标准范围

1.1本国际标准描述了评价化学转化有效性的方法旨在增加湿处理银图像抗氧化性的处理。治疗可以是作为原始处理的一部分应用，也可以是后处理处理。本国际标准不推荐对银色图像进行一般或特定处理。同样，治疗温度、次数和补充率超出了本国际标准的范围。因素在信息性附件B中讨论了稳定处理中需要考虑的因素。描述了两种测试方法:“重铬酸盐漂白测试”和“过氧化氢孵育测试”（参见[7]在参考书目中）。每种方法的重要性在资料性附件C中讨论。1.2本国际标准适用于涂覆在塑料或纸载体上的银明胶图像或者玻璃。

1.1 This International Standard describes methods for evaluating the effectiveness of chemical conversiontreatments intended to increase the resistance of wet-processed silver images to oxidation. The treatment may beapplied as part of the original processing, or it may be a post-processing treatment.This International Standard does not recommend general or specific treatments for silver images. Likewise,treatment temperature, times and replenishment rates are outside the scope of this International Standard. Factorsto be considered in a stabilizing treatment are discussed in informative annex B.Two test methods are described: the "dichromate bleach test" and the "hydrogen peroxide incubation test" (see [7]in the bibliography). The significance of each is discussed in informative annex C.1.2 This International Standard is applicable to silver-gelatin images coated on supports of either plastic, paperor glass.
