The purpose of this part of ISO 19072 is to define the performance criteria and requirements of a three-way connection interface, including ground connection, linking the pyrotechnic device and harness connector built into a road vehicle.

Performance criteria and requirements are also defined for a sealed variant of the pyrotechnic device/initiator harness connector assembly.

Performance criteria and requirements are also defined for a two-way (without ground) variant of the pyrotechnic device/initiator harness connector assembly.
