28、 62485 applies to secondary batteries and battery installations used for electric vehicles, e.g. in electric industrial trucks (including lift trucks, tow trucks, cleaning machines, automatic guided vehicles), in battery powered locomotives, in electric vehicles (e.g. goods vehicles, golf carts, bic

29、ycles, wheelchairs), and does not cover the design of such vehicles. This International Standard covers lead dioxide-lead (lead-acid), nickel oxide-cadmium, nickel-oxide-metal hydride and other alkaline secondary batteries. Safety aspects of secondary lithium batteries in such applications will be c

30、overed in their own appropriate standards. The nominal voltages are limited to 1 000 V a.c. and 1 500 V d.c. respectively and the principal measures for protection against hazards generally from electricity, gas emission and electrolyte are described. It provides requirements on safety aspects assoc

31、iated with the installation, use, inspection, maintenance and disposal of batteries. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
