AISI Publishes Two New Cold-Formed Steel Framing Test Standards


WASHINGTON, D.C. – The American Iron and Steel Institute (AISI) has published two new cold-formed steel test standards: 1) “AISI S921-19, Test Standard for Determining the Strength and Stiffness of Cold-Formed Steel Truss Assemblies and Components,” and 2) “AISI S922-19, Test Standard for Determining the Strength and Stiffness of Bearing-Friction Interference Connector Assemblies in Profiled Steel Panels.” Both are available for free download at

AISI’s Committee on Specifications developed AISI S921-19 to establish procedures for confirmatory and performance testing of the strength and serviceability of cold-formed steel truss assemblies and components. It is applicable to roof and floor trusses, whether built as component assemblies or fabricated on site; and is useful for laboratory or in situ testing. AISI S922-19 was developed to provide a test method for determining the strength and stiffness of bearing-friction interference connector assemblies installed in cold-formed profiled steel panels including steel deck and steel deck-slabs.

AISI test standards are updated every five years and facilitate research and development leading to improved state-of-the-art solutions in steel for the construction market. They are often referenced in industry acceptance criteria and lead the way in establishing the performance characteristics of unique products and applications.

AISI serves as the voice of the North American steel industry in the public policy arena and advances the case for steel in the marketplace as the preferred material of choice. AISI also plays a lead role in the development and application of new steels and steelmaking technology. AISI’s membership is comprised of integrated and electric furnace steelmakers, and associate members who are suppliers to or customers of the steel industry.
