本部分prEN 1504规定了对混凝土表面保护的产品和系统的识别，性能（包括耐久性方面），安全性和一致性的评估要求，以提高混凝土和钢筋混凝土结构的耐久性，以及用于新的混凝土和维修和修理工作。 本标准涵盖的表面防护方法如下: 疏水浸渍; - 浸渍; - 涂层。 EN 13813标准规定了不旨在保护或恢复混凝土结构完整性的建筑物中的地板系统。 当符合本标准的产品和系统用于涉及大量机械负载的地板应用中时，也应满足EN 13813的要求

This Part of prEN 1504 specifies requirements for the identification, performance (including durability aspects), safety and evaluation of conformity of products and systems to be used for surface protection of concrete, to increase the durability of concrete and reinforced concrete structures, as well as for new concrete and for maintenance and repair work. The surface protective methods covered by this standard are the following: - hydrophobic impregnation; - impregnation; - coating. Flooring systems in buildings which are not intended to protect or reinstate the integrity of a concrete structure are standardised in EN 13813. When products and systems complying with this standard are used in flooring applications that involve substantial mechanical loading, they should also satisfy the requirements of EN 13813.
