Geotechnical investigation and testing - Geohydraulic testing - Part 3 : water pressure tests in rock

ISO 22282-3:2012 specifies the requirements for water pressures tests (WPT) carried out in boreholes drilled into rock as part of geotechnical investigation and testing according to EN 1997-1 and EN 1997-2. The tests are used to investigate the following: hydraulic properties of the rock mass, which are mainly governed by discontinuities; absorption capacity of the rock mass; tightness of the rock mass; effectiveness of grouting; geomechanical behaviour, e.g. hydrofracturing, hydrojacking.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
