Geotechnical investigation and testing. Field testing - Borehole jack test Ingestion-build-54484 Electrical safetyBS EN ISO 22476 7: 2012 specifies the equipment requirements, execution of and reporting on borehole jack tests. BS EN ISO 22476 7: 2012 specifies the procedure for conducting a borehole jack test in ground stiff enough not to be adversely affected by the drilling operation. Two diametral cylindrical steel loading plates are placed in the ground and opened by pressure. Pressure applied to, and associated opening of the probe are measured and recorded
