Scope

NB/T 20028.4-2010 is the English-translated version of 核电厂用蓄电池第4部分：维护、试验和更换方法.

NB/T 20028.4-2010 is the Chinese standard "The Batteries Used in Nuclear Power Plants - Part 4: Recommended Practice for Maintenance, Testing and Replacement".

Its scope clause reads: This part specifies the maintenance, test schedule and test methods of stationary batteries (including lead-acid batteries and nickel-cadmium batteries, hereinafter referred to as batteries except for special reference) used in nuclear power plants, and gives time guidelines for determining when to replace batteries.

This part is applicable to the maintenance, testing and replacement of stationary batteries used in nuclear power plants. This part is neither applicable to other types of batteries and their applications, nor to batteries used in some special applications (e.g. emergency lighting devices and movable equipment, etc.).

This part does not include supervision and testing of any other components of the DC system (battery is a part of the DC system) or the DC system itself. Its clauses include terms and definitions.

3 Terms and definitions

For the purposes of this document, the terms and definitions established in NB/T 20028.1 and NB/T 20028.2-2010 as well as the following apply.

3.1 acceptance test

a constant-current or constant-power capacity test made on a new battery to determine that 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 terminal voltage

3.3 performance test

a constant current or constant power capacity test, made on a battery after it has been in service, to detect any change in the capacity

3.4 modified performance test

a test, in the "as found" condition, of a battery's capacity and its ability to satisfy the battery duty cycle

3.5 service test

a test, in the actual condition, of a battery's capacity to satisfy the battery duty cycle […]
