適用范圍：1.1 This standard prescribes a method of determining certain sensitometric characteristics of developing-out black-and-white photographic papers intended for contact or projection printing of photographic negatives. It specifies the exposing and processing conditions to be used in determining the density-υgrus-log-exposure curve of the photographic papers. It also specifies procedures for deriving numerical values for such significant sensitometric characteristics as speed, maximum shoulder density, density range, and log exposure range.
