: An instantaneous change in the water level (head) is induced—either by adding water (falling head) or removing it (rising head)—and the rate at which the level returns to its original state is recorded. Constant Head Method :

The standard is a critical document for civil engineers, hydrogeologists, and geotechnical contractors. It defines the requirements and procedures for determining the local water permeability of soil and rock using open systems within a borehole . Unlike closed systems that use packers to isolate sections under pressure, open systems typically involve measurements where the water surface is open to atmospheric pressure. Scope and Purpose of the Standard bs en iso 22282-2 pdf

A standard-compliant investigation requires two distinct reports: : An instantaneous change in the water level

: Devices used to measure the rate of injection or withdrawal must be accurate to within 5% of the reading range .
