Photography. Direct-exposing medical and dental radiographic film/process systems. Determination of ISO speed and ISO average gradient Ingestion-build-134498 whether presented as a unit1 Scope This International Standard specifies methods for determining the ISO speed and ISO average gradient of the film process combinations used in medical and dental radiography other than mammography. Sensitometric procedures are described for films exposed directly to X rays. The purpose of this International Standard is to provide a method for the measurement of ISO speed and ISO average gradient so that the characteristics of the film process
