ISO 10605 covers testing procedures involving electrostatic discharge within road vehicles.
ISO 10605 is accredited by the Technical Committee ISO/TC 22 and Subcommittee SC 3. This test methods needed for electrical disturbances, which is caused by electrostatic discharge, are specified with ISO 10605 requirements. For example, charge build-ups made from movement inside a vehicle or during exiting can result in electrostatic discharge.
Tests that simulate an electrostatic discharge (ESD) into a vehicle electrical system are based on the human ESD model. Sensitive electrical devices can be adversely affected by energy either coupled or radiated from electrostatic discharges. This International Standard describes ESD tests that apply to both automotive electronic modules and vehicles.
ESD Waveforms for ISO 10605
There a four different discharge networks used to accomplish each waveform as required by ISO 10605. The different Resistance and Capacitance values affect the discharge output timing typically measured at 30 and 60ns. When changing networks, the decay time of the waveform changes and results are measured as listed in the table above.
Waveform 1 is the ESD discharge using a 330 pF/330 Ω network
Waveform 2 is the ESD discharge using a 150 pF/330 Ω network
Waveform 1 here is using a 330 pF/2000 Ω discharge network
Waveform 2 here is using a 150 pF/2000Ω discharge network
Starting Profile Waveform of ISO 10605-2
The starting profile waveform is created from from a Load Dump Simulator and a DC Source to simulate an automotive system during start up. This is traditionally seen in Internal Combustion Engine (ICE's) vehicles where cranking occurs upon startup.
