ISO 7637-1 (last revised October 2015 (2015-10)) Definitions and general considerations
ISO 7637-2 (last revised March 2011 (2011-03)) Electrical transient conduction along supply lines only
ISO 7637-3 (last revised July 2016 (2016-07)) Electrical transient transmission by capacitive and inductive coupling via lines other than supply lines
ISO 7637-4 Electrical transient conduction along shielded high voltage supply lines only
ISO 7637-5 (last revised November 2016 (2016-11)) Enhanced definitions and verification methods for harmonization of pulse generators according to ISO 7637
There are several distinct electrical transient waveforms that are required from this testing to ISO 7637-2. These pulses or waveforms include very high rise or fall times often in the nanosecond and microseconds range. These transients are designed to simulate electrical occurrences in operational environments, including a load dump simulation. ISO 7637 is referenced by many vehicle manufacturer standards and individual waveforms are modified to meet specific requirements. ISO 7637 includes both immunity and emissions components of electromagnetic compatibility testing. This standard, including ISO 7637-2 places specific requirements on test equipment that can be used to replicate electrical occurrences.
