Applicable to tests conducted both above and below the groundwater table. Purpose: To determine the local permeability coefficient (
Here’s a sample review for the standard (PDF format):
Focuses on "open systems" where water level is free to move or is maintained at a specific head within a borehole. 🧪 Core Test Methods

or other national standards bodies adopting the EN ISO framework.
Specifics on pumps, sensors, and borehole construction.
This method is used when the test section is at the very bottom of an uncased borehole. Water is forced into or removed from the formation through the open end of the drilling string. Common procedures include: Applicable to tests conducted both above and below
BS EN ISO 22282-2 is a crucial European standard adopted from the international ISO framework. It specifies the requirements for performing field permeability tests by the open hole method (also known as slug tests or bailer tests) in soils and rock. This part of the ISO 22282 series focuses on tests conducted in a single borehole without packers, providing essential data for hydrogeological and geotechnical projects.

The standard demands high precision. It specifies requirements for: or other national standards bodies adopting the EN
: Testing can be executed in both saturated and unsaturated zones , measuring ground properties both above and below the native groundwater table. Core Test Methods Covered in the Standard
Water is injected into or withdrawn from the borehole at a rate adjusted to maintain a fixed water level (hydraulic head). Data collection: The flow rate ( ) needed to keep the head stable is recorded against time. Variable Head Method
: Utilized in open holes or through the bottom of a casing string where packers are not required to isolate the test zone. Purpose : To determine the local hydraulic conductivity ( -value) of the ground. Key Testing Methods Defined in the Standard
