1. The Standard Penetration test (SPT) is a common in situ testing method used to determine the geotechnical engineering properties of subsurface soils. It is a simple and inexpensive test to estimate the relative density of soils and approximate shear strength parameters.

2.SPT equipment includes:
1.SPTammer set 63.5kg/140lb
2. SPT sampler
3. Split tube sampler
4.Hammer hanger

5. SPT Nose cone
6. Inner guide shaft

3. Features
Easy operation,convenient to use
Can work with drilling rig directly
Applied in clayey soil, sandy soil,wide application
clayey soil, sandy soil

4.Standard Penetration Test Prcess
SPT, involves driving a standard thick-walled sample tube into the ground at the bottom of a borehole by blows from a slide hammer with standard weight and falling distance. The sample tube is driven 150 mm into the ground and then the number of blows needed for the tube to penetrate each 150 mm (6 in) up to a depth of 450 mm (18 in) is recorded. The sum of the number of blows required for the second and third 6 in. of penetration is reported as SPT blowcount value, commonly termed "standard penetration resistance" or the "N-value".
