ASTM A992/A992M-11(2015)

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, titanium, 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 A6/A6M 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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
