Standard Specification for Nonstructural Steel Framing Members

ABSTRACT
This specification covers nonstructural steel framing members in interior construction assemblies. Members shall be manufactured from steel and shall have a protective coating. Studs and rigid furring channels shall have a configuration and steel thickness such that the system in which they are used will carry the design transverse loads without exceeding either the allowable stress of the steel or the allowable design deflection. Members shall be manufactured in such a fashion as to minimize burrs and sharp edges. Penetration test shall be done for performance requirements, where members shall be capable of pulling the head of the screw below the surface of the gypsum board without spin out. Apparatus and materials shall satisfy the testing requirements of the specification.
SCOPE
1.1 This specification covers nonstructural steel framing members in interior construction assemblies.
1.2 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.
1.3 The following safety hazards caveat pertains only to the test methods portion, Sections 9 and 10, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
