BS EN 12977-3:2018规定了用于EN 12977-1:2018规定的小型定制系统的存储性能表征的测试方法。根据本文件测试的存储通常用于太阳能加热系统。但是，也可根据本文件规定的试验方法，评估以水为储存介质的所有其他热贮存器的热性能。本文件适用于标称容积在50 l至3000 l之间的仓库。本文件不适用于梳状晶体管。EN 12977-4:2018中规定了太阳能组合晶体管的性能测试方法。交叉引用:EN 12897ISO 9459-5EN 12828EN ISO 9488（采用ISO 9488:1999）EN 12976-2EN 12897EN 15332EN 12977-2:2018EN 12977-4:2018BS EN 12977-4:2018EN 12977-1:2018购买本文件时提供的所有当前修订均包含在购买本文件中。

BS EN 12977-3:2018 specifies test methods for the performance characterization of stores which are intended for use in small custom built systems as specified in EN 12977-1:2018.Stores tested according to this document are commonly used in solar heating systems. However, the thermal performance of all other thermal stores with water as a storage medium can also be assessed according to the test methods specified in this document.The document applies to stores with a nominal volume between 50 l and 3 000 l.This document does not apply to combistores. Performance test methods for solar combistores are specified in EN 12977-4:2018.Cross References:EN 12897ISO 9459-5EN 12828EN ISO 9488 (ISO 9488:1999 Adopted)EN 12976-2EN 12897EN 15332EN 12977-2:2018EN 12977-4:2018BS EN 12977-4:2018EN 12977-1:2018All current amendments available at time of purchase are included with the purchase of this document.
