In rock coring, the length of core recovered STANDARD PENETRATION TEST NOTES (expressed as percent of the total core run). Zero indicates no sample recovered. The standard penetration test consists of driving the sampler with REV: Revert drilling fluid a 140-pound hammer and counting the number of Mows applied SS: Standard split-spoon sampler (steel; 1%" is inside in each of three 6" increments of penetration. If the sampler is diameter; 2" outside diameter); unless indicated driven less than 18" (usually in highly resistant material), otherwise permitted in ASTM:D 1586, the blows for each complete 6" SU Spin-tip sample from hollow stern auger increment and for each partial increment is on the boring log. TW: Thin-walled tube; number indicates inside diameter For partial increments, the number of blows is shown to the in inches nearest 0.1' below the slash. WASH: Sample of material obtained by screening returning rotary drilling fluid or by which has collected inside The length of sample recovered, as shown on the "REC" the borehole after "falling" through drilling fluid column, may be greater than the distance indicated in the N WH: Sampler advanced by static weight of drill rod and column.The disparity is because the N-value is recorded below 144-pound hammer the initial 6" set (unless partial penetration defined in WR: Sampler advanced by static weight of drill rod ASTM.D1586 is encountered) whereas the length of sample 94mm: 94 millimeter wireline core barrel recovered is for the entire sampler drive (which may even ■ Water level directly measured in boring extend more than 18").
