本文件描述了循环试验的实验框架、结果和结论，循环试验的目的是根据ISO 18930试验方法建立加速风化与九个室外场地的室外风化之间的相关性。 本循环试验中使用的数字印刷技术类型包括水性喷墨、溶剂喷墨、UV固化喷墨、数字曝光卤化银和热传质。本文件中的图像打印稳定性数据和相关性将被视为此类材料性能的说明。通过适当的实验，验证了将这些相关性推广到其他类别的材料，如染料升华。

This document describes the experimental framework, results, and conclusions from a round robin test that was performed in order to establish correlations between accelerated weathering according to the ISO 18930 test method and outdoor weathering at nine outdoor sites. The types of digital printing technology that were used in this round robin test are aqueous inkjet, solvent inkjet, UV curable inkjet, digitally-exposed silver halide, and thermal mass transfer. The image print stability data and correlations of this document are to be considered illustrative of the performance of these classes of materials. Extension of these correlations to other classes of materials, such as dye sublimation, is verified by appropriate experimentation.
