本文件规定了在涂覆油漆和相关产品之前，钢材表面处理的喷砂清理方法。它提供了有关各个方法及其应用领域的有效性的信息。它描述了要使用的设备和要遵循的程序。 注:这些方法主要用于热轧钢，以去除轧屑、锈迹等，但也可用于足够厚度的冷轧钢，以承受磨料冲击造成的变形。

This document specifies abrasive blast-cleaning methods for the preparation of steel surfaces before coating with paints and related products. It provides information on the effectiveness of the individual methods and their fields of application. It describes the equipment to use and the procedure to follow. NOTE These methods are essentially intended for hot-rolled steel to remove mill scale, rust, etc. but could also be used for cold-rolled steel of sufficient thickness to withstand the deformation caused by the impact of abrasive.
