1.1 视觉表面处理指南和标准由一系列彩色印刷品组成，可作为单独出版物提供。本标准中描述了五组不同的照片，指定为方法A（ISO/瑞典标准 2. )方法B至E（SSPC指南和参考照片 3. ). 这些方法在初始表面的描述、清洁条件的定义和描述以及包括的清洁方法的数量上有所不同。由于这些差异，说明符应该说明使用哪种指南。 1.2 彩色视觉表面处理指南代表了表面处理前后热轧碳钢的不同条件。 在清洁之前，有四个锈蚀等级，从A到D，涵盖从完整的轧屑到100的范围 % 锈蚀和点蚀钢。然后，标准描述了通过一种或多种方法（例如，干磨料喷砂清理）清洁到不同程度后初始条件的外观。此外，方法B包括三种包含不同程度劣化的涂漆条件。指南 3. 描述了不同程度的干磨料喷砂清理后的这些条件。方法C包括四个锈蚀等级和三种涂漆条件，其中包含不同程度的劣化。指南 4. 描述了不同程度的手动和电动工具清洁后的这些情况。 方法D包括两个锈蚀等级和四种涂漆条件，其中包含不同程度的劣化。指南 5. 描述了不同程度的水喷射后的这些条件，以及三种程度的闪锈。方法E包括两个锈蚀等级。指南 6. 描述了不同程度的湿磨料喷砂清理后的这些情况，包括三个级别的闪锈。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 不同程度的干湿磨料喷砂清理、手动和电动工具清理以及喷水的外观受被清理钢材的初始锈蚀等级和/或现有钢材上涂层的类型和条件的影响。标准和指南有助于目视判断和评估清洁前的锈蚀和/或油漆劣化程度，以及涂漆前钢材表面的清洁程度。 4.2 由于世界各地使用视觉标准和指南的实践以及所采用的表面处理方法的不同，已经形成了五种方法。 在欧洲，视觉标准（方法A）被用作评估清洁程度的主要手段。在美国，SSPC书面定义优先于用作补充的视觉指南和参考照片。方法B、C和D的视觉指南和参考照片符合SSPC书面定义。方法E有书面定义，但是，方法E的视觉指南不包含与每个表面清洁度定义相对应的一整套图片。

1.1 The visual surface preparation guides and standards consist of a series of color prints available as separate publications. Five different sets of photographs are described in this standard, designated as Method A (ISO/Swedish Standard 2 ) and Methods B through E (SSPC Guides and Reference Photographs 3 ). The methods differ in the depiction of the initial surface, in the definition and depiction of the cleaning conditions, and in the number of cleaning methods included. Because of these differences, the specifier should state which guide to use. 1.2 The colored visual surface preparation guides represent different conditions of hot-rolled carbon steel before and after surface preparation. Prior to cleaning, there are four rust grades, A to D, that cover the range from intact mill scale to 100 % rusted and pitted steel. The standards then depict the appearance of the initial conditions after cleaning by one or more methods (for example, dry abrasive blast cleaning) to various degrees of thoroughness. In addition, Method B includes three painted conditions that contain various degrees of deterioration. The Guide 3 depicts these conditions after various degrees of dry abrasive blast cleaning. Method C includes four rust grades and three painted conditions that contain various degrees of deterioration. The Guide 4 depicts these conditions after various degrees of hand and power tool cleaning. Method D includes two rust grades and four painted conditions that contain various degrees of deterioration. The Guide 5 depicts these conditions after various degrees of water jetting, with three levels of flash rusting. Method E includes two rust grades. The Guide 6 depicts these conditions after various degrees of wet abrasive blast cleaning, with three levels of flash rusting. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 The appearance of the various degrees of dry and wet abrasive blast cleaning, hand and power tool cleaning, and water jetting are influenced by the initial rust grades of the steel being cleaned and/or the type and condition of the coating on the existing steel. The standards and guides aid visually in judging and evaluating the degree of rusting and/or paint deterioration before cleaning and the degree of cleaning of steel surfaces prior to painting. 4.2 Five methods have evolved because of differences in the practice of using visual standards and guides throughout the world, and the method of surface preparation employed. In Europe, the visual standards (Method A) are used as the primary means of assessing the degree of cleaning. In the U.S., the SSPC written definitions take precedence with the visual guides and reference photographs used as a supplement. The visual guides and reference photographs of Methods B, C, and D conform to the SSPC written definitions. There are written definitions for Method E, however, the visual guide for Method E does not contain a complete set of pictorials corresponding to each surface cleanliness definition.
