This standard is issued under the fixed designation F 1072; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. ASTM C 42 describes the testing procedure and explains how the results should be corrected fo r height-to-diameter ratio. The nominal core diameter should not be less than 2 in. (50 mm) with 3 in. (75 mm) being the preferred diameter for shotcrete. ASTM C 823 states when and how cores should be taken, and the required. Test methods (e.g. Acceptance criteria (e.g. ASTM E 186 severity level 2, or MSS SP-54-1995). Any other information that might contribute to the.
