ASTM A702-89(2006)

Standard Specification for Steel Fence Posts and Assemblies, Hot Wrought

ABSTRACT
This specification covers steel fence posts and assemblies manufactured from hot-wrought sections and intended for use in field and line fencing. Line posts shall be fabricated from steels A or B and assemblies from steels A, B, or C. The cross sections of the line post shall be T, U, or Y sections. One item from each lot shall be selected at random for testing. A lot shall consist of all posts or assemblies or both, of the same length offered for delivery at the same time.
SCOPE
1.1 This specification covers steel fence posts and assemblies manufactured from hot-wrought sections and intended for use in field and line fencing.
1.2 The posts are available in tee, channel, or U and Y-bar shapes or angle shapes and are furnished painted or galvanized, unless otherwise specified.
1.3 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.
