ISO 8501-1:2007是四种语言（英语、法语、德语和瑞典语）的精装A5格式书籍，其中规定了一系列钢表面的锈蚀等级和处理等级。各种等级由书面描述和照片定义，这些照片是文字描述的每个等级公差范围内的代表性示例。 本标准适用于通过喷砂清理、手动和电动工具清理以及火焰清理等方法准备涂漆的热轧钢表面，尽管这些方法很少产生类似的结果。基本上，这些方法适用于热轧钢，但特别是喷砂清理方法，也可用于足够厚度的冷轧钢，以承受磨料冲击或电动工具清理效果造成的任何变形。 ISO 8501的本部分也适用于除残余氧化皮外，还残留有牢固附着的油漆和其他异物的钢基材。

ISO 8501-1:2007 is a hardback A5-format book in four languages (English, French, German and Swedish), which specifies a series of rust grades and preparation grades of steel surfaces. The various grades are defined by written descriptions together with photographs that are representative examples within the tolerance for each grade as described in words. It is applicable to hot-rolled steel surfaces prepared for painting by methods such as blast-cleaning, hand and power tool cleaning and flame cleaning, although these methods rarely lead to comparable results. Essentially, these methods are intended for hot-rolled steel, but blast-cleaning methods, in particular, could also be used on cold-rolled steel of sufficient thickness to withstand any deformation caused by the impact of the abrasive or the effects of power tool cleaning. This part of ISO 8501 is applicable also to steel substrates that show residues of firmly adhering paint and other foreign matter in addition to residual mill scale.
