Popis
BS ISO 5799:1991
This standard BS ISO 5799:1991 Photography. Direct-exposing medical and dental radiographic film/process systems. Determination of ISO speed and ISO average gradient is classified in these ICS categories:
- 37.040.25 Radiographic films
- 11.040.50 Radiographic equipment
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 system can be obtained reproducibly and can also be compared with those of other systems.
