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).
