成像材料 照相照片室内光稳定性的测量方法 第 2 部分：氙弧灯曝光

[中文适用范围]： 本文件描述了在特定照度（辐照度）、温度和相对湿度水平下，用以测量照片印刷品在经过滤的氙弧光源下的光稳定性的测试设备和程序。它适用于彩色和单色反射印刷品、透明胶片或半透明胶片。它也适用于一般的照片印刷品、相册或背光显示印刷品。本文描述的一般室内显示条件旨在模拟房屋、公寓和其他居住场所的常见使用条件，在这些情况下，由于过滤（通过窗玻璃）和遮光而产生的间接照明通常是导致显示照片褪色的主要照明。模拟的橱窗显示条件旨在模拟透过标准建筑窗玻璃（双层玻璃）的地面日光。这种显示的典型示例是当图像显示在商店橱窗中，面向户外时，商店外的人可以看到它们[5][6]。注：在某些情况下，物理性能下降（如支撑物脆化、图像层开裂或图像层与支撑物分离）而非图像本身的稳定性将决定印刷材料的使用寿命。ISO 18937-1 中给出了一般指导。 [外文原描述]： This document describes test equipment and procedures for measuring the light stability of photographic prints when subjected to a filtered xenon-arc light source at specified levels of illuminance (irradiance), temperature and relative humidity. It is applicable to both colour and monochrome reflection prints, transparent films, or translucent films. It is also applicable to photographic prints in general, photobooks, or prints for backlit displays. General indoor display conditions described herein are intended to simulate common use conditions found in houses, apartments and other dwelling places where indirect lighting due to filtering (through window glass) and shading is often the principal illumination causing displayed photographs to fade. Simulated in-window display conditions are intended to simulate terrestrial daylight transmitted through standard architectural window glass (double glazing). A typical example of such display can be found when images are displayed in store windows, facing toward the outdoors, so that they can be viewed by people outside of the store [ 5 ][ 6 ] . NOTE It is recognized that in some instances, physical degradation such as support embrittlement, image layer cracking, or delamination of an image layer from its support, rather than the stability of the image itself, will determine the useful life of a print material. General guidance is given in ISO 18937 - 1 .
