BS EN ISO 22282-5:2012 PDF Download

BS EN ISO 22282-5:2012 is a standard that establishes requirements for ground investigations using infiltrometer tests as part of geotechnical investigation services. It applies to determining the water permeability of existing geological formations or treated/compacted materials. The infiltrometer test is used to determine the infiltration capacity of the ground at the surface or shallow depth, allowing for the measurement of the permeability coefficient. The test can be conducted under different conditions, such as steady-state or transient, and can be applied to saturated or unsaturated soils.

The standard defines the terminology and parameters, as well as the required characteristics of the equipment. It also specifies the procedures and measurement techniques for the tests, along with the interpretation of the results. The test can be conducted using different types of infiltrometer designs, such as single and double-ring designs, both open and closed. The duration of the test can vary depending on environmental conditions and soil permeability, ranging from a few minutes to a few days.

BS EN ISO 22282-5:2012 has applications in various areas including civil engineering projects, hydrogeology studies, and waste storage. This standard is part of a series of standards on geotechnical investigation and testing, with other parts covering general rules, water permeability tests using open or closed systems, water pressure tests in rock, and pumping tests.
