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.
