American Standards — PH22.83-1952, PH22.38-1952 and Z22.33-1941 IN OCTOBER 1952, the American Standards Association approved one new standard, approved revision of a second standard and withdrawal of a third. The new standard, PH22. 83-1 952, Edge Numbering 16mm Motion Picture Film, was published for trial and comment in the January 1951 Journal. Since the change in PH22.38-1952 (formerly 22.38-1944) was so minor, consisting merely of the addition of a note, it was not considered necessary to publish the proposed revision for a trial period. The above two standards are the product of the 1 6mm and 8mm Motion Pictures Committee and are published on the following pages. Approval has been withdrawn from the ASA Recommended Practice, Z22.331941, Nomenclature for Electrical Filters. This recommended practice was initiated by the Motion Picture Research Council as an outgrowth of some work on theater equipment. It was thought at the time that this method of designating electrical filters would be helpful in the motion picture field. It was useful for a while but has not been so for some time; therefore the SMPTE Sound Committee with the approval of the MPRC initiated withdrawal action about a year ago. — H. K. Correction — PH22.80-1950 and PH22.81-1950 AN ERROR has recently been discovered in two American Standards, Scanning Beam Uniformity Test Film for 1 6-Millimeter Motion Picture Sound Reproducers (Laboratory Type), PH22.80-1950 and (Service Type), PH22.81-1950, approved in June 1950 and published in the July 1950 Journal. The sound track width was given as 0.070 inch instead of 0.072 inch. These standards are now being reprinted by ASA and republished here on pages 430 and 431.
