The NOL Large Scale Gap Test. III. Compilation of Unclassified Data and Supplementary Information for Interpretation of Results

Abstract

The objectives of this report are to bring up to date the compilations of all unclassified NOL large-scale gap test (LSGT) results, to describe exactly the present standardized test, and to review or report all NOL studies made on the test or modifications of it. The topics presented included standardized test procedure, best test calibration, effect of temperature and porosity on sensitivity, and the effect on test values of modifying the test. A comparison between the NOL large scale and small scale gap test values is given, and also the relationship of the former to the wedge test data. Finally an appendix is devoted to the compilation of critical diameter (dc) measurements and to showing that there is no general relationship between the LSGT results and dc. (Author)
