Geotechnical investigation and testing - Geohydraulic testing - Part 4 : pumping tests

ISO 22282-4:2012 establishes requirements for pumping tests as part of geotechnical investigation service in accordance with EN 1997-1 and EN 1997-2.ISO 22282-4:2012 applies to pumping tests performed on aquifers whose permeability is such that pumping from a well can create a lowering of the piezometric head within hours or days depending on the ground conditions and the purpose. It covers pumping tests carried out in soils and rock.The tests concerned by ISO 22282-4:2012 are those intended for evaluating the hydrodynamic parameters of an aquifer and well parameters.

Geotechnical investigation and testing - Geohydraulic testing - Part 4 : pumping tests

This document establishes requirements for pumping tests as part of geotechnical investigation service in accordance with EN 1997-1 and EN 1997-2. This document applies to pumping tests performed on aquifers whose permeability is such that pumping from a well can create a lowering of the piezometric head within hours or days depending on the ground conditions and the purpose. It covers pumping tests carried out in soils and rock. The tests concerned by this document are those intended for evaluating the hydrodynamic parameters of an aquifer and well parameters, such as: — permeability of the aquifer, — radius of influence of pumping, — pumping rate of a well, — response of drawdown in an aquifer during pumping, — skin effect, — well storage, — response of recovery in an aquifer after pumping.

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.
