Commissioning

Jan 2005 - Administratively Withdrawn Safety precautions;
The document provides safety precautions, installation design considerations, and procedures for receiving, storing, commissioning, and maintaining pocket- and fiber-plate Nickel Cadmium storage batteries for PV power systems. Disposal and recycling recommendations are also discussed. This recommended practice applies to all PV power systems, regardless of size or application that contain Nickel Cadmium battery storage subsystems.

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.

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 standard establishes minimum requirements for the application of the process of commissioning buildings and systems, and criteria for code officials (authority having jurisdiction [AHJ]), owners, and agencies to implement the commissioning requirements.

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.

The standard specifies marking, designation, dimensions, tests and requirements for vented Nickel Cadmium prismatic secondary single cells.

This international standard provides general information about secondary batteries used in PVES and the typical methods of test used for the verification of battery performance. This standard does not include specific information relating to battery sizing, method of charge or PVES design. NOTE: This standard is applicable to Lead-Acid and Nickel Cadmium cells and batteries. This standard will be amended to include other electrochemical systems when they become available.

Specifies marking, designation, dimensions, tests and performance requirements for portable sealed Nickel Cadmium small prismatic, cylindrical and button rechargeable single cells, suitable for use in any orientation.
