English: Title: Government discovers method to preserve movie film indefinitely. Washington, D.C., July 8. People living in the year 2000 will be able to see and hear today's history in the making through experiments on preserving movie film now being conducted by the National Bureau of Standards. The experts at the bureau recently completed "accelerated aging tests in which films in six months went through the effects of 50 years' storage in a cool dark room. These tests showed that cellulose, or explosive film, would last from 50 to 100 years. The new Safety or Acetate film "may be preserved for longer periods." Unofficially, the experts put the figure at several hundred years. The following set of pictures were made at the Bureau of Standards and the National Archives Building. (1) Accelerated aging, The stability of the films is tested similarly to paper. They are heated in this oven at 100 [degrees] C and tested for loss of flexibility and for evidences of chemical decomposition. Arnold Soorne, of the Bureau Staff, is picture making the test
