This International Standard provides test methods and acceptance criteria for the evaluation of the electromagnetic compatibility of construction machinery as defined in ISO 6165 for earth-moving machinery and ISO 8811 for road-construction machines. It deals with General EMC requirements under typical EMC environmental conditions. Functional safety requirements are covered in part 2 of ISO 13766. Electrical and/or electronic component(s) or separate technical unit(s) intended to be fitted in construction machinery are also dealt with in this International 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.
