1.1本欧洲标准规定了安全要求 - 输送机， - 喷涂机， - 放置机器，和 - 送货线系统 对于3.3至3.6中定义的混凝土和砂浆。 机械可以是静止的或移动的。 本欧洲标准不包括: - 在运输，喷涂和放置时可移动的机器; - 本标准涵盖的任何机器的舱室; - 超出输送，喷涂和放置混凝土和砂浆的附加功能，例如独立混合功能或起重机功能; - 隧道运行要求; - 不是专门设计用于混凝土分配吊杆的支撑结构（即塔架系统）。 本欧洲标准未规定特殊规定的操作的附加要求（例如潜在的爆炸性环境，电力网络供电，电压，频率和公差不同于公共供电，地震，闪电，公共道路等使用的电气网络。 ）。 1.2本欧洲标准涉及所有重大危险，危险情况和与输送，喷涂和放置机器相关的事件，如果按照预期使用，并且在制造商合理预见的误用条件下（见Cla

1.1 This European Standard specifies the safety requirements for - conveying machines, - spraying machines, - placing machines, and - delivery line systems for concrete and mortar as defined in the definitions in 3.3 to 3.6. The machinery can be stationary or mobile. This European Standard does not cover: - machines that are mobile during conveying, spraying and placing; - cabins for any machines covered by this standard; - additional functions beyond conveying, spraying and placing concrete and mortar, e.g. separate mixing function or crane function; - requirements for operation in tunnels; - support structures (i.e. tower systems) not exclusively designed for the use with concrete distribution booms. This European Standard does not establish the additional requirements for operations subject to special rules (e.g. potentially explosive atmospheres, supply by electrical networks where voltage, frequency and tolerance differ from those of the public supply, earthquake, lightning, using on public roads, etc.). 1.2 This European Standard deals with all significant hazards, hazardous situations and events relevant to conveying, spraying and placing machines when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards during transportation, assembly, dismantling, disabling, scrapping, operation and maintenance. 1.3 This European Standard is not applicable to machines which are manufactured before the date of publication of this document by CEN.
