Scope: This standard specifies the method for measuring the ISO sensitivity and ISO printing range of black and white photographic paper. This standard applies to black-and-white positive reflection prints for continuous-tone or art photography made from black-and-white negatives, including ordinary silver halide printing and enlargement papers, and variable contrast photographic papers. The photographic paper can be processed with common liquid chemicals and equipment, and can also be processed with catalysts or special procedures for heating and developing. This standard does not apply to: a) non-silver photographic paper; b) high-contrast silver photographic paper, such as printing plate or other non-art photographic paper; c) direct positive or reverse image silver salt photographic paper.
