    consistency; handheld shear vane; pocket shear meter; pocket shear vane; pocket vane shear; strength index; Torvane;


    The current Figure 2 Example Schematic of the Torsional Shear Device of ASTM D8121-18 contain excessive details; some of the terms do not agree with those used in paragraphs 6.1 and 6.2 of Section 6, Apparatus; and the current figure does not adequately illustrate the Measuring Scale. The new Figure 2 addresses the above shortcomings and is an original drawing prepared for this Standard; therefore, the figure need not be referenced.
