铝及铝合金阳极氧化 用人造光加速试验彩色阳极氧化涂层的耐光性

[中文适用范围]： 本文件规定了一种使用人造光评估铝及其合金彩色阳极氧化涂层牢度的加速试验方法。为了评估室外暴露下的耐光性，只有在与实际使用条件相当的户外暴露条件下才能完全令人满意。加速试验适合作为彩色阳极氧化涂层的质量控制试验，这些涂层的耐光性数值已经通过户外暴露试验确定。该方法适用于以任何方式和为任何目的生产的铝及其合金彩色阳极氧化涂层。但是，该方法不适用于测量已经通过户外暴露试验确定耐光性数值小于 6 的彩色涂层。户外暴露试验在 ISO 105-B01 中进行了描述。 [外文原描述]： This document specifies an accelerated test method for assessing the fastness, using artificial light, of coloured anodic oxidation coatings on aluminium and its alloys. For evaluating light fastness on exterior exposure, only outdoor exposure under conditions comparable with actual service is completely satisfactory. Accelerated testing is suitable as a quality-control test of coloured anodic oxidation coatings whose light fastness number has already been established by means of outdoor exposure testing. The method is applicable to coloured anodic oxidation coatings on aluminium and its alloys produced by any means and for any purpose. However, the method is not suitable for the measurement of coloured coatings with a light fastness number already established by means of outdoor exposure testing and of less than 6. The outdoor exposure test is described in ISO 105 - B01 .
