IEEE 1106-2005 pdf download IEEE Recommended Practice for Installation, Maintenance, Testing, and Replacement of Vented Nickel-Cadmium Batteries for Stationary Applications
1.Overview
1.1 Scope
This recommended practice is applicable to all stationary standby applications. However, specificapplications,such as emergency lighting units and semiportable equipment,may have other appropriatepractices and are beyond the scope of this recommended practice. Stationary cycling applications, such asthose found in alternative energy applications, are also beyond the scope of this documment.
Sizing, qualification, and other battery types are beyond the scope of this recommended practice.
This recommended practice does not include any other component of the dc system, nor does it includeinspection and testing of the overall dc system. Preoperational and periodic dc system tests of chargers andother dc components may require that the battery be connected to the system. Details for these tests wildepend on the requirements of the dc system and are beyond the scope of this recommended practice.
1.2 Purpose
This recommended practice provides recommendations for installation design and for installationmaintenance, and testing procedures that can be used to optimize the life and performance of vented nickelcadmium batteries used in stationary standby applications. This recommended practice also providesguidance for determining when these batteries should be replaced.
2. Normative references
The following referenced documents are indispensable for the application of this recommended practice. Fordated references, only the edition cited applies. For undated references, the latest edition of the referenceddocument (including any amendments or corrigenda) applies.
IEEE Std 1115TM,IEEE Recommended Practice for Sizing Nickel-Cadmium Batteries for StationaryApplications.
3. Definitions
For the purposes of this recommended practice, the following terms and definitions apply. The AuthoritativeDictionary oflEEE Standards Terms (B2] should be referenced for terms not defined in this clause.
3.1 acceptance test: A constant-current or constant-power capacity test made on a new battery to determinethat it meets specifications or manufacturer’s ratings.
3.2 capacity test: A discharge of a battery at a constant current or constant power to a specified terminalvoltage.
3.3 float charge: A constant potential normally applied to a battery to maintain it in a charged condition.
3.4 high-rate charge: The application of a constant-potential charge, at a higher level than the float chargc,to a partially or fully discharged battery to recharge it.
3.5 performance test: A constant-current or constant-power capacity test, made on a battery after being inservice, to detect any change in the capacity.
3.6 service test: A special test of a battery’s capability, in an “as found” condition, to satisfy the battery dutycycle.
3.7 standby operation (battery): Operation with a battery charger serving to maintain a battery in acharged condition and to supply the normal dc load, Syn: continuous-float operation.
