Standard EN Sample
Geotechnical Investigation and Testing - Field Testing - Borehole Jack Test
Also Known As:
BS EN ISO 22476-7:2012 is a standard that specifies the requirements for equipment, execution, and reporting of borehole jack tests. These tests are conducted in ground stiff enough to not be affected by the drilling operation.
The standard outlines the procedure for conducting a borehole jack test, which involves placing two cylindrical steel loading plates in the ground and applying pressure to open them. The pressure applied and the associated displacement of the probe are measured and recorded to obtain a stress-displacement relationship of the ground.
The contents of the standard include a scope, normative references, terms, definitions, and symbols, equipment requirements, test procedure, test results, and reporting. The reporting section covers the general guidelines for reporting test results, including the choice of axis scaling and presentation of the results.
BS EN ISO 22476-7:2012 is part of a series of standards that cover various field testing techniques for geotechnical investigation and testing. It is the UK implementation of the corresponding European standard EN ISO 22476-7:2012 and partially supersedes the British Standard BS 5930:1999+A2:2010.
