What ASTM specification should be specified for cold-formed steel studs?

The 2004 AISI Standard for Cold-Formed Steel Framing – General Provisions references ASTM A1003. The IBC 2003 references A653, A792, and A875. The General Notes on our drawings reference ASTM A446. Regarding ASTM specifications, ASTM A446 was replaced by ASTM A653. The relatively new ASTM A1003 was developed specifically for cold-formed steel framing, and provides a common standard for A653, A792, A875 and other materials as a means to simplify the process for the specifier and supplier. Therefore, the appropriate reference for framing members is ASTM A1003; however, materials furnished to A653, A792, and A875 would meet the requirements of the new A1003 standard. Note that the correct reference for steel deck and other coated non-framing member applications is ASTM A653.
