These automotive pulses occur regularly in the vehicle primarily due to switching on and off of various vehicle components from the starter motor to electrical and electronic systems.
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.
For immunity testing according to
ISO 7627-2, you need a transient generator that includes some kind of coupling network, a battery simulator and function generator. ISO 16750-2 adds a suite of voltage simulations and a load dump test.
Many OEM requirements include ESD testing similar to ISO 10605, for which an NSG 438 or esd NX30 is highly recommended.
