Designation: D 5882 – 07
Standard Test Method for
Low Strain Impact Integrity Testing of Deep Foundations1
This standard is issued under the fixed designation D 5882; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1.1 This test method covers the procedure for determining
the integrity of individual vertical or inclined piles by measuring and analyzing the velocity (required) and force (optional)
response of the pile induced by an (hand held hammer or other
similar type) impact device usually applied axially and perpendicularly to the pile head surface. This test method is applicable
to long structural elements that function in a manner similar to
any deep foundation units (such as driven piles, augeured piles,
or drilled shafts), regardless of their method of installation
provided that they are receptive to low strain impact testing.
1.2 This standard provides minimum requirements for low
strain impact testing of piles. Plans, specifications, and/or
provisions prepared by a qualified engineer, and approved by
the agency requiring the test(s), may provide additional requirements and procedures as needed to satisfy the objectives
of a particular test program.
1.3 The text of this standard references notes and footnotes
which provide explanatory material. These notes and footnotes
(excluding those in tables and figures) shall not be considered
as requirements of the standard.
1.4 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
1.5 All observed and calculated values shall conform to the
guidelines for significant digits and rounding established in
Practice D 6026.
1.6 The method used to specify how data are collected,
calculated, or recorded in this standard is not directly related to
the accuracy to which the data can be applied in design or other
uses, or both. How one applies the results obtained using this
standard is beyond its scope.
1.7 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to
address all of the safety concerns, if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
dependent on the competence of the personnel performing it, and the
suitability of the equipment and facilities used. Agencies that meet the
criteria of Practice D 3740 are generally considered capable of competent
and objective testing/sampling/ inspection/etc. Users of this test method
are cautioned that compliance with Practice D 3740 does not in itself
assure reliable results. Reliable results depend on many factors; Practice
D 3740 provides a means of evaluating some of those factors.

3.1 Except as defined in 3.2, the terminology used in this
test method conforms with Terminology D 653.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 pile integrity, n—the qualitative evaluation of the
physical dimensions, continuity of a pile, and consistency of
the pile material.
3.2.2 pile impedance, n—the dynamic Young’s modulus of
the pile material multiplied by the applicable cross sectional
area of the pile and divided by the strain wave speed.
3.2.3 pulse echo method, n—test in which measurements of
the pile head velocity and force (force measurement optional)
are evaluated as a function of time.
3.2.4 transient response method, n—test in which the ratio
of velocity transform to force transform (force measurement
required) are evaluated as a function of frequency.
4. Significance and Use
4.1 Low strain impact integrity testing provides acceleration
or velocity and force (optional) data on slender structural
elements (that is, structural columns, driven concrete piles, cast
in place concrete piles, concrete filled steel pipe piles, timber

axis). The motion sensor is placed generally near the center of
the pile. Additional locations should be considered for piles
with diameters greater than 500 mm. The low strain impact
should be applied to the pile head within a distance of 300 mm
from the motion sensor. If the pile head is not accessible, as
when already integral with the structure, the sensor(s) may be
attached to the side of the pile shaft.
5.3 Signal Transmission—The signals from the sensors
shall be conveyed to the apparatus for recording, reducing, and
displaying the data, see 5.4, by a low noise shielded cable or
