While BS EN ISO 22282‑2 deals with open‑system borehole tests, it is often mentioned alongside BS EN ISO 22282‑3, which covers water pressure tests in rock, commonly known as Lugeon tests. The Lugeon test is a variant of the water pressure test widely used in rock engineering. Permeability is expressed in (Lu), where one Lugeon equals one litre of water taken per metre of test length per minute at a pressure of 10 bars. bs en iso 22282-2 pdf

The introduction of the BS EN ISO 22282 series marked a major change in UK geotechnical practice. It replaced the testing methods that had previously been covered by the withdrawn British Standard BS 5930. The publication was described by the BSI director of publishing as “critical to the geotechnical industry” because the relevant testing sections of BS 5930 have now been formally withdrawn.
