Abstract: Test methods for the evaluation OJ motion-picture film for permanent records require test specimens too large to be removed from certain archival films. To assist those charged with the preservation of such 3lms in determining the quality und checking the condition of them, suitable semimicro methods were developed for acidity, viscosity, and residual hypo content. Specimens as small as 7 mg. in weight, removed from the film with a small hand punch, gave satisfactory resu1ts for the purpose.
