A—specified by the agency.
n/a—not applicable.
TOC—time of construction.
PI—profile index.

¹Target AQC means and standard deviations are specific to the chosen sampling and testing methods. Appropriate mean and standard deviation values shall be chosen in accordance with the guidelines set forth in chapter 4 of this volume.

²The required number of AQC samples per sublot shall be chosen by the agency in accordance with the guidelines set forth in chapter 5 of this volume.
