The values of resistance, also known as N values, are co-related with properties of soil, such as density, bearing capacity etc. This number of blows is termed as penetration resistance of soil and is represented by symbol N. In this split spoon sampler method, a hole 55 to mm in diameter is made in the ground with the help of suitable equipment for conducting the test. The driving energy transferred from the free falling hammer to the driving rod was estimated from the measurements of strain and acceleration below the anvil. The sum of the number of blows required for the second and third 6 in. Static cone penetration test.

The standard penetration resistance offers a gauge of the soil density of soils which are hard to pull up with simply a borehole sampling approach. It provides transparency of those who have inadequate security configurations and policies.

Measurements of driving energy in SPT and various dynamic cone penetration tests - ScienceDirect
TheN-value has been correlated with many other mechanical properties, including shear modulus, unconfined compressive strength, angle of internal friction, and relative density. Also, there are considerable variations in the test throughout the world. Adjust for the energy delivered to the rod by calculating N The consistency of clayey soils can often be estimated from this test. The Standard Penetration test SPT is a common in situ testing method used to determine the geotechnical engineering properties of subsurface soils.

In addition, there are several professional and government certifications that indicate the firm's trustworthiness and conformance to industry best practice. Coupling the standard penetration test with borehole drilling and sampling can be an improvement for understanding certain soil types underground.
