本欧洲标准规定了结构和性能要求，以及紧密联接的套件，一体式和独立的WC平底锅的测试方法，其具有用于由釉面陶瓷或不锈钢制成的个人卫生的整体陷阱。 本欧洲标准不适用于蹲便器，没有集成式疏水阀的WC平底锅或冲水池作为单独的设备。 在独立的WC锅的情况下，相关的冲水池和压力阀由其他标准覆盖，本标准中对水箱的参考仅与冲洗量的定义和要求有关。 在紧耦合套件和单件WC的情况下，本标准还规定了具有冲洗机构，入口阀和溢流器的指定冲洗水箱的设计，性能要求和测试方法。对于这些产品，本标准涵盖设计用于连接到建筑物内的饮用水设施的冲洗水箱。 在安装WC之前，需要考虑EN 12056-2和国家要求

This European Standard specifies constructional and performance requirements together with test methods for close-coupled suites, one-piece and independent WC pans with integral trap used for personal hygiene manufactured from glazed ceramics or stainless steel. This European Standard does not apply to squatting toilets, WC pans without integral trap or flushing cisterns as separate appliances. In the case of independent WC pans, the associated flushing cisterns and pressure valves are covered by other standards and the reference to cisterns in this standard is related only to the definition and requirements of flushing volume. In the case of close-coupled suites and one-piece WCs, this standard also specifies design, performance requirements and the test methods for designated flushing cisterns with flushing mechanisms, inlet valves and overflows. For these products, this standard covers flushing cisterns designed to be connected to drinking water installations inside buildings. Before installation of WCs, EN 12056-2 and national requirements need to be taken into consideration.
