本标准的目的是提供一种标准程序，用于确定加热系统中使用的带电热能储存装置的能量性能。本标准适用于带电和热放电的蓄热装置。能量可储存为潜热或显热，或两者的组合。本标准不包括与成本、寿命、可靠性有关的因素，也不考虑与特定加热和冷却系统接口的要求。本标准中概述的试验程序和设备最容易适用于用于储存l011 J（108 Btu）或以下热能的装置。

The purpose of this standard is to provide a standard procedure for determining the energy performance of electrically charged thermal energy storage devices used in heating systems.This standard applies to thermal storage devices that are charged electrically and discharged thermally. The energy may be stored as latent heat or as sensible heat or as a combination of the two. This standard does not include factors relating to cost, life, reliability, or the consideration of requirements for interfacing with specific heating and cooling systems. The test procedure and equipment outlined in this standard are most easily adaptable to devices used to store thermal energy on the order of l011 J (108 Btu) or less.
