"The standard applies to the classification of degrees of protection provided by enclosures for electrical equipment with a rated voltage not exceeding 72,5 kV. The object of the standard is to give a) Definitions for degrees of protection provided by enclosures of electrical equipment as regards: 1) protection of persons against access to hazardous parts inside the enclosure; 2) protection of the equipment inside the enclosure against ingress of solid foreign objects; 3) protection of the equipment inside the enclosure against harmful effects due to the ingress of water.

This Part of IEC 62485 specifies the basic requirements for secondary batteries and battery installations. The requirements regarding safety, reliability, life expectancy, mechanical strength, cycle stability, internal resistance, and battery temperature, are determined by various applications, and this, in turn, determines the selection of the battery design and technology. In general, the requirements and definitions are specified for Lead-Acid and Nickel Cadmium batteries. For other battery systems with aqueous electrolyte, the requirements may be applied accordingly.

This part of IEC 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), battery powered locomotives, electric vehicles (e.g., goods vehicles, golf carts, bicycles, wheelchairs) and does not cover the design of such vehicles. The standard covers Lead dioxide-Lead (Lead-Acid), nickel oxide-cadmium, nickel-oxide-metal hydride and other alkaline secondary batteries.

The guidance covers the key elements to consider when devising safe working practices and is for people who carry out work on or near electrical equipment. It includes advice for managers and supervisors who control or influence the design, specification, selection, installation, commissioning, maintenance or operation of electrical equipment.

The document provides recommendations for installation design and for installation, maintenance, and testing procedures to optimize life and performance of vented Nickel Cadmium batteries in stationary standby applications. Also provides guidance for determining when these batteries should be replaced.

The document defines the areas of recommended knowledge for installers and maintainers of stationary batteries and related systems to the extent that they affect the battery. Design of the dc system and sizing of the dc battery charger(s) are beyond the scope of this recommended practice. This document covers Lead-Acid and Nickel Cadmium battery technologies.

Storage equipment and systems connected to an EPS need to meet requirements specified in related IEEE standards. Standardized test procedures are necessary to establish and verify requirement compliance. These test procedures need to provide repeatable results at independent test locations and have flexibility to accommodate the variety of storage technologies and applications. This standard establishes test procedures for electric energy storage equipment and systems for EPS applications.

Covers VRLA batteries, used as a reserve energy source that supports DC-powered telecommunications load equipment. Defines the proper operational use, storage conditions and test criteria initial and lifetime for VRLA cells (modules). Intended to be used to establish initial physical and performance characteristics of VRLA cells or modules, performance expectations throughout their lifetime and operations conditions for appropriate use and guidance for designers of these cells or modules.

The CWA provides guidance on the specification, installation and operation of flow batteries. It facilitates the pre-commercial phase when flow batteries need to be compared with other flow batteries or other electrical storage devices. It provides guidance to conformity assessment bodes to benchmark flow battery conformity with existing directives and other regulations.
