ISO 7637 Road vehicles -- Electrical disturbances from conduction and coupling[1] is an international electromagnetic compatibility vehicle standard published by the International Organization for Standardization (ISO), that relates to 12- and 24-volt electrical systems.
These pulses or waveforms include very high rise or fall times often in the nanosecond and microseconds range.
ISO 7637 is referenced by many vehicle manufacturer standards and individual waveforms are modified to meet specific requirements.
[8] ISO 7637 includes both immunity and emissions components of electromagnetic compatibility testing.
[9] This standard, including ISO 7637-2 places specific requirements on test equipment that can be used to replicate electrical occurrences.
