ASTM D 1143 : 1981 : R1994 : EDT 1

1.1 This test method covers procedures for testing vertical or batter piles individually or groups of vertical piles to determine response of the pile or pile group to a static compressive load applied axially to the pile or piles within the 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:

Section Referenced Documents 2 Apparatus for Applying Loads 3 Apparatus for Measuring Movements 4 Loading Procedures 5 Procedures for Measuring Pile Movements 6 Safety Requirements 7 Report 8 Precision and Bias 9

1.2 The values stated in inch-pound units are to be regarded as the standard.

Note 1-Apparatus and procedures designated "optional" are to be required only when included in the project specifications or 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 indicate mandatory provisions. Notes, illustrations, and appendixes included herein are explanatory or advisory. Note 2-This test method does not include the interpretation of test results or the application of test results to foundation design. See Appendix XI 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 method indicates rapid progressive settlement of the pile or pile group under a constant load.

1.3 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.
