Testing, reliability & durability

The guide discusses various battery systems so that the user can make informed decisions on selection, installation design, installation, maintenance, and testing of stationary standby batteries used in UPS systems.

The standard helps ensure effective fire control, extinguishment, prevention, or exposure protection through requirements for the design, installation, and system acceptance testing of water spray fixed systems for fire protection. It also contains requirements for the periodic testing and maintenance of ultra high-speed water spray fixed systems.

The document outlines the fundamental conditions necessary for the creation of each hazard. It includes identification and characterization of the possible hazards inherent in the application, use, and abuse of Nickel Cadmium cells and batteries. It also includes examples for appliance design which minimizes these hazards. Additionally it presents some typical but non-exhaustive examples of misuse that may precipitate or actions which mitigate the hazard.

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 recommended practice is limited to maintenance, test schedules, and testing procedures that can be used to optimize the life and performance of VRLA batteries for stationary applications. Also provides guidance to determine when batteries should be replaced. The maintenance and testing programs described represent “the best program” based on the information reviewed at the time this document was developed. Stationary cycling applications such as those found in alternative energy applications are beyond the scope of this recommended practice.

The document covers descriptions of products, methods, and procedures relating to stationary batteries, battery electrolyte spill mechanisms, electrolyte containment and control methodologies, and firefighting considerations are provided.

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 standard specifies marking, tests and requirements for sealed nickel cadmium prismatic secondary single cells.
