Annex A Calibration of ionization chambers
Annex B Manual processing with standard chemicals
Specifies methods for determining the ISO speed and average gradient of the film/film-process combinations used in medical and dental radiography other than mammography. Sensitometric procedures are described for films exposed directly to X-rays. Provides a method for the measurement of ISO speed and average gradient so that the characteristics of the film/film-process system can be obtained reproducibly and can also be compared with those of other systems. Standard process formulae and cycles are intended primarily for those applications where specification or comparison work must include a specific published set of formulae and cycle characteristics.
