Full title and description

ASTM D1143/D1143M-20e1 — Standard Test Methods for Deep Foundation Elements Under Static Axial Compressive Load. This standard specifies field procedures, apparatus, and reporting requirements for measuring axial deflection and load-deflection behavior of individual vertical or inclined deep foundation elements (single elements or groups) when subjected to static axial compressive loads, and includes the 2020 designation with the e1 editorial/errata update.

Abstract

Provides minimum requirements and optional procedures for performing static axial compressive load tests on deep foundation elements (drilled shafts, cast-in-place piles, driven piles, barrettes, etc.). The methods measure axial deflection versus applied load and describe common loading procedures (Quick Test, Maintained Test, Constant Rate of Penetration), instrumentation, and reporting so results can be used to evaluate element capacity and load-settlement response.

Scope

The standard covers test methods to measure axial deflection of individual vertical or inclined deep foundation elements or element groups under static axial compressive loading. It applies to all practical deep foundation element types (drilled shafts, augered cast-in-place piles, driven piles, timber, steel, barrettes, etc.) and provides minimum mandatory requirements; project-specific plans or engineer-approved deviations may add further requirements. The standard is intended for use when field-verification of axial capacity and load-deflection behavior is required but does not by itself predict long-term performance of entire foundation systems.

Key topics and requirements

• Measurement of axial deflection vs. applied static compressive load (load–settlement curves).
• Loading procedures: Quick Test, Maintained (incremental) Test, Constant Rate of Penetration (CRP) Test and guidance on selecting procedures.
• Apparatus and instrumentation: hydraulic jacks or reaction systems, calibrated load cells, reference beams, displacement gauges, and supporting frames; design and approval of loading apparatus by a qualified engineer.
• Requirements for test planning, safety, test control, and data reporting (including limitations and recommended interpretations by qualified geotechnical engineers).
• Guidance on extrapolating results to non-tested elements and notes on factors affecting interpretation (creep, consolidation, group effects).

These topics and mandatory/recommended provisions are summarized from the ASTM standard text.

Typical use and users

Used by geotechnical and structural engineers, specialty testing contractors, construction firms, owners/developers, and testing laboratories to verify pile/shaft capacity, assess load–settlement performance, qualify foundation element installation, and support foundation design decisions. Agencies meeting ASTM Practice D3740 competence criteria are commonly engaged to perform tests; a qualified geotechnical engineer should interpret results.

FAQ

Q: What is this standard?

A: ASTM D1143/D1143M-20e1 is the ASTM standard that sets out field test methods for measuring axial deflection and evaluating static axial compressive capacity of deep foundation elements (piles, shafts, barrettes, etc.).

Q: What does it cover?

A: It covers test procedures, required apparatus and instrumentation, loading sequences (including Quick Test, Maintained Test, and CRP), safety and reporting requirements, and clarifies mandatory versus optional provisions; it does not, by itself, provide full interpretation for long-term system performance (that requires engineering judgment).

Q: Who typically uses it?

A: Geotechnical engineers, specialized field-testing contractors, construction quality assurance teams, and testing laboratories use the standard to verify element capacity and load–settlement behavior for foundation design and acceptance.

Q: Is it current or superseded?

A: The D1143/D1143M-20e1 edition (originally issued 2020 with an e1 editorial update) is listed as an active ASTM standard and had a maintenance/update entry noted in June 2024; users should confirm the current active status through ASTM before purchase or application.

Q: Is it part of a series?

A: The designation D1143/D1143M denotes paired inch-pound (D1143) and metric (D1143M) units in a single document. It is part of ASTM Committee D18’s suite of foundation and pile testing standards and is frequently used together with related practices (for agency qualification, instrumentation, and alternative test methods).

Q: What are the key keywords?

A: Deep foundation, pile load test, static axial load, load–settlement curve, load cell, reaction frame, drilled shaft, cast-in-place pile, constant rate of penetration.
