Soils - Standard Penetration Test (SPT) and Sampling with a Split-Barrel Sampler

National Standard of Canada CAN/BNQ 2501-140 specifies a test method used to determine the penetration index N in vertical drilling and to obtain a disturbed soil sample. The Standard Penetration Test is used during geotechnical investigations for the purpose of determining the nature and compaction of the soil.

This standardized test method establishes the requirements for three specific elements:

• Equipment: drilling equipment, split-barrel sampler, jarring device
• Operating method : preparation of borehole, penetration test, sample extraction
• Drilling report : drilling data, test data
