P3456.1

Standard for Testing Instruments for Deep foundations - Part 1:Low-strain Testing Instruments

This standard specifies general requirements for the measurement and analysis system of testing instruments, covering the composition, configurations, working conditions, typical performance, test methods, and inspection rules for judging the integrity of deep foundations and the determination of defect severity and defect locations of deep foundations. A deep foundation is a foundation that is installed to a significant depth greater than 3 meters to handle a specific load. However, the depth depends on the engineering construction and geological conditions. A low-strain testing instrument utilizes low-energy (a few newtons to several hundred newtons) transient-state or steady-state excitation to induce low-amplitude vibration of the pile under elastic deformation. It utilizes wave theory to determine pile defects. The standard specifications include classification, measurement system, analysis system, and safety requirements.

P3456.2
Standard for Testing instruments for Deep Foundations - Part 2: High-strain Testing Instruments

This standard specifies general requirements for the measurement and analysis system of testing instruments, covering the composition, configurations, working conditions, typical performance, test methods, and inspection rules for judging the compressive bearing capacity and integrity of deep foundations. A deep foundation is a foundation that is installed to a significant depth greater than 3 meters to handle a specific load. However, the depth depends on the engineering construction and geological conditions. A high-strain testing instrument utilizes high-energy (tens to hundreds of kilonewtons) transient-state excitation to cause relative displacement between the pile and soil. It utilizes wave inversion theory to reveal the performance of the pile-soil system in elastic-plastic deformation, evaluate the quality of the pile body, and analyze the ultimate bearing capacity of the pile. The standard specifications include classification, measurement system, analysis system, and safety requirements.

No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
