The American Iron and Steel Institute (AISI) published two cold-formed steel test standards:

• “AISI S921-19, Test Standard for Determining the Strength and Stiffness of Cold-Formed Steel Truss Assemblies and Components”
• “AISI S922-19, Test Standard for Determining the Strength and Stiffness of Bearing-Friction Interference Connector Assemblies in Profiled Steel Panels”

AISI stated its 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 built as component assemblies or fabricated on site. AISI S922-19 provides 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.
