1.1本规程包括在涂覆涂料之前清洁混凝土表面，以清除油脂、污垢和松散材料。程序包括扫帚清洁、真空清洁、鼓风清洁、水清洁、洗涤剂水清洁和蒸汽清洁。 1.2本规程的目的不是改变混凝土的表面轮廓，而是清洁表面。 1.3以英寸-磅为单位的数值应视为标准值。本标准不包括其他计量单位。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 有关具体的危险说明，请参阅第5节。 ====意义和用途====== 表面清洁用于制备混凝土表面，以便涂覆用于轻型服务的涂层。 如果保护系统将用于连续或间歇浸入、机械加载，或用于需要最佳粘合以获得满意性能的保护系统，则不打算单独使用本规程（见规程 D4259 和 D4260 ).

1.1 This practice includes surface cleaning of concrete to remove grease, dirt, and loose material prior to the application of coatings. Procedures include broom cleaning, vacuum cleaning, air blast cleaning, water cleaning, detergent water cleaning, and steam cleaning. 1.2 This practice is not intended to alter the surface profile of the concrete but to clean the surface. 1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 5. ====== Significance And Use ====== Surface cleaning is used to prepare concrete surfaces for applying coatings intended for light-duty service. Use of this practice alone is not intended where protective systems will be used for continuous or intermittent immersion, mechanical loading, or for protective systems needing optimum bond for satisfactory performance (see Practices D4259 and D4260 ).
