The description of the requirements for interferences by radiation is performed in compliance with [DIN 40 839-4;DIN 40 839-4;;all;]. It includes requirements and tests in order to guarantee electromagnetic compatibility (EMC) of electronic components with respect to interferences which can couple into power supply conductions and signal conductions and/or into electronic vehicle units.
The a.m. standard describes the measurement of electromagnetic fields, the test set-up; furthermore it gives advice concerning limit values (frequency range and field strength).
