《GB/T 14766-2008摄影 黑白连续影调相纸 ISO感光度和ISO印相范围的测定》由TC102(全国感光材料标准化技术委员会)归口,主管部门为中国石油和化学工业联合会。
本标准等同采用国际标准ISO 6846:1992《摄影――黑白连续影调相纸――ISO 感光度和ISO 印相范围的测定》(英文版),技术内容和编写与ISO 6846:1992保持一致,只是根据我国国家标准的编写要求,删除了ISO 标准的前言,改为我国国家标准的前言。
本标准修订并代替GB/T 14766-1993《黑白相纸感光度和印相范围测定方法》。
本标准规定了黑白相纸ISO感光度和ISO印相范围的测定方法。本标准适用于从黑白底片制作连续影调或艺术摄影的黑白正性反射照片,包括普通卤化银印相纸和放大纸以及可变反差相纸。相纸可用普通药液和设备加工,也可采用催化剂或加热显影的特殊程序。本标准不适用于:a)非银盐相纸;b)高反差银盐相纸,如印刷制版或其它非艺术摄影的相纸;c)直接正像或反转影像的银盐相纸。
本标准在内容上与GB/T 14766-1993相比,主要变化如下:
――修订了前言,增加了引言;
――标准名称更改为“摄影 黑白连续影调相纸 ISO 感光度和ISO印相范围的测定”;
――在第3章中,去掉术语“黑白相纸感光度”、“黑白相纸的印相范围”和“最大净密度”,增加了“最小密度”;
――第4章为新增加的“抽样和贮存”;
――第5章为试验方法,对应于原标准的第4章,但细分了条,增加了评价的内容;
――第6章“产品分类”,对应于原标准第5章,增加了ISO 感光度和ISO 印相范围的精确度的测定;
――第7章“产品标记和标签”,内容对应于原标准第6章,增加了7.3总则;
――增加了附录A、附录B、附录C、附录D。


Scope

This standard specifies the method for measuring the ISO sensitivity and ISO printing range of black and white photographic paper. This standard applies to black-and-white positive reflection prints for continuous-tone or art photography made from black-and-white negatives, including ordinary silver halide printing and enlargement papers, and variable contrast photographic papers. The photographic paper can be processed with common liquid chemicals and equipment, and can also be processed with catalysts or special procedures for heating and developing. This standard does not apply to: a) non-silver photographic paper; b) high-contrast silver photographic paper, such as printing plate or other non-art photographic paper; c) direct positive or reverse image silver salt photographic paper.
