Standard EN Sample
Geotechnical Investigation and Testing: Field Testing - Flexible Dilatometer Test
Also Known As:
BS EN ISO 22476-5:2012 is a standard that specifies the requirements for conducting flexible dilatometer tests for geotechnical investigation and testing. The standard outlines the equipment requirements, test procedure, and reporting of test results.
The standard starts by providing an overview of the scope and normative references. It then defines the terms, symbols, and abbreviations used in the standard. The equipment requirements section covers various aspects such as the dilatometer probe, pressure control and displacement measuring units, and measurement and control accuracy.
The test procedure section explains the safety requirements, assembly of parts, calibration of the testing device, pocket drilling and device placing, and the execution of the test. It also discusses the back-filling of the borehole after the test is completed.
The standard provides equations and guidelines for interpreting the test results. It discusses loading tests, constant pressure tests, and the presentation of uncorrected and corrected graphs. The test report section outlines the general requirements for reporting the test results, including the choice of axis scaling and the presentation of test results.
BS EN ISO 22476-5:2012 is part of the larger ISO 22476 series, which covers various field testing methods for geotechnical investigation and testing. This particular standard focuses specifically on the flexible dilatometer test. It partially supersedes the British Standard BS 5930:1999+A2:2010 and is the UK implementation of EN ISO 22476-5:2012.
