Automotive Electrical Disturbances

These automotive electrical disturbances occur regularly in the vehicle primarily due to switching of various vehicle components and affected by the vehicle harness and other parallel loads. There are both emissions and immunity tests required by the standards, of which there are many. The main standards like ISO 7637-2 and ISO 16750-2 define both how these pulses must be simulated and how they are measured and with what limits. The vehicle manufacturers, who are ultimately responsible, often take these requirements and expand or modify them.

  • Transient Immunity

    Systems for the testing of immunity of electronic and electrical subassemblies against transients that occur in vehicles, conducted on both battery and signal/data lines as defined in ISO 7637-2 and ISO 7637-3, ISO 16750-2, ECE Reg. 10 and many OEM specifications.
