In February 2009, the UK Ministry of Defence published issue 6 of Defence Standard 61-5 part 6 to cover 12 and 24V systems. This issue 6 version has a major change when compared to issue 5 which had been originally published in 1990. The main difference is to define how electrical equipment survives when subjected to the DIT08.B load dump. Load dump occurs when a heavily loaded electrical system exhibits a loose battery terminal, which can be caused by the shock of the military vehicle traversing over rough terrain and the resulting voltage transient presented onto the electrical system by the poor connection defined in the commercial vehicle standard ISO 7637-2.
