.png)
This standard is issued under the fixed designation A500/A500M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*1.1 This specification covers cold-formed welded and seam-less carbon steel round, square, rectangular, or special struc-tural tubular shapes for welded, riveted, or bolted constructionof bridges and buildings, and for general structural purposes.1.2 This tubing is produced in both welded and seamlesssizes with a periphery of 88 in. [2235 mm] or less, and aspecified wall thickness of 1.000 in. [25.4 mm] or less. GradeD requires heat treatment.NOTE 1—Products manufactured to this specification may not besuitable for those applications such as dynamically loaded elements inwelded structures, etc., where low-temperature notch-toughnessproperties, which are typically measured by Charpy Impact testing, maybe important. There are other ASTM standards that do have CVNrequirements and may be more suitable for those applications.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with thestandard. The inch-pound units shall apply unless the “M”designation of this specification is specified in the order.1.4 The text of this specification contains notes and foot-notes that provide explanatory material. Such notes andfootnotes, excluding those in tables and figures, do not containany mandatory requirements.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for the Development of International Standards, Guides and Recom-mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.2.
