本标准规定的由“原始”制造商负责的设计验证清单，该制造商应根据第217页的表格决定如何执行这些验证，包括以下内容：与结构相关的特性验证：-材料和组件零件的强度；-组件的防护等级IP；-电气间隙和爬电距离；-防触电保护和保护电路的完整性；-开关设备和组件的合并内部电路和连接；-外部导体的端子。与性能相关的特性验证：-介电性能（50Hz下的工频耐受电压和脉冲耐受电压）；-温升限值的验证；-短路耐受强度；-电磁兼容性（EMC）；-机械操作。相反，“组装”制造商应负责：-完全按照给定说明选择和安装部件；-对每个制造组件进行常规验证的性能；-组装认证。“组件”制造商负责的标准规定的例行试验清单包括以下内容：与结构有关的特性：-外壳的防护等级IP；-电气间隙和爬电距离；-防触电保护和保护电路的完整性；-开关设备和组件的合并内部电路和连接；-外部导体的端子；-机械操作。与性能相关的特性：-介电性能（50Hz下的工频耐受电压和脉冲耐受电压）；-接线和操作。这些验证可以按任何顺序进行。常规验证由“组件”制造商进行，这一事实并不免除面板制造商在组件运输和安装后进行验证的责任。与之前的IEC 60439相比，IEC 61439引入的主要变化和新闻可以用下图所示的图表进行总结。

The list of the design verifications prescribed by the Standard under the responsibility of the “original” manufacturer who, in compliance with Table of page 217, shall decide how to perform them includes the following: Verification of the characteristics relevant to construction: - Strength of materials and parts of the assembly; - Degrees of protection IP of the assembly; - Clearances and creepage distances; - Protection against electric shock and integrity of protective circuits; - Incorporation of switching devices and of components; - Internal electrical circuits and connections; - Terminals for external conductors. Verifications of the characteristic relevant to the performance: - Dielectric properties (power-frequency withstand voltage at 50 Hz and impulse withstand voltage); - Verification of temperature-rise limits; - Short-circuit withstand strength; - Electromagnetic compatibility (EMC); - Mechanical operation. Instead, the “assembly” manufacturer shall have the responsibility of: - the choice and the fitting of the components in full compliance with the given instructions; - the performance of the routine verification on each manufactured assembly; - the assembly certification. The list of the routine tests prescribed by the Standard under the responsibility of the “assembly” manufacturer includes the following: Characteristics pertaining to construction: - Degrees of protection IP of the enclosure; - Clearances and creepage distances; - Protection against electric shock and integrity of protective circuits; - Incorporation of switching devices and of components; - Internal electrical circuits and connections; - Terminals for external conductors; - Mechanical operation. Characteristics relevant to the performance: - Dielectric properties (power-frequency withstand voltage at 50 Hz and impulse withstand voltage); - Wiring and operation. These verifications can be carried out in any sequence. The fact that the routine verifications are carried out by the “assembly” manufacturer does not exempt the panel builder from verifying them after the transport and the erection of the assembly. The main changes and news, introduced by the IEC 61439 in comparison with former IEC 60439, can be summarized with the diagrams shown in the next Figure.
