The paper which provides additional information about the statistical attributes of the pin penetration, reviews the background of the methods for estimating the in-place strength of concrete, and describes the experimental program and results. It was found that for the range of penetration values considered, the within-test variability is described by a constant standard deviation having an average value of about 0.015 in. On the average about one fourth of the test results conducted on 4 by 8-in. cylinders were outliers because of penetrations into coarse aggregate particles or large air voids. These and other study findings are discussed.
