标准摘要
[中文适用范围]： 本文件规定了评估涂有油漆和清漆（有机涂层）以及金属涂层加有机涂层（双层系统）的涂覆表面生锈程度的方法。通过将涂覆表面与图解标准进行比较来评估生锈程度。 本文件提供的图解标准展示了由于锈蚀穿透涂层并在底材下可见的不同严重程度的损坏的表面。本文件中对生锈程度的评估只是涂层面受损面积的一种估计，边缘不计入。 [外文原描述]： This document specifies methods for assessing the degree of rusting of surfaces coated with paints and varnishes (organic coatings), and metallic coating plus an organic coating (duplex system), by comparison with pictorial standards. The pictorial standards provided in this document show surfaces which have deteriorated to different degrees by a combination of rust broken through the coating and visible under-rusting. The assessment of the degree of rusting in this document is only an estimation of the affected area on specimen. Edges are not included.
