ASTM F1575/F1575M-24 PDF

Full title and description

Standard Test Method for Determining Bending Yield Moment of Nails, Spikes, and Dowel-type Threaded Fasteners — a test method that defines procedures to determine the bending yield moment (My) of driven and dowel-type fasteners and to calculate the corresponding bending yield strength (Fyb) used as an input for engineered connection design and capacity calculations.

Abstract

This test method specifies static loading procedures (commonly a three-point bending configuration) and measurement/analysis steps to obtain the bending yield moment of nails, spikes and dowel-type threaded fasteners and to compute bending yield strength (Fyb). Results are intended for use in laterally‑loaded connection design and related engineering calculations.

Scope

This standard covers procedures for determining bending yield moment and for calculating bending yield strength (Fyb) for nails, spikes, and dowel‑type threaded fasteners subjected to static bending. It provides the test arrangement, measurement methods and analysis conventions used to obtain the characteristic bending strength values required for engineered connection design.

Key topics and requirements

• Test specimen description and preparation (nails, spikes, dowel‑type threaded fasteners).
• Static bending test setup — typically a three‑point loading configuration to produce bending until yield.
• Measurement of load‑deflection behavior and determination of bending yield moment (My).
• Calculation of bending yield strength (Fyb) from My and fastener geometry (diameter/length) using the standard’s formulas.
• Use of the 5% offset or other specified conventions to define yield on the load‑deformation curve where applicable.
• Dual‑unit designation (F1575/F1575M) and reference to calibration and referenced practices (e.g., force/displacement verification standards cited).

Typical use and users

Structural and connection designers, fastener and nail manufacturers, independent testing laboratories, building code researchers, and materials engineers use this standard to produce repeatable bending yield data for use in design calculations, product development, quality control, and code compliance. Test laboratories offering fastener characterization commonly apply this method.

Related standards

This test method references and is used alongside other ASTM standards and practices (for example force/displacement calibration and related F16 fastener standards). Related ASTM documents include referenced calibration practices (E4) and other fastener and driven‑fastener standards (e.g., those covering driven fastener specifications and staple test methods). It is also used in conjunction with design documents such as national wood design standards and other F16 committee publications.
