【国外标准】 Standard Specification for Metallic-Coated, Steel-Woven Wire Fence Fabric

This specification covers metallic-coated steel-woven wire fence fabric having a series of horizontal (line) wires, with vertical (stay) wires either wrapped around the line wire (hinge joint) or fixed with another separate wire to the line wire (continuous stay fixed knot joint), forming rectangular openings. The fence fabric is suitable for use in fences for farm field enclosure (to keep domestic animals in or out), for wildlife and exotic animal control, for highway or railroad right-of-way fencing (to control access), and other similar uses. This specification covers fence fabric in various designs of tensile strength grades, namely: Grade 60, Grade 125, and Grade 175, metallic coating types, namely: Type A, Type Z, and Type ZA, and metallic coating classes, namely: Class 1, Class 3, Class 20, Class 40, and Class 80. The steel wire shall be coated prior to fabrication and the coating weight [mass] shall conform to the specified breaking strength and tensile strength. Requirements for construction including splicing and fence fabric length are detailed. Typical fence fabric dimensions for design numbers are illustrated. Tests for coating weight and breaking strength shall be performed.1.1 This specification covers metallic-coated steel fence fabric having a series of horizontal (line) wires, with vertical (stay) wires either wrapped around the line wire (hinge joint) or fixed with another separate wire to the line wire (continuous stay fixed knot joint), forming rectangular openings. The fence fabric is suitable for use in fences for farm field enclosure (to keep domestic animals in or out), for wildlife and exotic animal control, for highway or railroad right-of-way fencing (to control access), and other similar uses.1.2 This specification covers fence fabric in various designs, tensile strength grades, and metallic coating types and grades.1.3 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
