STANDARD PENETRATION TEST
The number of blows required to drive the sampler three six-inch increments are recorded
on the boring logs. The first six inches is considered the seating drive. The summation of the
number of blows required for the second and third six inches is termed the penetration resistance
"N" value in blows per foot (bpf). This field procedure is referred to as the Standard Penetration
Test (SPT) and is an American Society for Testing and Materials test procedure (ASTM
D-1586).
