DESCRIPTION

BS ISO 9236-3:1999


This standard BS ISO 9236-3:1999 Photography. Sensitometry of screen/film systems for medical radiography is classified in these ICS categories:
  • 37.040.25 Radiographic films
  • 11.040.50 Radiographic equipment

This part of ISO 9236 specifies methods for determination of the sensitometric curve shape, average gradient and speed of a single sample of a screen/film/filmholder/processing system in mammography.

The filmholder may be any means which ensures close screen/film contact and prevents the film from being exposed to ambient light. In particular, the filmholder may be a light-tight vacuum bag, as often used in the laboratory, or a radiographic cassette as used in mammography.

NOTE — Hereafter, screen/film/filmholder combinations will be referred to as "combinations", and will be referred to as "systems" when the processing is included.
