ISO 22476-6:2018 PDF Download

ISO 22476-6:2018 is a standard that provides guidelines for conducting self-boring pressuremeter (SBP) tests and reporting the results. These tests are used as part of geotechnical investigation services in accordance with EN 1997-1 and EN 1997-2.

The purpose of SBP tests is to measure the deformation of soils and weak rocks in situ by using a cylindrical flexible membrane. This membrane expands and contracts under pressure, allowing for the measurement of soil parameters and properties.

The standard specifies the equipment requirements for conducting SBP tests, including the pressuremeter equipment itself and ancillary equipment such as pumps and gauges. It also provides guidance on the execution of the tests, including the preparation of the borehole, installation of the pressuremeter, and application of the pressure cycles.

In addition, ISO 22476-6:2018 outlines the requirements for reporting the test results, including the measurement data, interpretation of the results, and any corrections or adjustments made. The standard aims to ensure consistency and accuracy in the execution and reporting of SBP tests, providing reliable data for geotechnical investigations and engineering design.
