0 引言本国际标准是ISO/R686的修订和补充。本国际标准规定的双画幅和单画幅规格具有相同的纵横比,以使这两种规格幻灯片可由同种原图或复制图制造。为从一系列幻灯片中简化35mm幻灯片的生产,选择了双画幅规格尺寸与ISO1755定义的标准24mm×36mm画面区域的遮幅窗尺寸一致。1 适用的范围和领域1.1 本国际标准规定了35mm双画幅和单画幅规格幻灯片的胶片形式、尺寸、布局和缠绕方向。
0 Introduction This International Standard is a revision and supplement to ISO / R686. The double aspect ratio and single format specifications specified in this International Standard have the same aspect ratio so that both types of slides can be manufactured from the same source or copy. In order to simplify the production of 35mm slides from a series of slides, the choice of double-format size coincides with that of the standard 24mm × 36mm screen area defined by ISO1755. 1 Scope and area of application 1.1 This International Standard specifies the film format, size, layout and winding direction of 35mm dual frame and single frame format slides.
