J.Sherman reviewed D2155 and found the the units in the text had already been updated to SI units in accordance with Part H of ASTM Form and Style, specifically H4. Format Requirements for Standards in Inch-Pound Units. It was noted Figures 1 and 2 measurements are in inch-pound units only and Figure 3 in SI units only. J. Sherman could not find in Form and Style sections G and H whether SI units are required in parenthesis for figures ( 1 and 2) as in the text. Further review determined that a mandatory section; Significance and Use, was missing In D2155..
