The American Iron and Steel Institute[2] (AISI) published several new test standards, all of which have been approved by the American National Standards Institute[3] (ANSI).

“The AISI test standards are updated every five years to facilitate research and development leading to improved state-of-the-art solutions in steel for the construction market,” said Jay Larson, managing director, AISI’s construction technical program. “We also updated the titles for the 2017 series, so they have a more consistent format but differ slightly from the titles in the previous series.”

The suite of test standards is often referenced in industry acceptance criteria, providing a level playing field for establishing the performance characteristics of unique products and applications.”

Updated standards include:

• AISI S901-17, Test Standard for Determining the Rotational-lateral Stiffness of Beam-to-Panel Assemblies (revision of AISI S901-13);
• AISI S902-17, Test Standard for Determining the Effective Area of Cold-formed Steel Compression Members (revision of AISI S902-13);
• AISI S903-17, Test Standard for Determining the Uniform and Local Ductility of Carbon and Low-alloy Steels (revision of AISI S903-13);
• AISI S904-17, Test Standard for Determining the Tensile and Shear Strengths of Steel Screws (revision of AISI S904-13);
• AISI S905-17, Test Standard for Determining the Strength and Deformation Characteristics of Cold-formed Steel Connections (revision of AISI S905-13);
• AISI S906-17, Test Standard for Determining the Load-carrying Strength of Panels and Anchor-to-Panel Attachments for Roof or Siding Systems Tested in Accordance with ASTM E1592 (revision of AISI S906-13);
• AISI S907-17, Test Standard for Determining the Strength and Stiffness of Cold-formed Steel Diaphragms by the Cantilever Test Method (revision of AISI S907-13);
• AISI S908-17, Test Standard for Determining the Flexural Strength Reduction Factor of Purlins Supporting a Standing Seam Roof System (revision of AISI S908-13);
• AISI S909-17, Test Standard for Determining the Web Crippling Strength of Cold-formed Steel Flexural Members (revision of AISI S909-13);
• AISI S910-17, Test Standard for Determining the Distortional Buckling Strength of Cold-formed Steel Hat-shaped Compression Members (revision of AISI S910-13);
• AISI S911-17, Test Standard for Determining the Flexural Strength of Cold-formed Steel Hat-shaped Members (revision of AISI S911-13);
• AISI S912-17, Test Standard for Determining the Strength of a Roof Panel-to-Purlin-to-Anchorage Device Connection (revision of AISI S912-13);
• AISI S913-17, Test Standard for Determining the Strength and Deformation Behavior of Hold-downs Attached to Cold-formed Steel Structural Framing (revision of AISI S913-13); and
• AISI S914-17, Test Standard for Determining the Strength and Deformation Behavior of Joist Connectors Attached to Cold-formed Steel Structural Framing (revision of AISI S914-13).

AISI also recently published a new test standard in its S900 series, AISI S919-17, Test Standard for Determining the Flexural Strength and Stiffness of Cold-formed Steel Nonstructural Members.

“This test standard was developed by AISI’s Committee on Specifications and is intended for adoption and use when performance testing of the cold-formed steel nonstructural member is required,” said Larson. “It can be used to determine the nominal flexural strength (resistance) for both local buckling and distortional buckling failure modes. The test standard provides an alternative approach to evaluating the flexural strength and stiffness of nonstructural members.”

AISI’s codes and standards work is conducted under the Construction Market Council of the Steel Market Development Institute (SMDI), which promotes the use of steel in the construction industry through the development of innovative materials, applications, and solutions for users.
