The Standard Penetration test (SPT) is one sort of in-situ soil test and it's far carried out to decide the geotechnical engineering homes of subsurface soils, especially for cohesionless soil.

SPT Test is most widely used to check diverse parameters and houses of soil on the development website online. For any constructing basis, design and production soil testing are important.

The test is extremely useful for figuring out the bearing ability, density, and attitude of shearing resistance of any soil. it may be used to determine the homes of cohesive and cohesionless soil. the same old Penetration check ASTM e1105
