The International Labor Office (ILO) convened a meeting in November 1989 to consider a possible revision of the ILO's International Classification of Radiographs of Pneumoconioses. Among the various suggestions considered was a proposal that sections of some of the standard radiographs that accompany the Classification should be reproduced as quadrants of new standard films. Those new 'QUAD' standards could then replace the full -sized standards involved, thus reducing the total number of full-size (35 x 35 cm) films in the set. It was agreed that the feasibility and possible effects of the proposed change should be studied by means of an appropriately designed film-reading trial. The aim of the trial was to determine whether, and to what extent, the proposed modification to the set of standard radiographs would affect film readers' classifications of chest radiographs of persons with histories of occupational dust exposure.
