摄影 缩微胶片、卷轴和轴心 尺寸

[中文适用范围]： 本国际标准规定了用于显微照相应用的原料卷和片状胶片的尺寸（厚度、宽度、长度），包括银明胶、重氮和泡状胶片，设计用于文件记录、计算机输出缩微胶片（COM）和复印或打印。 这些产品在光化辐射成像曝光后需要进行湿化学、蒸汽或热处理； ——卷状薄膜的收卷要求； ——105毫米宽的卷材和片材的标题区域的位置和宽度，以及该区域的背衬的宽度和厚度； ——16毫米、35毫米和105毫米缩微胶片的金属或塑料卷轴尺寸；不包括其他卷轴材料，以及作为缩微胶片记录设备的暗盒、暗盒或盒的组成部分的卷轴； ——宽度为 16 毫米、35 毫米和 105 毫米的塑料和金属芯的尺寸。 通常用于感光复印材料的壁厚为 7.6 毫米或更小的薄壁纸板芯的尺寸不包括在本国际标准中。 本国际标准不适用于显微照相应用中的加工胶片尺寸。 [外文原描述]： This International Standard provides specifications for _ dimensions (thickness, width, length) of raw stock roll and sheet films for micrographic applications, including silver-gelatin, diazo, and vesicular films, designed for document recording, computer output microfilming (COM), and duplicating or printing. These products require wet chemical, vapour, or heat processing after an image-forming exposure with actinic radiation; _ winding requirements for roll films; _ location and width of the heading area for 105 mm wide rolls and sheets, and the width and thickness of the backing of that area; _ dimensions of spools, made either of metal or plastic, for 16 mm, 35 mm, and 105 mm microfilms; other spool materials are excluded, as well as spools that are integral components of cartridges, cassettes or magazines of microfilm-recording equipment; _ dimensions of plastic and metal cores of 16 mm, 35 mm, and 105 mm widths. Dimensions for thin-walled paper-board cores with wall thickness of 7,6 mm or less, used routinely for sensitized duplicating material, are not included in this International Standard. This International Standard is not applicable to processed-film dimensions in micrographic applications.
