(183 g/m2) of uncoated wiresurface.11.1.2 Class 2The weight of Zn-5A1-MM alloy coatingshall not be less than 1.0 oz/ft2(305 g/m2) of uncoated wiresurface.11.2 The weight of coating shall be determined in accor-dance with Test Method A90
24、/A90M.12. Workmanship12.1 Chain-link fence fabric shall be produced by methodsrecognized as good commercial practices. The zinc-5 %aluminium-mishcmetal before-weaving fabric shall be wovenusing proven industry procedures to ensure a smooth consistentsurface without penetrating to the substrate, exce
25、pt at theselvage cut ends, see Note 3.12.2 Excessive roughness, blisters, and flaking shall benoted. These and other defects, if present to any considerableextent, shall provide a basis for rejection.NOTE 3Rust formations on the cut ends of the wire at the fabricselvages are inherent characteristics

Standard Length of Rolls13.1 The standard length of roll shall be 50 ft (15.24 m) 61 % except as otherwise agreed upon at the time of purchase.13.2 The length of roll shall be determined by unrolling aroll of fabric on a flat surface and exer
30、ting tension byappropriate means to remove all slack. The tension appliedshall not reduce the actual height of the fabric by more than116in./ft (5.3 mm/m) of height or by more than12 in. (12.7 mm),whichever is less.14. Sampling and Number of Tests14.1 One roll from every 50 rolls or fraction thereof
31、 in a lotshall be taken at random as a sample for test purposes. In nocase shall less than two samples be tested, except when the lotis less than 10 rolls, only one roll shall be selected for thesample.14.2 Sample rolls selected shall be inspected for weave(Section 6), size of mesh (Section 7), diam
32、ond count (6.2), wiresize (Section 8), height of fabric (Section 9), selvage (Section10) and length (Section 13).14.3 If any specimen tested fails to meet the requirements ofthis specification, the roll represented by the specimen shall berejected and two additional rolls shall be inspected, both of
33、which shall meet the requirements in every respect; otherwise,the lot represented by the samples may be rejected.15. Inspection15.1 Unless otherwise specified in the purchase order orcontract, the manufacturer is responsible for the performanceof all inspection and test requirements specified in thi
