This standard BS AU 265-2:1995 Road vehicles. Ignition systems is classified in these ICS categories:
- 43.060.50 Electrical and electronic equipment. Control systems
This part of ISO 6518 specifies the methods and test conditions for testing battery-supplied ignition systems for spark-ignited internal combustion engines.
Because of the difficulties in producing repeatable measurements with atmospheric spark gaps and different observers, two methods of obtaining the results necessary for calculating the system output energy are given.
Method A — using spark gaps for the energy measurement (test arrangement A). The output energy obtained by this method is called spark energy, Esp.
Method B — using a Zener diode string for the energy measurement (test arrangement B). The output energy obtained by this method is called Zener discharge energy, Ezd.
This method is not suitable for systems giving alternating spark current.
Method B is also recommended for the comparative testing of ignition coils and current interruption systems.
