2. Oedometer test - Wikipedia

   en.wikipedia.org/wiki/Oedometer_test

   The soil sample in an oedometer test is typically a circular disc of diameter-to-height ratio of about 3:1. The sample is held in a rigid confining ring, which prevents lateral displacement of the soil sample, but allows the sample to swell or compress vertically in response to changes in applied load.

3. Standard penetration test - Wikipedia

   en.wikipedia.org/wiki/Standard_penetration_test

   The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide. The test procedure is described in ISO 22476-3, ASTM D1586 [1] and Australian Standards AS ...

4. Soil test - Wikipedia

   en.wikipedia.org/wiki/Soil_test

   In geotechnical engineering, a soil test can be used to determine the physical characteristics of a soil, such as its water content, void ratio or bulk density. Soil testing can also provide information related to the shear strength, rate of consolidation and permeability of the soil. The following is a non-exhaustive list of engineering soil ...

5. Plasma osmolality - Wikipedia

   en.wikipedia.org/wiki/Plasma_Osmolality

   Calculated osmolarity = 2 Na + Glucose + Urea (all in mmol/L) As Na+ is the major extracellular cation, the sum of osmolarity of all other anions can be assumed to be equal to natremia, hence [Na+]x2 ≈ [Na+] + [anions] To calculate plasma osmolality use the following equation (typical in the US): = 2[Na +

6. Base-cation saturation ratio - Wikipedia

   en.wikipedia.org/wiki/Base-cation_saturation_ratio

   Base-cation saturation ratio (BCSR) is a method of interpreting soil test results that is widely used in sustainable agriculture, supported by the National Sustainable Agriculture Information Service (ATTRA) [1] and claimed to be successfully in use on over a million acres (4,000 km 2) of farmland worldwide.

7. Percolation test - Wikipedia

   en.wikipedia.org/wiki/Percolation_test

   A percolation test (colloquially called a perc test) is a test to determine the water absorption rate of soil (that is, its capacity for percolation) in preparation for the building of a septic drain field (leach field) or infiltration basin. [1] The results of a percolation test are required to design a septic system properly.

   Tom Holland is set to film Christopher Nolan’s new movie in 2025 alongside Matt Damon, Anne Hathaway, Zendaya, Charlize Theron and more. But the “Spider-Man” actor remains mostly out of the ...

9. Cone penetration test - Wikipedia

   en.wikipedia.org/wiki/Cone_penetration_test

   The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils. Based on this history it has also been called the "Dutch ...
