本文件描述了测定彩色摄影图像长期暗存储稳定性的试验方法，以及在特定温度和相对湿度下，当受到特定光源照射时，此类图像的颜色稳定性。 本文件适用于用传统的连续色调照相材料制作的彩色照相图像，以及用染料形成的图像。这些图像由显色、银染料漂白、染料转移和染料扩散转移即时系统生成。这些测试还没有得到验证，以评估用干法生产的彩色图像的稳定性- 以及液体调色剂电子照相、热染料转移（有时称为染料升华）、喷墨、颜料明胶系统、胶印、凹印及相关彩色成像系统。如果这些反射打印材料（包括卤化银（显色）是数字打印的，请参考ISO？18936、ISO？18941、ISO？18946和ISO？18949进行暗稳定性测试，并参考ISO？18937？系列进行光稳定性测试。 本文件不包括图像、支架或粘合剂材料物理稳定性的测试程序。 然而，人们认识到，在某些情况下，诸如支撑脆化、乳液开裂或图像层从其支撑上分层等物理降解，而不是图像稳定性，将决定彩色胶片或打印材料的使用寿命。

This document describes test methods for determining the long-term dark storage stability of colour photographic images and the colour stability of such images when subjected to certain illuminants at specified temperatures and relative humidities. This document is applicable to colour photographic images made with traditional, continuous-tone photographic materials with images formed with dyes. These images are generated with chromogenic, silver dye-bleach, dye transfer, and dye-diffusion-transfer instant systems. The tests have not been verified for evaluating the stability of colour images produced with dry- and liquid-toner electrophotography, thermal dye transfer (sometimes called dye sublimation), ink jet, pigment-gelatin systems, offset lithography, gravure and related colour imaging systems. If these reflection print materials, including silver halide (chromogenic), are digitally printed, refer to ISO 18936, ISO 18941, ISO 18946, and ISO 18949 for dark stability tests, and the ISO 18937 series for light stability tests. This document does not include test procedures for the physical stability of images, supports or binder materials. However, it is recognized that in some instances, physical degradation such as support embrittlement, emulsion cracking or delamination of an image layer from its support, rather than image stability, will determine the useful life of a colour film or print material.
