scope:

This standard is applicable to lead-acid batteries with a nominal voltage of 12 V, used primarily as a power source for the starting of internal combustion engines, lighting and also for auxiliary equipment of internal combustion engine vehicles. These batteries are commonly called "starter batteries". Batteries with a nominal voltage of 6 V are also included within the scope of this standard. All referenced voltages have to be divided by two for 6 V batteries.This standard is applicable to batteries for the following purposes:- batteries for passenger cars,- batteries for commercial and industrial vehicles.This standard is not applicable to batteries for other purposes, for example the starting of railcar internal combustion engines or for motorcycles.NOTE Separate standard for motorcycle batteries is under preparation.
