BS 7725-2.2:1994

This standard BS 7725-2.2:1994 Evaluation and routine testing in medical imaging departments. Constancy tests is classified in these ICS categories:

• 11.040.50 Radiographic equipment

This technical report applies to radiographic cassettes and to film changers used to record an X-ray pattern on radiographic film by direct radiography.

This technical report applies to radiographic cassettes and film changers that are equipped with intensifying screen(s).

This technical report does not apply to specialized radiographic cassettes such as mammographic cassettes, multi-section cassettes and cassettes used in dental panoramic tomography. Its application to radiographic cassettes with an integrated anti-scatter grid may not give satisfactory results.

This technical report is a part of a series of Particular Publications (standards and technical reports) which will describe test methods for the constancy of properties of various subsystems of diagnostic x-ray equipment, as described in IEC 1223-1.

Method to check constancy of homogenous contact between intensifying screens and the radiographic film and relative sensitivity of the intensifying screen.
