scope:

This standard is applicable to lead-acid batteries with a nominal voltage of 12V, 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 6V are also included within the scope of this standard. All referenced voltages have to be divided by two for 6 batteries. This standard is applicable to batteries for the following purposes: - batteries for passenger cars; - batteries for commercial and industrial vehicles for normal use; - batteries for commercial and industrial vehicles for severe use. This standard is not applicable to batteries for other purposes, for example the staring of railcar internal combustion engines. The object of this standard is to specify: - general requirements; - certain essential functional characteristics, the relevant test methods and results required, for several classes of starter batteries.
