Abstract
Evaluation of film quality is often based upon the film's characteristic curve. A practical test method implying radiography of sandpaper sheets has been devised, yielding crucial information about the quality, which cannot be derived from the characteristic curve. Since this test appears to give more valid information about film quality than conventional sensitometry, it is suggested that the test procedure should be standardised and used by the manufacturers.Keywords
