本欧洲标准涵盖了用于家庭热水或其组合的用于加热的水基储存子系统的能量性能计算。 本标准不包括这种存储系统的尺寸或检验。 表1显示了在prEN ISO 52000-1中规定的模块化结构的上下文中，该标准在EPB标准集中的相对位置。 注1:在prCEN ISO/TR 52000 2中，可以找到与每个模块相同的表格，相关EPB标准的编号和随附的技术报告已经发布或正在准备中。 注2:模块代表EPB标准，尽管一个EPB标准可以覆盖多个模块，一个模块可能被一个以上的EPB标准覆盖，例如简化和详细的方法。另见第2条和表A.1和B.1

This European Standard covers energy performance calculation of water based storage sub-systems used for heating, for domestic hot water or for combination of these. This standard does not cover sizing or inspection of such storage systems. Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1. NOTE 1 In CEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation. NOTE 2 The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1.
