Geotechnical investigation and testing - Field testing - Part 2: Dynamic probing - Amendment 1 (ISO 22476-2:2005/A1:2011)
This document specifies requirements for indirect investigations of soil by dynamic probing as part of the geotechnical investigation services according to prEN 1997-1 and prEN 1997-2. This document covers the determination of the resistance of soils and soft rocks in situ to the dynamic penetration of a cone. A hammer of a given mass and given height of fall is used to drive the cone. The penetration resistance is defined as the number of blows required to drive the cone over a defined distance. A continuous record is provided with respect to depth but no samples are recovered.
Four procedures are included, covering a wide range of specific work per blow:
3 dynamic probing light (DPL): test representing the lower end of the mass range of dynamic equipment;
3 dynamic probing medium (DPM): test representing the medium mass range of dynamic equipment;
3 dynamic probing heavy (DPH): test representing the medium to very heavy mass range of dynamic equipment;
3 dynamic probing super heavy (DPSH): test representing the upper end of the mass range of dynamic equipment.
The test results of this document are specially suited for the qualitative determination of a soil profile together with direct investigations (e.g. sampling according to prEN ISO 22475-1) or as a relative comparison of other in situ tests. They may also be used for the determination of the strength and deformation properties of soils, generally of the cohesionless type but also possibly in fine-grained soils, through appropriate correlations. The results can also be used to determine the depth to very dense ground layers e.g. to determine the length of end bearing piles, and to detect very loose, voided, back-filled or infilled ground.

Geotehnično preiskovanje in preskušanje - Preskušanje na terenu - 2. del: Dinamični penetracijski poskus - Dopolnilo 1 (ISO 22476-2:2005/A1:2011)
Ta dokument določa zahteve za posredno preiskovanje prsti z dinamičnim penetracijskim poskusom kot delom storitev geotehničnega preiskovanja v skladu s standardoma prEN 1997-1 in prEN 1997-2. Ta dokument zajema določevanje odpornosti prsti in mehkih kamnin na dinamično penetracijo konusa na kraju samem. Za zabijanje konusa se uporabi kladivo z določeno maso in višino padca. Penetracijski odpor je določen kot število udarcev, ki so potrebni, da konus prodre do določene globine. Podatki o globini se neprekinjeno zapisujejo, vendar brez zbiranja vzorcev.
Vključeni so štirje postopki, ki zajemajo številna posebna dela na udarec:
– lahek dinamični penetracijski poskus (DPL): preskus, ki predstavlja dinamično opremo v spodnjem delu masnega razpona;
– srednji dinamični penetracijski poskus (DPM): preskus, ki predstavlja srednje težko dinamično opremo;
– težek dinamični penetracijski poskus (DPH): preskus, ki predstavlja srednje do zelo težko dinamično opremo;
– zelo težek dinamični penetracijski poskus (DPSH): preskus, ki predstavlja dinamično opremo v zgornjem delu masnega razpona.
Rezultati preskusa iz tega dokumenta so zlasti ustrezni za kvalitativno določevanje talnega profila skupaj z neposrednimi raziskavami (npr. vzorčenje v skladu s standardom prEN ISO 22475-1) ali kot relativna primerjava drugih preskusov na kraju samem. Uporabijo se lahko tudi za določevanje trdnostnih in deformacijskih lastnosti prsti, običajno nekohezivnega tipa, z ustreznimi korelacijami pa jih je mogoče uporabiti tudi za drobnozrnate prsti. Rezultati se lahko uporabijo tudi za določevanje globine zelo zbitih slojev zemljine npr. da se določi dolžina nosilnih pilotov in odkrijejo zelo rahle, luknjaste, ponovno nasute ali nasute zemljine.

Overview
SIST EN ISO 22476-2:2005/A1:2012 is a key European amendment to the geotechnical standard for field testing, focusing on dynamic probing. Developed by CEN and ISO, this amendment clarifies and updates technical requirements for dynamic probing as part of geotechnical investigations and testing. It outlines the correct equipment, execution, and reporting protocols for field dynamic probing to assess subsurface soil conditions. The standard supports compliance with EN 1997-1 and EN 1997-2 (Eurocode 7), ensuring harmonized geotechnical data collection for safe and reliable infrastructure design and construction.
Key Topics
- Equipment Requirements: Sets minimum specifications for dynamic probing equipment, including rods, cone tips, and drive systems, with procedures to ensure rod straightness and accurate calibration.
- Test Execution: Details proper field procedures for conducting dynamic probing, emphasizing control of driving rod inclination and guidelines for handling contaminated sites.
- Data Reporting: Specifies how to record and present blow count data objectively, without initial correction or adjustments, ensuring reliable comparison and evaluation.
- Quality Control and Calibration: Mandates annual calibration of free-fall penetrometers and verification of energy losses.
- Supplemental Investigations: Requires linkage of dynamic probing results with data from sampling (see ISO 22475-1) and ground identification standards (ISO 14688, ISO 14689).
- Documentation and Traceability: Updates references, terminology, and data recording formats for greater transparency and regulatory compliance.
Applications
SIST EN ISO 22476-2:2005/A1:2012 is widely applied in geotechnical site investigations for civil engineering and construction projects. Practical uses include:
- Foundation Assessment: Determining the suitability and stratification of soils for foundation design through quantitative dynamic probing results.
- Infrastructure Projects: Supporting road, tunnel, bridge, or embankment construction by profiling subsurface conditions efficiently.
- Environmental and Contaminated Sites: Specifies safety procedures for conducting probing where contamination is present, minimizing environmental risk.
- Urban Development: Assists in pre-construction risk assessment for buildings and infrastructure in complex ground conditions.
- Quality Assurance: Provides a standardized approach for geotechnical testing companies to ensure consistent, credible results that meet international best practices.
Reliable dynamic probing data, as structured by this standard, enhances safety margins, reduces unforeseen costs, and ensures regulatory acceptance of site investigation reports across Europe and globally.
Related Standards
For comprehensive geotechnical investigation and testing, refer to these related standards:

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
