Construction machinery - Electromagnetic compatibility of machines with internal electrical power supply

This European Standard provides test methods and acceptance criteria for the evaluation of the electromagnetic compatibility of construction machinery. Electrical and/or electronic component(s) or separate technical unit(s) intended to be fitted in con-struction machinery are also dealt with in this European Standard, except regarding immunity for those parts whose functions are not involved in the direct control and/or modification of the state functions of the machine. 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 may 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.
