2、on, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the strength and protectivecoating requirements for industrial steel chain
3、link fenceframework. Maximum allowable heights of framework andpost spacing are to be based on chain link fence fabric meshsize and gages, and specified wind loads. Post spacings are notto exceed 10 ft. (For additional information, see CLFMI GuideWLG2445.)1.1.1 Caution Regarding WindloadIf additives
4、 to thefence, such as windscreen, inserts, or signage are required, it isadvisable to use stronger framework and fittings, to reduce theon-center spacing of posts, or to add back bracing. Factors toconsider when determining windload include the type ofscreening material to be used, area of fence to
5、be covered andlocal wind conditions.1.2 Posts and rails may have any cross-sectional shapemeeting the requirements herein. The shapes may be formedand welded, cold formed, hot rolled, or extruded.1.3 The values in inch-pound units are to be regarded as thestandard. The values stated in SI units are

Strength Calculations6.1 The strength of a structural member can generally bepredicted from established engineering principles. The intentof this section is to provide criteria by which alternate desi
42、gnscan be judged to provide adequate strength without prematurefailure by local buckling. Accordingly, the criteria of 6.2 and6.3 shall be satisfied even though, in general, only one willgovern a particular design.6.2 The elastic bending strength equals the yield strengthtimes the section modulus of
43、 the entire cross section.6.2.1 The yield strength may be considered to be either: (1)the minimum specified yield strength for material used to forma part, or (2) the value determined from tension tests performedin accordance with Test Method E 8. The specimen may be cuteither from material before f
