BS EN ISO 22476-4:2012 PDF Download

BS EN ISO 22476-4:2012 is a standard that specifies the equipment requirements, execution, and reporting for the Ménard pressuremeter test. This test involves the radial expansion of a tricell probe placed in the ground. The probe is inflated with liquid, causing soil displacement, and the pressure and volume expansion of the probe are measured to determine the stress-strain relationship of the tested soil.

The standard provides detailed information on the equipment required for the test, including the pressuremeter probe, pressure and volume control unit, connecting lines, injected liquid, and measurement and control systems. It also outlines the test procedure, including assembling the parts, calibration, probe placing, loading program, and safety requirements.

The test results are recorded and reported, including data sheets, field print-outs, corrected pressuremeter curves, and calculated results. The standard also includes terms, definitions, and symbols related to the Ménard pressuremeter test.

This standard is part of the wider ISO 22476 series on geotechnical investigation and testing, which also includes other field testing methods such as electrical cone and piezocone penetration test, dynamic probing, standard penetration test, flexible dilatometer test, borehole jack test, field vane test, weight sounding test, flat dilatometer test, and mechanical cone penetration test.
