This standard specifies the measurement methods for the ISO sensitivity and ISO printing range of black-and-white photographic paper. This standard applies to black-and-white positive reflective photos made from black-and-white negatives for continuous tonal effects or artistic photography, including ordinary silver halide printing paper, enlargement paper, and variable contrast printing paper. The photographic paper can be processed with ordinary developer and equipment, or with special procedures such as catalyst or heat development.
