ASTM F1575- Standard Test Method for Determining Bending Yield Moment of Nails

 

ASTM F1575 covers procedures for determining the bending yield moment of nails when subjected to static loading.

It is intended only for nails used in engineered connection applications, in which a required connection capacity is specified by the designer.

ASTM F1575  / Significance and Use

Nails are a common mechanical fastener in wood structures. Engineering design procedures used to determine the capacities of laterally-loaded nailed connections

currently use a yield theory to establish the nominal resistance for laterally-loaded nailed connections that are engineered.

In order to develop the nominal resistance for laterally-loaded nailed connections, the bending yield moment must be known.

ASTM F1575 / Apparatus

Testing Machine—Any suitable testing machine capable of operation at a constant rate of motion of its movable head and having an accuracy of ± 1 % when

calibrated in accordance with Practices ASTM E4.

Cylindrical Bearing Points—Any cylindrical metal member capable of supporting the test specimen during loading without deforming and having

diameter (d) = 0.375 in. [9.53 mm].

Cylindrical bearing points shall be free to rotate as the test specimen deforms.

Cylindrical Load Point—Any cylindrical metal member capable of loading the test specimen without deforming  and having diameter (d) = 0.375 in. [9.53 mm].

Recording Device—Any device with at least a reading of 0.001 in. [0.01 mm] and any suitable device for measuring the load on the test specimen during deformation

ASTM F1575 / Summary of Test Method

Test specimens are evaluated to determine capacity to resist lateral bending loads applied at a constant rate of deformation with a suitable testing machine.

The load on the test specimen at various intervals of deformation is measured.

Supplementary physical properties of the test specimen are also determined.

*** Before conducting ASTM F1575 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
