scope:

This standard gives guidance on writing the technical specification for the procurement of lead-acid and nickel-cadmium (alkaline) stationary batteries and chargers for installation in electric power generation plants. The guide covers batteries; chargers, battery accommodation, battery main connections and battery accessories. This equipment usually forms part of either a centralised or unit d.c. supplies system for duties such as switchgear closing/tripping, protection, control, alarm, instrumentation and telecommunication supplies, emergency lighting and emergency drives. The equipment covered by this guide is related to its function rather than design type. Therefore the battery and charger requirements are stated in performance terms rather than being specified by a detailed description of the equipment to be supplied.
