The standard defines the equations required to calculate the permeability from the test data, ensuring uniformity in reporting. 4. The Importance of "BS EN ISO 22282-2 PDF"
BS EN ISO 22282-2 is a part of a multi-series international standard that focuses on "Geotechnical investigation and testing — Geohydraulic testing." While Part 1 covers general rules, Part 2 focuses on water permeability tests carried out in a borehole without the use of packers. Key Aspects of the Standard
If you are looking for specific guidance on performing the tests, I can provide a breakdown of the (falling head vs. constant head). bs en iso 22282-2 pdf
Under-dewatering an excavation can lead to flooding and instability; over-dewatering can cause ground settlement and damage to neighboring structures. BS EN ISO 22282-2 ensures the data used for dewatering calculations is reliable.
This is the preferred method for depth-specific permeability measurement. A packer system (either single or double) is used to seal off a discrete length of the borehole. The standard defines the equations required to calculate

The primary scope of BS EN ISO 22282-2 is the specification of requirements for water permeability tests performed directly within a borehole that has been drilled into the ground, whether above or below the water table, using what is known as an "open system."
Establish above and below the water table.
