Construction machinery - Electromagnetic compatibility of machines with internal power supply

This European Standard provides test methods and acceptance criteria for the evaluation of the electromagnetic compatibility of construction machinery with respect to free trade of goods in the European Union. It deals with functional EMC requirements under typical EMC environmental conditions. This European Standard does not deal with safety requirements. Electrical and/or electronic component(s) or separate technical unit(s) intended to be fitted in construction machinery are also dealt with in this European Standard. The following electromagnetic disturbance phenomena are evaluated: - broadband and narrowband electromagnetic interference; - electromagnetic field immunity test; - broadband and narrowband interference of electrical/electronic sub-assemblies; - electromagnetic field immunity test of electrical/electronic sub-assemblies; - electrostatic discharge; - conducted transients. Construction machinery can have DC and/or AC internal electrical power supply systems. Machines that are designed to be supplied by the "Public Mains Network" are specifically excluded.
