High-strain testing instruments for deep foundations are testing devices that are used to evaluate the load-bearing capacity and integrity of foundation piles. Unlike low-strain testing, a large impact force is applied to the pile head to generate stress waves, thereby simulating actual pile loading conditions. The terms, symbols, basic requirements, and technical specifications for high-strain testing instruments are specified by this standard. Necessary requirements such as hardware requirements; software requirements; shock amplitude linearity error, impact zero drift, center frequency and bandwidth of the acceleration measurement system; its static performance and dynamic performance; dynamic range; channel conformity error; environmental robustness; and electromagnetic compatibility are also included. Testing methods, inspection rules, and marking requirements for high-strain testing instruments are also provided by this standard.

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
P3456.3
Standard for Testing instruments for Deep Foundations–Part 3: Nonmetallic ultrasonic testing instruments
This standard specifies the technical requirements, test methods, and inspection procedures for nonmetallic ultrasonic testing instruments used in deep foundation engineering, together with provisions regarding labeling, packaging, transportation, and storage. The standard establishes performance criteria, testing methodologies, and procedures for compliance verification applicable to instruments operating on the basis of the ultrasonic transmission method and the rebound comprehensive method.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
3456.1-2025
IEEE Standard for Testing Instruments for Deep foundations - Part 1:Low-strain Testing Instruments
The integrity and continuity of concrete piles after installation are evaluated using low-strain testing instruments for deep foundations, which are non-destructive testing devices. They are among the most commonly used tools in pile quality assessment. The terms, symbols, basic requirements, and technical specifications for low-strain testing instruments are specified by this standard. Necessary requirements such as hardware requirements, software requirements, vibration amplitude linearity, the center frequency and bandwidth of the acceleration measurement system, dynamic range, environmental robustness, and electromagnetic compatibility should also be included. Testing methods, inspection procedures, and marking for low-strain testing instruments are also provided by this standard.
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.
No Inactive-Reserved Standards
