1 Scope
This Standard provides test methods and acceptance criteria for the evaluation of the electromagnetic compatibility of earth-moving machinery as defined in GB/T 8498. The following electromagnetic phenomena are evaluated:
– broadband and narrowband electromagnetic interference;
– electromagnetic field immunity test;
– broadband and narrowband interference of electrical/electronic subassemblies;
– electromagnetic field immunity test of electrical/electronic subassemblies;
– electrostatic discharge;
– conducted transients.
