5.1 The intended use of this practice is for 10- or 12-ft (3050 or 3660 mm) high chain-link fencing as complete enclosures around single or multiple tennis courts, or as backstops at either end of tennis courts.5.2 This practice is not intended for applications where fencing higher than 12 ft (3660 mm) is desired for a special application.5.3 Caution Regarding Windscreens—If wind screens are to be installed at the time of fence erection or at a later time, it is advisable to use stronger framework and parts and closer spacing of posts or back bracing depending upon the type of screening material to be used, area of fence to be covered, and local wind conditions. The Chain Link Fence Manufacturers Institute’s (CLFMI), Guide WLG 2445, provides the designer with the process to select the post size and post spacing.1.1 This practice covers fencing around tennis courts, built from various types of chain-link fabric and framework materials, and installation practices for same.1.2 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.1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.

This specification establishes the criteria for polymer privacy insert slats designed for insertion into chain link fabric after the chain link fence installation and privacy chain fabric having slats preinserted into chain link mesh during the chain link weaving process. It covers four types of polymer privacy insert slats: Type P-V consisting of polyethylene privacy insert slats hand inserted vertically into standard mesh chain link fabric after the fence installation; Type P-D consisting of polyethylene privacy insert slats hand woven diagonally into standard mesh chain link fabric after the fence installation; Type F-VDH consisting of modified fiberglass privacy insert slats hand woven, vertically, diagonally or horizontally into standard mesh chain link fabric after the fence installation; and Type PI-V consisting of privacy chain link fabric with vertical high density polyethylene privacy slats pre-inserted into the chain link mesh during the chain link weaving process. The standard addresses ordering information, privacy slat design configurations, weathering, chain link fence framework, tie wires and hog rings, and installation.1.1 This specification covers polymer privacy insert slats designed for insertion into chain link fabric after the chain link fence installation and privacy chain fabric having slats pre-inserted into chain link mesh during the chain link weaving process.1.1.1 Type P-V consists of polyethylene privacy insert slats hand inserted vertically into standard mesh chain link fabric after the fence installation.1.1.2 Type P-D consists of polyethylene privacy insert slats hand woven diagonally into standard mesh chain link fabric after the fence installation.1.1.3 Type F-VDH consists of modified fiberglass privacy insert slats hand woven, vertically, diagonally or horizontally into standard mesh chain link fabric after the fence installation.1.2 Type PI-V consists of privacy chain link fabric containing vertical high density polyethylene privacy slats pre-inserted into the chain link mesh during the chain link weaving process. Style 1a: Wider, 2 3/8 in. [60.3 mm] to 3 in. [76.2 mm] slats, pre-inserted into specially designed larger mesh. Style 1b: Type P-V friction fit slats pre-inserted into standard 2 in. [50 mm] chain link mesh.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.4 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.1.5 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.

This specification covers metallic-coated carbon steel wire for the manufacture of chain-link fence fabric and marcelled tension wire. Three coating types, namely: Type I (aluminized), Type II (galvanized), and Type III (zinc-aluminum-mischmetal alloy-coated), and five coating classes, namely: Class 3, Class 4, Class 5, Class 60, and Class 100, are covered. This specification does not cover the wire for chain-link fence when the coating is to be applied after the weaving process. The steel rod from which the wire is to be drawn shall be manufactured by the open-hearth, electric-furnace, or basic-oxygen process. The wire shall be cold-drawn, then metallic-coated at finished size to produce the specified mechanical properties such as breaking strength. Type I and Type III coatings shall be produced by a hot-dip process and Type II coating by either a hot-dip or an electrolytic process. The ingot or pig aluminum to be used for Type I coating shall conform to the impurity limits specified for copper and iron. Requirements for coated wire diameter, coating weight, coating adherence, and methods of chemical analysis and breaking strength test are detailed.1.1 This specification covers metallic-coated carbon steel wire used in the manufacture of chain-link fence fabric and marcelled tension wire.
