ISO 22476-2:2005 specifies requirements for indirect investigations of soil by dynamic probing within the scope of the geotechnical investigations according to prEN 1997.
Abstract
Overview
EN ISO 22476-2:2005 - Geotechnical investigation and testing - Field testing - Part 2: Dynamic probing defines requirements for in‑situ as part of geotechnical site investigation (within the scope of EN 1997). The standard covers procedures for measuring soil and soft rock resistance by driving a into the ground with a falling hammer and recording penetration resistance as the number of blows per defined penetration. Dynamic probing provides a continuous profile (no samples recovered) and is intended primarily for qualitative profiling and comparative correlation with other tests.
