Link to Active This link will always route to the current Active version of the standard. 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.

This test method will not give information regarding the pile bearing capacity. Last previous edition D — The results of the analysis may include a quantitative assessment of pile integrity.

Ensure that the pile head surface is accessible, above water, and clean of loose concrete, soil or other foreign materials resulting from construction.

Take, record, and display a series of velocity and force optional measurements. Active view current version of standard. Position the apparatus for applying the impact force so that the 58822 is applied axially with the pile and at a distance no larger than mm from the accelerometer. Average the suitable records of several impacts and apply necessary ampli?

Record the aztm of impacts for a speci? A superscript epsilon e indicates an editorial change since the last revision or reapproval.

No other units of measurement are included in this standard. The method works zstm on solid concrete sections, and has limited application to unfilled steel pipe piles, H piles, or steel sheet piles.

ASTM D – 16 – Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations

No other units of measurement are included in this standard. For piles with diameters larger than mm, attach the accelerometer at a minimum of three locations so that an integrity evaluation near the pile head may be made for each localized section of pile.

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 shaftsregardless of their method of installation provided that they are receptive to low strain impact testing. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Alternatively, the hammer may have an accelerometer attached and the measured acceleration may be converted to force using the hammer mass. The apparatus shall balance the velocity signal to zero between impact events. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement c such rights, are entirely their own responsibility.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Also, the test may identify minor impedance variations that may not affect the bearing capacity of the pile. The apparatus shall include r graphic display of velocity and force optionaland a data storage capability for retrieving records for further analysis.

This standard may involve hazardous materials, r, and equipment. The data are evaluated usually in the frequency domain. 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.

Attached to every digitized event should be identifying information names and descriptions, signal processing enhancement parameters, and date and time stamps. If the cause of poor data is not a motion 55882 attachment problem but rather is found to be a transducer aztm, repair or recalibrate it before further use. The combination of force and velocity may give additional information regarding the pile integrity near the pile head. ASTM D[1][1] pile integrity testing.

How one applies the results obtained using this standard is beyond its scope. Piles that are rigidly connected to a footing or superstructure are sometimes tested successfully although the evaluation often may be more difficult and may be inconclusive.

ASTM D 5882-16 Compliance Statement

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? It is the responsibility of the user of this standard to establish appropriate safety asm health practices and determine the applicability of regulatory limitations prior to use. This test method is applicable to long structural elements that function in a manner similar to foundation piles, regardless of their method of installation provided that they are receptive to low strain impact testing.

Use integrity evaluation from low strain tests together with other information, including pile installation procedures and observations, soil information, loading requirements, etc.

ASTM D – 16 Standard Test Method for Low Strain Impact Integrity Testing of Deep Foundations

Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. Alternately, the pile head force can be measured as well. Accelerometers shall be linear to at least 50 g. Do not use the records of impacts that cause the measurement device to overload. The accelerometer s should be placed at or near astk pile head and shall have their sensitive axis parallel with the pile axis.
