标准摘要
[中文适用范围]： 本文件规定了通过高压水射流去除/部分去除水溶性污染物、铁锈、以前的油漆涂层和其他异物后钢材表面的一系列处理等级。 各种等级通过书面描述和照片来定义，这些照片是每个等级在文字描述的公差范围内的代表性示例。 本文件规定了初始表面状况和清洁后闪锈等级，也通过书面描述和代表性照片示例进行定义。 本文件将表面的清洁度应用于其视觉外观。 除了视觉外观之外，还考虑不可见的污染物和粗糙度或轮廓。 ISO 8502 系列中提供了用于测试视觉清洁表面上可溶性盐和其他不可见污染物的物理和化学方法。 表面的粗糙度或轮廓特征可在 ISO 8503 系列中找到。 [外文原描述]： This document specifies a series of preparation grades for steel surfaces after removal/partial removal of water-soluble contaminants, rust, previous paint coatings and other foreign matter by high-pressure water jetting. The various grades are defined by written descriptions together with photographs that are representative examples within the tolerances for each grade as described in words. This document specifies both initial surface conditions and after-cleaning flash rust grades, also defined by written descriptions together with representative photographic examples. This document applies the cleanliness of the surface to its visual appearance. Consideration in addition to visual appearance is given to invisible contaminants and roughness or profile. Physical and chemical methods for testing for soluble salts and other invisible contaminants on the visually clean surface are found in the ISO 8502 series. The roughness or profile characteristics of the surface are found in the ISO 8503 series.
