BS EN ISO 22476-1:2012 PDF Download

BS EN ISO 22476-1:2012 is a standard that deals with geotechnical investigation and testing in the field, specifically the electrical cone and piezocone penetration tests. These tests involve pushing a cone penetrometer into the soil at a constant rate of penetration, while measurements of cone resistance, sleeve friction, and pore pressures are recorded. The test results obtained from these tests can be used to interpret soil stratification, classify soil type, and evaluate engineering soil parameters.

The standard outlines the equipment requirements, test procedures, and reporting for electrical cone and piezocone penetration tests. It provides information on the selection of equipment and procedures, preparation of the test, pushing of the cone penetrometer, and registration of penetration length. It also includes guidelines on safety requirements, correction of parameters, and presentation of test results.

BS EN ISO 22476-1:2012 is part of a series of International Standards that define various field testing methods for geotechnical investigation. This particular standard focuses on the electrical cone and piezocone penetration tests. It partially supersedes previous British Standards and takes precedence over conflicting material in other standards. The standard is applicable to both electronic and mechanical measuring systems used in cone penetration tests.

ISO 22476 consists of multiple parts that cover different field testing methods, such as dynamic probing, standard penetration test, pressuremeter test, dilatometer test, jack test, field vane test, weight sounding test, and flat dilatometer test. Each part provides specific guidelines and requirements for the respective field testing method.
