July, 1945 WORK OF ASA WAR COMMITTEE 37
of light output, or the peak light output, which so many lamp users have attempted to use as a guide in rating lamps in the past.
Other still photographic standards adopted included one for 35mm slide films which are also used extensively for training and instructional purposes and another for testing the resolution of slidefilm projector lenses. Proposed standards for still contact printers and for slide-film projectors are in the final stages of approval. In addition much work has been done on standard test methods for both between-the-lens and focal-plane shutters and on the standardization of shutter markings.
As you may judge from the above brief report, the amount of detail involved in conducting the work of the War Committee has been quite extensive. All in all, 191 drafts alone have been circulated to the War Committee and its subcommittees on the 71 projects which have either been approved or reached a satisfactory stage to merit assignment of an identification number.
The part the Society and its officers played in the work of the War Committee has been a large one and without their cooperation much of this work could never have been accomplished. The Research Council of the Academy has been extremely helpful, particularly with regard to the standards for 35-mm motion pictures, since it has helped us to a very great extent by assuming the secretarial burden for three of the subcommittees which have been active.
In conclusion, I should like to say that copies of the various American War Standards, which have been approved, may be obtained from the American Standards Association's offices in New York by those who have not already done so. Copies of the various draft standards, which are under consideration, will be gladly furnished, without charge, to anyone who is interested.
