Standard Test Method for
Individual Piles Under Static Axial Tensile Load1
This standard is issued under the fixed designation D 3689; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
a superscript epsilon (e) indicates an editorial change since the last revision or reapproval
1. Scope
1.1 This test method covers procedures for testing vertical
or batter piles, individually or in groups, to determine a response
of the pile or pile group to a static tensile load applied axially
to the pile or pile group. This test method is applicable to all
deep foundation units that function in a manner similar to piles,
regardless of their method of installation. This test method is
divided into the following sections:

1.2 This test method only describes procedures for testing
single piles or pile groups. It does not cover the interpretation
or analysis of the test results or the application of the test
results to foundation design. See Appendix X1 for comments
regarding some of the factors influencing the interpretation of
test results. A qualified geotechnical engineer should interpret
the test results for predicting pile performance and capacity.
The term“ failure”, as used in this test method, indicates a rapid
the progressive movement of the pile or pile group in the direction
of loading under a constant or decreasing load.
1.3 Apparatus and procedures designated “optional” are to
be required only when included in the project specifications
and, if not specified, may be used only with the approval of the
engineer responsible for the foundation design. The word
“shall” indicates a mandatory provision and “should” indicates
a recommended or advisory provision. Imperative sentences.
