ISO 7637-3 Standard Test for Electrical Disturbances from Road Vehicles, Transmission and Coupling

EUROLAB laboratory provides testing and compliance services within the scope of ISO 7637-3 standard. ISO 7637-3 defines bench testing methods for assessing the immunity of devices under test (DUTs) to transient impulses connected to lines other than supply lines.

ISO 7637-3 Standard Test for Electrical Disturbances from Road Vehicles, Transmission and Coupling

The test pulses simulate both fast and slow transients from switching inductive loads and relay contact bouncing.

The following three test methods are described in ISO 7637-3:

  • Capacitive coupling clamp (CCC) method;
  • Direct capacitive coupling (DCC) method;
  • Inductive coupling clamp (ICC) method.

ISO 7637-3 applies to road vehicles equipped with nominal 12 V or 24 V electrical systems.

It provides recommended test severity levels in accordance with the functional performance state classification (FPSC) principle described in ISO 7637‑1 for transient impulse immunity.
