19、 Dimensions and Permissible Variations7.1 The size of the mesh openings in the netting shall be 1in. (25 mm) or 2 in. (51 mm) as specified (see Table 1). Theopening tolerance shall be 618 in. (3.2 mm) when measuredacross the flats.7.2 The height of the netting and fence fabrics (center tocenter dist
20、ance between top and bottom wires) shall not varymore than 61 in. (25 mm).7.3 The tolerance for fence fabrics individual line and staywire spacing shall be 638 in. (9.5 mm). This does not alter theoverall height of the fabric as designated in 7.2.7.4 The length tolerance for all styles of netting an

No limits are placed onout-of-roundness of wire in the fabric.8. Workmanship8.1 Splicing
22、of individual line wires by means of a wrapjoint or an electric butt weld is permitted. The maximumnumber of line wire splices or joints shall not exceed one halfof the number of line wires in any roll of fence. Such splices orjoints shall be made in a workmanlike manner.8.2 Patching of voids in the
23、 poultry netting by means ofhand weaving is permitted. Such repair shall be made in aworkmanlike manner.8.3 The fence fabrics shall have uniformly wrapped jointsand all stay wires shall be properly spaced and substantiallyperpendicular to the line wires.9. Sampling9.1 SamplesFor the purpose of tests
24、, select at random, oneroll from every 50 rolls or fraction thereof in a lot or a total ofseven rolls, whichever is less. A lot shall consist of all the rollsof a single design offered for delivery at the same time.9.2 Test Specimens for Poultry NettingSpecimens fortesting shall consist of 1 ft2(0.0
25、9 m2) selected at any point inthe width of the netting and taken from the end of the roll, butnot to include the selvage. Subject a specimen from eachsample to tests for weight of coating in accordance withSection 10.9.3 Test Specimens for Fence FabricCut a length offabric, approximately 3 ft or 1 m
26、 long, from the end of thesample roll to include at least three of the vertical (stay) wires.The test specimens for weight of coating determination shallconsist of a number of lengths cut from a single wire,excluding all wire knots, wraps, and welded sections, such thatthe total length of wire test
27、is at least 6 in. (152 mm), butpreferably about 12 in. (305 mm). Test at least six testspecimens for weight of coating in accordance with Section 10.9.3.1 Select as follows:9.3.1.1 One specimen from the top or bottom wires,9.3.1.2 Three specimens from horizontal (line) wires otherthan the top or bot
28、tom wires, and9.3.1.3 Two specimens from vertical (stay) wires.9.4 Instead of testing wire from the completed fence fabricin accordance with 9.2 or 9.3, the manufacturer may elect toestablish compliance with Section 10 of this specification bytests made on wire prior to fabrication. If the manufactu
29、rermakes this election, the purchaser still reserves the right to testwire from the completed fence fabric.10. Weight of Coating10.1 The class of coating for netting shall be specified bythe purchaser and shall be in accordance with the classes ofcoating prescribed in Table 4.10.2 The weight of coat

34、the computation of the surface area of the specimens.TABLE 2 Design Numbers of Poultry and Garden Fence (Furnished in 10-rod Rolls)NOTE 1Design Numbers: In accordance with trade practice, each design of fence is expressed by a group of three numbers separated by a dash (-).The first number of the gr
35、oup contains either three or four digits. In a number containing four digits, the first two represent the number of horizontal wires;and the second two the total height in inches. Where three digits are used, the first one represents the number of horizontal wires, and the remaining twothe height in
36、 inches. The second number of the group indicates the spacing of the stay (vertical) wires, in inches. The third number of the group indicatesthe gauge of the intermediate line (horizontal) wires and of the stay wires. It does not apply to the top and bottom horizontal wires, the gauge for whichis s
