ASTM A992/A992M-06a

Standard Specification for Structural Steel Shapes

ABSTRACT
This specification covers rolled steel structural shapes for use in building framing or bridges, or for general structural purposes. Heat analysis shall be used to determine the percentage of carbon, manganese, phosphorus, sulfur, vanadium, nickel, chromium, molybdenum, columbium, and copper for the required chemical composition. Tension test shall be used to evaluate the required tensile properties such as tensile strength, yield strength and elongation.
SCOPE
1.1 This specification covers rolled steel structural shapes for use in building framing or bridges, or for general structural purposes.
1.2 Supplementary requirements are provided for use where additional testing or additional restrictions are required by the purchaser. Such requirements apply only when specified in the purchase order.
1.3 When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be utilized. See Appendix X3 of Specification A 6/A 6M for information on weldability.
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system is to be used independently of the other without combining values in any way.
1.5 The text of this specification contains notes or footnotes, or both, that provide explanatory material; such notes and footnotes, excluding those in tables and figures, do not contain any mandatory requirements.
