7、ckling or of twisting the ends of the wires to form theselvage of the fabric. Variations to knuckled or twisted selvages are permissible.3.1.2 diamond countthe number of diamond openings from one edge of the fabric to the other. The diamond count of a givenfabric shall begin at the first completed d

8、iamond at one edge and continue to the unfinished (12) or full opening at the other edge.3.1.3 knucklingthe type of selvage obtained by interlocking adjacent pairs of wire ends and then bending the wire ends backinto a loop. The loop shall be closed or nearly closed to a measurement less than the di

9、ameter of the wire.3.1.4 twistingthe type of selvage obtained by twisting adjacent pairs of wire ends together in a close helix of 112 machineturns, which is equivalent to 3 full twists, and cutting the wire ends at an angle. The wire ends beyond the twist shall be at least14 in. 6.4 mm(6.4 mm) long

40、sizes smaller than 2 inches.11.2 On fabric galvanized after weaving, the weight of coating shall be determined on one or more pieces of wire removed fromthe fabric. These specimens may be of any length over 12 in. 300 mm(300 mm) and shall include both bends and straight sections,but shall not includ

Breaking Strength12.1 Wire constituting the fabric shall meet the minimum breaking strength listed in the Breaking Strength table of SpecificationA817 when tested in accordance with

42、 Test Methods and DefinitionsA370. Specimens to establish conformance to this requirementshall consist of individual pickets from a section of the fence fabric. The specimens shall be of sufficient length so as to be firmlygripped in the testing machine after straightening. The actual gage length (d

43、istance between jaws) of the specimen shall be limitedto the undeformed length of wire between the two adjacent straightened bends.13. Workmanship13.1Chain-link fence fabric shall be produced by methods recognized as good commercial practices. The zinc coating ongalvanized-after-weaving fabric shall

44、 be applied in a continuous process and shall not be applied to the fabric in roll form.13.2Excessive roughness, blisters, sal ammoniac spots, bruises, and flaking shall be noted. These and other defects, if presentto any considerable extent, shall provide a basis for rejection.13.1 Chain-link fence

45、 fabric shall be produced by methods recognized as good commercial practices. The zinc coating ongalvanized-after-weaving fabric shall be applied in a continuous process and shall not be applied to the fabric in roll form. Thegalvanized before-weaving fabric shall be woven using proven industry proc

46、edures to ensure a smooth consistent surface withoutpenetrating to the substrate, except at the selvage cut ends, see Note 3.13.2 Excessive roughness, blisters, sal ammoniac spots, bruises, flaking, and white rust shall be noted. The Galvanized AfterWeaving (GAW) process shall include the use of app

47、ropriate apparatus for producing galvanized fabric so as to prevent excessmaterial in the elbow joints that form the diamond mesh. The finished product shall exhibit free independent motion of overlappingwires that form the diamond mesh when in a free or installed state of tension. Any of the above

48、described defects listed in 13.1and 13.2 that will compromise the function of the product shall provide a basis for rejection.NOTE 3On fabric that is zinc-coated before weaving, rust formations on the cut ends of the wire at the fabric selvages are inherent characteristicsof this material and do not

49、 warrant rejection of the fabric.14. Standard Length of Rolls14.1 The standard length of roll shall be 50 ft 15.24 m(15.24 m) 6 1 % except as otherwise agreed upon at the time ofpurchase.14.2 The length of roll shall be determined by unrolling a roll of fabric on a flat surface and exerting tension by appropriatemeans to remove all slack. The tension applied shall not reduce the actual height of t
