[Acceptance test of film processing in roentgen diagnosis].

In radiological acceptance tests, the film processing settings are verified by means of light sensitometry. The preliminary standard DIN 6868-55 probably published in August 1996 standardizes this procedure. This standard, its legal relevance and the sensitometer specifications are discussed. An outlook to the future development of the procedure as regards both the necessary technical progress and the establishment of a hierarchical metrological structure is included.
