What is ISO 22282-5- Geohydraulic testing by infiltrometer tests about?
ISO 22282 is an international standard that discusses geotechnical investigation and testing.
ISO 22282-5 is the fifth part of the series that establishes requirements for ground investigations by means of infiltrometer tests as part of geotechnical investigation services in accordance with EN 1997-1 and EN 1997-2.
ISO 22282-5 applies to the in-situ determination of the water permeability of an existing geological formation or of treated or compacted materials.
ISO 22282-5 is applicable to:
- Civil engineering projects
- Hydrogeology studies
- Waste storage
Who is ISO 22282-5- Geohydraulic testing by infiltrometer tests for?
ISO 22282-5 on geohydraulic testing is useful for:
- Geotechnical investigation and testing
- Geotechnical contractors and consultants
- Hydrogeologists
- Civil engineers
- Geotechnical engineers
Why should you use ISO 22282-5- Geohydraulic testing by infiltrometer tests?
Geotechnical testing is carried out by geotechnical engineers, geotechnical technicians, or engineering geologists to determine the features of a worksite, such as the physical attributes.
ISO 22282-5 defines the terminology and the measured parameters. It specifies the required characteristics of the equipment, defines the procedures of the tests relating to the different measurement techniques, and specifies the results of the test.
The infiltrometer test is used to determine the infiltration capacity of the ground at the surface or shallow depth. It is a simple test for determining the permeability coefficient. The method can be applied using either steady-state or transient conditions, in saturated or unsaturated soils.
The principle of the test is based on the measurement of a surface vertical flow rate of water that infiltrates the soil under the influence of a positive hydraulic head.
Infiltrometer testing as part of a geotechnical investigation and testing in accordance with ISO 22282-5 can provide indications on the subsurface site conditions, that is critical from the point of view of stormwater management and mitigation. Understanding how the soil will react to large inflow of water is critical to ensure the integrity of your civil engineering works.
